Abstract
Large airway disorders encompass a large variety of diseases and pathology, with broad categories including anatomic variants, congenital abnormalities, acquired abnormalities, inflammatory/infiltrative causes, infection, and tumors. The most common diseases in each category are discussed with a focus on the salient imaging findings. Pitfalls to beware of are discussed through the article, and concludes with a general method to approaching large airways pathology that should provide the reader with a basic framework and understanding of this complex topic.

Abstract
Endobronchial tuberculosis (EBTB) is characterized by tuberculosis infection of the tracheobronchial tree. It has variable presentation but tumorous growth-like presentation in bronchus is very rare. The clinical and radiological features are non-specific, which creates a diagnostic dilemma. Bronchoscopy and biopsy of the lesion are mandatory to confirm the diagnosis. In this case series, we are presenting three unique cases of endobronchial growth diagnosed as EBTB after biopsy and evaluation of bronchoalveolar lavage (BAL) with cartridge-based nucleic acid amplification test (CBNAAT) and other ancillary investigations for tuberculosis. Four patients presented to the outpatient department with non-specific symptoms of fever, cough, hoarseness of voice, and hemoptysis. They were evaluated with chest radiograph (CXR), contrast-enhanced computed tomography (CECT) thorax, and bronchoscopy. Bronchoscopy revealed growth in the bronchus in all three cases. A biopsy was taken and BAL was performed. All cases turned out to be EBTB in histopathological examination and BAL CBNAAT. They were treated with anti-tubercular drugs and all responded well to treatment. Endobronchial tuberculosis presenting as tumorous growth in the tracheobronchial tree is rare. There should be a high index of suspicion while dealing with patients with non-specific clinical and radiological features of tuberculosis. EBTB can be misdiagnosed as malignancy in most cases. Therefore, it should be kept as a differential diagnosis while encountering a mass lesion in the trachea or bronchus during bronchoscopy.

Abstract
Post-tuberculosis lung disease (PTLD) is emerging as a significant area of global interest. As the number of patients surviving tuberculosis (TB) increases, the subsequent long-term repercussions have drawn increased attention due to their profound clinical and socioeconomic impacts. A primary obstacle to its comprehensive study has been its marked heterogeneity. The disease presents a spectrum of clinical manifestations which encompass tracheobronchial stenosis, bronchiectasis, granulomas with fibrosis, cavitation with associated aspergillosis, chronic pleural diseases, and small airway diseases-all persistent consequences of PTLD. The spectrum of symptoms a patient may experience varies based on the severity of the initial infection and the efficacy of the treatment received. As a result, the long-term management of PTLD necessitates a detailed and specific approach, addressing each manifestation individually-a tailored strategy. In the immediate aftermath (0-12 months after anti-TB chemotherapy), there should be an emphasis on monitoring for relapse, tracheobronchial stenosis, and smoking cessation. Subsequent management should focus on addressing hemoptysis, managing infection including aspergillosis, and TB-associated chronic obstructive pulmonary disease or restrictive lung function. There remains a vast expanse of knowledge to be discovered in PTLD. This review emphasizes the pressing need for comprehensive, consolidated guidelines for management of patients with PTLD.

Abstract
INTRODUCTION Lymphobronchial tuberculosis (TB) is common in children with primary TB and enlarged lymph nodes can cause airway compression of the large airways. If not treated correctly, airway compression can result in persistent and permanent parenchymal pathology, as well as irreversible lung destruction. Bronchoscopy was originally used to collect diagnostic samples; however, its role has evolved, and it is now used as an interventional tool in the diagnosis and management of complicated airway disease. Endoscopic treatment guidelines for children with TB are scarce. AREAS COVERED The role of interventional bronchoscopy in the diagnosis and management of complicated pulmonary TB will be discussed. This review will provide practical insights into how and when to perform interventional procedures in children with complicated TB for both diagnostic and therapeutic purposes. This discussion incorporates current scientific evidence and refers to adult literature, as some of the interventions have only been done in adults but may have a role in children. Limitations and future perspectives will be examined. EXPERT OPINION Pediatric pulmonary TB lends itself to endoscopic interventions as it is a disease with a good outcome if treated correctly. However, interventions must be limited to safeguard the parenchyma and prevent permanent damage.

Development, assessment and validation of a novel prediction nomogram model for risk identification of tracheobronchial tuberculosis in patients with pulmonary tuberculosis. BMJ Open Respir Res 2023; 10:e001781. [PMID: 37931979 PMCID: PMC10632898 DOI: 10.1136/bmjresp-2023-001781] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Accepted: 10/20/2023] [Indexed: 11/08/2023] Open
Abstract
OBJECTIVE Tracheobronchial tuberculosis (TBTB), a specific subtype of pulmonary tuberculosis (PTB), can lead to bronchial stenosis or bronchial occlusion if not identified early. However, there is currently no available means for predicting the risk of associated TBTB in PTB patients. The objective of this study was to establish a risk prediction nomogram model for estimating the associated TBTB risk in every PTB patient. METHODS A retrospective cohort study was conducted with 2153 PTB patients. Optimised characteristics were selected using least absolute shrinkage and selection operator regression. Multivariate logistic regression was applied to build a predictive nomogram model. Discrimination, calibration and clinical usefulness of the prediction model were assessed using C-statistics, receiver operator characteristic curves, calibration plots and decision analysis. The developed model was validated both internally and externally. RESULTS Among all PTB patients who underwent bronchoscopies (n=2153), 40.36% (n=869) were diagnosed with TBTB. A nomogram model incorporating 11 predictors was developed and displayed good discrimination with a C-statistics of 0.782, a sensitivity of 0.661 and a specificity of 0.762 and good calibration with a calibration-in-the-large of 0.052 and a calibration slope of 0.957. Model's discrimination was favourable in both internal (C-statistics, 0.782) and external (C-statistics, 0.806) validation. External validation showed satisfactory accuracy (sensitivity, 0.690; specificity, 0.804) in independent cohort. Decision curve analysis showed that the model was clinically useful when intervention was decided on at the exacerbation possibility threshold of 2.3%-99.2%. A clinical impact curve demonstrated that our model predicted high-risk estimates and true positives. CONCLUSION We developed a novel and convenient risk prediction nomogram model that enhances the risk assessment of associated TBTB in PTB patients. This nomogram can help identify high-risk PTB patients who may benefit from early bronchoscopy and aggressive treatment to prevent disease progression.

Abstract
BACKGROUND After relieving stenosis with an airway silicone stent in post-tuberculosis bronchial stenosis (PTTS), stent removal is attempted if it is determined that airway patency can be maintained even after stent removal. However, the factors affecting airway stent removal are not well known. We investigate the factors that enable the successful removal of airway silicone stents in patients with PTTS. METHODS We retrospectively analyzed PTTS patients who underwent bronchoscopic intervention from January 2004 to December 2019. Successful stent removal is defined as airway patency maintained when the stent is removed, so that reinsertion of the stent is not required. A multivariate logistic regression analysis was used to identify independent factors associated with successful stent removal at the first attempt. RESULTS Total 344 patients were analyzed. Patients were followed up for a median of 47.9 (26.9-85.2) months after airway stent insertion. Approximately 69% of PTTS patients finally maintained airway patency after the stent was removed. Factors related to successful stent removal at the first attempt were older age and male sex. Absence of parenchymal calcification, segmental consolidation & bronchiolitis, and no trachea involved lesion were relevant to the successful stent removal. Stent dwelling for 12-24 months was associated with successful stent removal compared to a duration of less than 12 months. CONCLUSION For patients whose airway patency is determined to be maintained even without a stent, it is necessary to attempt stent removal in consideration of factors related to successful stent removal.

Abstract
The healing process of tracheobronchial tuberculosis (TB) results in tracheobronchial fibrosis causing airway stenosis in 11% to 42% of patients. In Korea, where pulmonary TB is still prevalent, post-TB tracheobronchial stenosis (PTTS) is one of the main causes of benign airway stenosis causing progressive dyspnea, hypoxemia, and often life-threatening respiratory insufficiency. The development of rigid bronchoscopy replaced surgical management 30 years ago, and nowadays PTTS is mainly managed by bronchoscopic intervention in Korea. Similar to pulmonary TB, tracheobronchial TB is treated with combination of anti-TB medications. The indication of rigid bronchoscopy is more than American Thoracic Society (ATS) grade 3 dyspnea in PTTS patients. First, the narrowed airway is dilated by multiple techniques including ballooning, laser resection, and bougienation under general anesthesia. Then, most of the patients need silicone stenting to maintain the patency of dilated airway; 1.5 to 2 years after indwelling, the stent could be removed, this has shown a 70% success rate. Acute complications without mortality develop in less than 10% of patients. Subgroup analysis showed successful removal of the stent was significantly associated with male sex, young age, good baseline lung function and absence of complete one lobe collapse. In conclusion, rigid bronchoscopy could be applied to PTTS patients with acceptable efficacy and tolerable safety.

Abstract
The reported prevalence of tuberculous bronchial stenosis in children is unknown and rarely reported in English-speaking literature. In adult patients with pulmonary tuberculosis, it varies from 40% in an autopsied series in the preantibiotic era to 10% in patients who have undergone routine bronchofibroscopy in modern times. We describe our experience of four cases of confirmed bronchial stenosis due to MTB collected between January 2000 and June 2021 in this case series descriptive study. The diagnosis of bronchial stenosis due to TB was made on flexible bronchoscopy. A TB diagnosis was made if MTB was cultured from respiratory secretions, when Ziehl-Neelsen smear or GeneXpert MTB/RIF test was positive, or if a chest radiograph revealed radiographic features typical of MTB. Bronchial stenosis due to TB is rare even if airway compression is frequently seen. Although an early diagnosis of bronchial stenosis due to TB is difficult on chest X-rays, all children in this series demonstrated parenchymal changes distal to the stenosis ranging from hyperinflation and lobar collaps to bronchiectasis. If bronchial stenosis resulting from TB disease is diagnosed early, balloon dilatation as described in this report, may be an effective and safe intervention, preventing long-term complications such as irreversible lung destruction, that may require pneumonectomy.

Abstract
Purpose Tracheobronchial tuberculosis (TBTB) has been proposed to occur more commonly in female patients. However, to date, studies that systematically delineate differences between female and male patients with TB infection are lacking. We aimed to comprehensively assess the sex-specific differences in clinical manifestation, bronchoscopy performance, bacteriological examination, and imaging of TBTB in Shenzhen, China. Methods All patients with diagnosed TBTB from August 1, 2018 to July 31, 2021 at The Third People’s Hospital of Shenzhen were enrolled in the present study. Demographic information, clinical manifestations, blood tests, chest computed tomography, and bronchoscopic findings were collected, and assessed their sex-specific differences. Results Of these 331 patients, 238 patients (71.9%) were female, and 93 patients (28.1%) were male, with an overall average age of 37.3 years. The average age of male patients with TBTB was more than 5 years older than that of female patients. The prevalence of lymph fistula and diabetes mellitus was significantly higher in male patients than female patients (8.6% vs 1.7%, P = 0.005; 17.2% vs 2.1%, P < 0.001). The positive proportion of sputum smear was higher in male patients (27.9%) than in female patients (16.7%, P = 0.026). Moreover, the mean monocyte-to-lymphocyte ratio, serum CRP, and IL-6 levels were significantly higher in male patients than in female patients (P < 0.05). Conclusion In summary, in patients with TBTB diagnosis, male sex was associated with a high prevalence of diabetes mellitus, lymph fistula, and smear-positive ratio, as well as high inflammation levels. The management of young female and male patients with diabetes mellitus and high inflammation levels should be strengthened. Furthermore, to reduce the burden of TBTB, we must pay attention to the risk of TBTB in past tuberculosis patients, especially male patients under 45 years old and female patients over 45 years old.

Abstract
Tracheobronchial tuberculosis (TBTB) is most common in young, middle-aged females. Despite adequate anti-tuberculosis therapy, >90% of patients develop tracheobronchial stenosis, which has a high rate of resulting in disability. The present study aimed to explore the effect of estradiol on the development of TBTB. Estrogen receptor (ER) expression in granulomatous tissue was assessed via immunofluorescence. In order to determine whether estrogen affected the proliferation of intracellular Mycobacterium tuberculosis (Mtb), 16HBE cells were infected with Mtb in vitro, followed by estradiol treatment. Intracellular Mtb was quantified via colony counting. The effect of estradiol on autophagy of infected 16HBE cells was determined via western blotting and transmission electron microscopy. Necrosis assays of infected 16HBE cells were analyzed using propidium iodide staining and assessing lactate dehydrogenase (LDH) release. To determine how estradiol affects autophagy, infected 16HBE cells were treated with ER-specific and non-specific modulators. Reactive oxygen species (ROS) levels were analyzed via flow cytometry. Additionally, the protein expression levels of autophagy-associated proteins were determined via western blotting. Mtb could enter human lobar bronchial goblet cells and ciliated cells in patients with TBTB. The results also demonstrated that ERα was expressed in granulomatous tissue from patients with TBTB. Administration of 10−6 M estradiol reduced the number of intracellular Mtb colony-forming units in vitro in the 16HBE human bronchial epithelial cell line at day 3 after infection. Furthermore, cells treated with estradiol and infected with Mtb released less LDH at 72 h and exhibited reduced necrosis levels at 24 h compared with the untreated cells. In addition, autophagy of infected 16HBE cells was inhibited by estradiol. Estradiol and the specific ERα agonist had similar effects on autophagy in infected 16HBE cells. Additionally, treatment with the ERα antagonist abolished the inhibition of autophagy by estradiol in infected 16BHE cells. Compared with the untreated infected 16HBE cells, the ROS levels in the infected 16HBE cells treated with estradiol and the ERα agonist significantly decreased. The levels of phosphorylated (p)-mTOR and p-AKT notably increased in estradiol- and ERα agonist-treated infected 16HBE cells. In summary, estradiol may serve a key role in the development of TBTB through binding to ERα.

[PMID: 35160141 PMCID: PMC8836898 DOI: 10.3390/jcm11030676] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Revised: 01/21/2022] [Accepted: 01/26/2022] [Indexed: 12/10/2022] Open
Abstract
The diagnosis of endobronchial tuberculosis (EBTB) is difficult as it is not well visualized radiologically, and bronchoscopy is not routinely performed for tuberculosis (TB) patients. Bronchoscopic characterization via endoscopic macroscopic features can speed up the diagnosis of EBTB and prompt immediate treatment. In this study, we identified the clinical and bronchoscopic morphology of 17 patients who were diagnosed with EBTB from 2018 to 2020. Demographics, radiological, microbiological and histopathological data were recorded. Endobronchial lesions were classified according to Chung classification. The diagnosis was made based on a histopathological examination (HPE) of endobronchial biopsy, and/or positive ‘Acid-fast bacilli’ (AFB) microscopy/Mycobacterium tuberculosis (MTB) culture on microbiological examination of bronchial alveolar lavage (BAL) and/or positive MTB culture on endobronchial biopsy specimens. Furthermore, EBTB was predominant in young women, age 20 to 49 years old, with a male to female ratio of 1 to 2. Underlying comorbidities were found in 53% of the patients. Cough, fever and weight loss were the main symptoms (23.5%). The indications for bronchoscopy are smear-negative TB and persistent consolidation on chest radiographs. Consolidation was the main radiological finding (53%). An active caseating lesion was the main EBTB endobronchial subtype (53%). The leading HPE finding was caseating granulomatous inflammation (47%). All patients showed good clinical response to TB treatment. Repeated bronchoscopy in six patients post TB treatment showed a complete resolution of the endobronchial lesion. EBTB bronchoscopic characterization is paramount to ensure correct diagnosis, immediate treatment and to prevent complication.

Sun Y, Zhang Q, Zhang Q, Liu C, Zhang H, Fu Y, Liu Y, Hou G. Diagnostic Efficacy of Xpert MTB/RIF Assay in Bronchoalveolar Lavage Fluid for Tracheobronchial Tuberculosis: A Retrospective Analysis. Front Med (Lausanne) 2021; 8:682107. [PMID: 34485328 PMCID: PMC8416264 DOI: 10.3389/fmed.2021.682107] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Accepted: 07/12/2021] [Indexed: 01/04/2023] Open
Abstract
Background: The Xpert Mycobacterium tuberculosis/rifampin (MTB/RIF) assay has shown good diagnostic efficacy in brushing and biopsy tissue samples from patients with tracheobronchial tuberculosis (TBTB). However, its diagnostic value in bronchoalveolar lavage fluid (BALF) is still unclear. Therefore, the present retrospective study aimed to evaluate the diagnostic value of the Xpert MTB/RIF assay in BALF. Methods: The clinical data of 266 patients with suspected TBTB from January 2018 to October 2020 were pooled with complete details of bronchial brush and bronchoalveolar lavage samples. Smears of the bronchial brushings were stained with Auramine O stain to detect acid-fast bacilli (AFB), and BALF samples were used for culturing MTB with the BACTEC MGIT 960 system and the Xpert MTB/RIF assay. The diagnostic performance of these methods was assessed and compared. Results: A total of 266 patients suspected to have TBTB were enrolled in the final analysis. Of these patients, 179 patients were confirmed to have TBTB and 87 patients were non-TBTB. The sensitivity of the Xpert MTB/RIF assay in BALF (87.2%) was significantly higher than that of the brush smear for AFB (35.2%, p < 0.001). No significant difference was observed between the sensitivities of the Xpert MTB/RIF assay in BALF and MTB culture in BALF (87.2 vs. 84.9%, p = 0.542). The specificities of the Xpert MTB/RIF assay in BALF, MTB culture in BALF, and the bronchial brush smear were 97.7, 97.7, and 98.9%, respectively. The positive predictive value (PPV) and negative predictive value (NPV) of the Xpert MTB/RIF assay in BALF, MTB culture in BALF, and the bronchial brush smear were 98.7 and 78.7%, 98.7 and 75.9%, and 98.4 and 42.6%, respectively. Among the MTB culture-positive patients with TBTB detected by the Xpert assay, 27.0% (20/74) were identified to be resistant to RIF. Conclusions: The Xpert MTB/RIF assay in BALF enables a rapid and accurate diagnosis of TBTB and identification of RIF resistance, which is crucial for timely and proper treatment. Moreover, in patients with TBTB, BALF could be used as an alternative to bronchial brushing and biopsy tissues for the Xpert MTB/RIF assay.

Abstract
BACKGROUND AND AIMS Post-tuberculosis bronchial stenosis (PTBS) is one of the most common complications of tracheobronchial tuberculosis. Silicone stent serves as a major treatment for maintaining airway patency. However, silicone stent placement remains a large challenge in patients with severe cicatricial PTBS. Our objective was to evaluate the efficacy and safety of covered, self-expanding, metallic stents (SEMSs) as a transition to silicone stent implantation for treating severe PTBS. METHODS We retrospectively reviewed the data of patients with severe PTBS who received airway stenting in the First Affiliated Hospital of Guangdong Medical University between September 2015 and May 2019. The types of the stent, intervention procedures, bronchoscopic findings, clinical outcomes and related complications were collected and analyzed. RESULTS Fifty-eight cases with severe PTBS were included in this study. Thirteen (22.4%) of the patients received bronchial silicone stent implantation immediately after dilations. For the remaining 45 (77.6%) patients, silicone stents could not be deployed after dilations and SEMSs implantation was implemented as a bridge to silicone stenting. The SEMSs were placed for an interval of 28.4 ± 11.1 days. All of the silicone stents were inserted successfully following the removal of SEMSs. No SEMS-related complication occurred. The subgroup analysis showed that patients who received transitional SEMSs had less luminal caliber but fewer transbronchial dilations before silicone stent implantation (p < 0.05). CONCLUSION Covered SEMS placement as a transition to silicone stenting could serve as a feasible procedure to reduce complications and improve the success rate of silicone stent implantation in patients with severe PTBS.The reviews of this paper are available via the supplemental material section.

Clinical significance of serum transforming growth factor-β1 and procollagen type I N-propeptide in post-tuberculosis tracheobronchial stenosis. Exp Ther Med 2021; 21:570. [PMID: 33850542 PMCID: PMC8027726 DOI: 10.3892/etm.2021.10002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Accepted: 02/25/2021] [Indexed: 11/05/2022] Open
Abstract
Non-invasive strategies for monitoring post-tuberculosis (TB) tracheobronchial stenosis (PTTS) are clinically important but currently lacking. Transforming growth factor-β1 (TGF-β1) and procollagen type I N-propeptide (PINP) have been identified as markers of fibrosis. The present study aimed to investigate the clinical significance of serum TGF-β1 and PINP in PTTS. Serum samples were collected from 119 patients with tracheobronchial TB after the condition was treated for at least 6 months (59 patients with airway stenosis and 60 patients with no stenosis). Serum TGF-β1 and PINP levels were measured using ELISA and compared between the groups. Relationships between serum TGF-β1 and PINP levels and clinical characteristics, interventional bronchoscopy and outcomes of airway stenosis were analysed. The correlation between TGF-β1 and PINP, and their diagnostic efficacy for airway stenosis were also analysed. The TGF-β1 and PINP levels in the airway stenosis group were higher than those in the non-stenosis group. Furthermore, airway stenosis with atelectasis or mucus plugging was associated with higher TGF-β1 levels, and airway stenosis with atelectasis, mucus plugging, right main bronchus stenosis or severe airway tracheal stenosis was associated with higher PINP levels. In addition, TGF-β1 and PINP levels increased after interventional bronchoscopy therapy and airway stenosis with recurrent stenosis was associated with higher baseline levels of both markers. Finally, TGF-β1 levels were positively correlated with PINP levels in patients with airway stenosis. The area under the receiver operating characteristic curve of TGF-β1 and PINP for distinguishing airway stenosis from non-stenosis cases was 0.824 (95% CI: 0.748-0.900) and 0.863 (95% CI: 0.796-0.930), respectively. Therefore, TGF-β1 and PINP are potential biomarkers that may be useful for diagnosing and monitoring PTTS.

Abstract
Tracheobronchial stenosis secondary to endobronchial tuberculosis (TSTB) is a rare but debilitating complication of endobronchial tuberculosis (EBTB). Topical mitomycin-C (TMC) has been successfully utilized to restore airway patency and to prevent recurrence of TSTB, although little is known about its exact efficacy. Here, we report the biggest case series to date involving seven patients who received TMC as part of multimodality endoscopic treatment for TSTB with varying levels of success. All patients presented with dyspnoea during or after treatment completion for pulmonary tuberculosis (PTB). Four patients had short-segment concentric membranous TSTB while two patients had concurrent bronchomalacia. Another one patient had a thick fibrotic band adjacent to luminal opening. We hypothesize that TMC is more efficacious in short membranous stenosis without concurrent bronchomalacia and/or thick fibrotic bands. More studies are needed to bridge the current gaps in knowledge regarding the optimal role and benefits of TMC for TSTB patients.

Abstract
Objectives: Posttubercular tracheobronchial stenosis is a troublesome sequela of tracheobronchial tuberculosis. Surgical resection is the treatment of choice when repeated bronchoscopic dilatations fail. Herein, we aim to present our surgical experience in the management of this problem and also to evaluate factors affecting the surgical outcomes. Materials and Methods: This is a retrospective analysis of a prospectively maintained database at a dedicated thoracic surgical unit in New Delhi, India, over 8 years. An analysis of demographic characteristics, perioperative variables including complications were carried out. The occurrence of postoperative complications, and/or hospital stay of >7 days was considered as “poor” surgical outcomes. Various parameters were analyzed to assess the factors predicting surgical outcomes. Results: A total of 20 patients were surgically managed in the study period. Two patients had tracheal stenosis. The left main bronchus was involved in 16 patients. In these 16 cases, 12 cases underwent lung preserving surgery (bronchial sleeve resection and sleeve lobectomy) and rest of 4 cases required pneumonectomy. All postoperative complications occurred in 5 (25%) patients. Prolonged air leak was the most common postoperative complication. On univariate analysis, surgical outcomes were poor in patients who had longer duration of symptoms (P = 0.03) and with >2 episodes of preoperative balloon dilatations (<0.001). On multivariate analysis, “total number of dilatations <4 times,” emerged as a significant predictive factor for lung preservation surgery. Conclusions: Surgical intervention is safe, feasible, and effective in tubercular tracheobronchial stenoses which fail to respond to bronchoscopic interventions. Early referral for surgery favors lung preservation.

Abstract
Historically associated with poor prognosis seen in advanced disease, laryngeal tuberculosis (LTB) now represents only 1% of all cases of tuberculosis (TB). The incidence of LTB has decreased drastically with the introduction of anti-tubercular drugs. LTB can be primary or secondary to pulmonary tuberculosis. LTB can mimic laryngeal cancer. We present a case of primary laryngeal TB with descending tracheobronchial spread in an immunocompetent 71-year-old female who developed progressive dysphonia over several months with unintentional weight loss and non-productive cough. Non-contrast enhanced computed tomography (CT) revealed clustering of subcentimeter stellate nodules in the right upper lung field with an enlarging ground-glass opacity in the right lower lung but did not show structural abnormalities within the neck. Positron emission tomography (PET) showed pathologic fluorodeoxyglucose (FDG) uptake within the larynx and trachea with extension into the left mainstream bronchus as well as the proximal left upper and lower lobe bronchi. Diffuse standardized uptake value (SUV) was greatest in the larynx (20.5). Polymerase chain reaction (PCR) on bronchoscope sputum specimen confirmed Mycobacterium tuberculosis. Findings were consistent with primary laryngeal TB with endobronchial extension. She was started on a four-drug regimen comprising of isoniazid, rifampin, ethambutol, and pyrazinamide with a good response. Her close contacts were treated as well. This case highlights the unusual spread of primary laryngeal TB in an immunocompetent host. Early diagnosis can limit adverse complications and unnecessary exposure to healthcare workers. To our knowledge, this is the first case of primary LTB with proximal spread to the tracheobronchial and pulmonary tuberculosis.

Abstract
Tuberculosis (TB) remains a serious global public health problem in the present. TB also affects other sites (extrapulmonary tuberculosis, EPTB), and accounts for a significant proportion of tuberculosis cases worldwide. In order to comprehensively understand epidemiology of EBTB in China, and improve early diagnosis and treatment, we conducted a large-scale multi-center observational study to assess the demographic data and the prevalence of common EPTB inpatients, and further evaluate the prevalence of EPTB concurrent with Pulmonary tuberculosis (PTB) and the associations between multiple EPTB types and gender-age group in China. All consecutive age≥15yr inpatients with a confirmed diagnosis of EPTB during the period from January 2011 to December 2017 were included in the study. The descriptive statistical analysis included median and quartile measurements for continuous variables, and frequencies and proportions with 95% confidence intervals (CIs) for categorical variables. Multinomial logistic regression analysis was used to compare the association of multiple EPTB types between age group and gender. The results showed that the proportion of 15–24 years and 25–34 years in EPTB inpatients were the most and the ratio of male: female was 1.51. Approximately 70% of EPTB inpatients were concurrent with PTB or other types of EPTB. The most common of EPTB was tuberculous pleurisy (50.15%), followed by bronchial tuberculosis (14.96%), tuberculous lymphadenitis of the neck (7.24%), tuberculous meningitis (7.23%), etc. It was found that many EPTB inpatients concurrent with PTB. The highest prevalence of EPTB concurrent with PTB was pharyngeal/laryngeal tuberculosis (91.31%), followed by bronchial tuberculosis (89.52%), tuberculosis of hilar lymph nodes (79.52%), tuberculosis of mediastinal lymph nodes (79.13%), intestinal tuberculosis (72.04%), tuberculous pleurisy (65.31%) and tuberculous meningitis (62.64%), etc. The results from EPTB concurrent with PTB suggested that females EPTB inpatients were less likely to be at higher risk of concurrent PTB (aOR = 0.819, 95%CI:0.803–0.835) after adjusted by age. As age increasing, the trend risk of concurrent PTB decreased (aOR = 0.994, 95%CI: 0.989–0.999) after adjusted by gender. Our study demonstrated that the common EPTB were tuberculous pleurisy, bronchial tuberculosis, tuberculous lymphadenitis of the neck, tuberculous meningitis, etc. A majority of patients with pharyngeal/laryngeal tuberculosis, bronchial tuberculosis, tuberculosis of hilar/mediastinal lymph nodes, intestinal tuberculosis, tuberculous pleurisy, tuberculous meningitis, etc. were concurrent with PTB. Female EPTB inpatients were less likely to be at higher risk of concurrent PTB, and as age increasing, the trend risk of concurrent PTB decreased. The clinicians should be alert to the presence of concurrent tuberculosis in EPTB, and all suspected cases of EPTB should be assessed for concomitant PTB to determine whether the case is infectious and to help for early diagnosis and treatment.

Abstract
Background Patients with tracheobronchial stenosis due to tuberculosis (TSTB) have a variable clinical course and response to treatment including airway intervention. There are no clear guidelines on the best approach to manage such patients. This study examines long-term outcomes of patients with TSTB and factors associated with recurrent symptoms or need for repeat airway intervention following initial bronchoscopic intervention. Methods This is a retrospective analysis of patients with TSTB over an 18-year period. Symptoms, radiological, bronchoscopic findings, airway interventions and complications were obtained. Multivariate logistic regression analysis was performed to identify factors predictive of recurrence of symptoms or need for repeat airway intervention. Results A total of 131 patients with mean age 50±18 years and median follow-up 5 (interquartile range, 2–10) years were included. Nineteen (29.7%) patients underwent balloon dilatation alone, 22 (34.4%) had additional resection or stenting, and 19 (29.7%) underwent all 3 procedures. Among patients conservatively managed, a larger proportion (55.6%) of patients with no recurrence of symptoms had active TB. Patients who developed recurrent symptoms had longer symptom duration (12 vs. 3 months, P=0.025), and more had recurrent lower respiratory tract infections (50% vs. 5.6%, P=0.003), lung collapse (90.0% vs. 41.7%, P=0.011) or linear fibrosis (70.0% vs. 30.6%, P=0.033) compared to those without recurrent symptoms. Bronchomalacia (OR =17.18; 95% CI, 3.43–86.18) and prior bronchoscopic airway resection (OR =4.97; 95% CI, 1.20–20.60) were strongly associated with the recurrence of symptoms or need for repeat airway intervention on multivariate logistic regression analysis. Conclusions Bronchomalacia and prior bronchoscopic airway resection are associated with the recurrence of symptoms despite airway intervention. Patients who are diagnosed with TSTB early in the course of active TB may be conservatively managed.

Abstract
Recently, our understanding of the elusive bacterial communities in the lower respiratory tract and their role in chronic lung disease has increased significantly. However, little is known about the respiratory microorganisms in patients with endobronchial tuberculosis (EBTB), which is a chronic inflammatory disease characterized by destruction of the tracheobronchial tree due to Mycobacterium tuberculosis (MTB) infection. We retrospectively reviewed data for histopathologically and microbiologically confirmed EBTB patients diagnosed at a tertiary referral hospital in South Korea between January 2013 and January 2019. Bacterial cultures were performed on bronchial washing from these patients at the time of EBTB diagnosis. A total of 216 patients with EBTB were included in the study. The median age was 73 years and 142 (65.7%) patients were female. Bacteria were detected in 42 (19.4%) patients. Additionally, bacterial co-infection was present in 6 (2.8%) patients. Apart from MTB, the most common microorganisms identified were Staphylococcus aureus (n = 14, 33.3%) followed by Klebsiella species (n = 12, 28.6%; 10 Klebsiella pneumoniae, 2 Klebsiella oxytoca), Streptococcus species (n = 5, 11.9%), Enterobacter species (n = 4, 9.5%), and Pseudomonas aeruginosa (n = 3, 7.1%). A variety of microorganisms were isolated from the bronchial washing indicating that changes in microorganism composition occur in the airways of patients with EBTB. Further studies are needed to investigate the clinical significance of this finding.

Abstract
Tuberculosis (TB) is one of the top ten leading causes of death worldwide. The causative agent of TB is Mycobacterium tuberculosis. Acute tuberculous pneumonia (TP) is an acute form of pulmonary TB. However, acute TP and non-tuberculous community-acquired pneumonia can be easily confused, resulting in deterioration of TP due to delayed treatment. Therefore, rapid and accurate diagnosis of acute TP is crucial in order to stop the transmission of TB. Moreover, development of new diagnostic tools (technologies and approaches), and flexible application of different therapy schemes will help to reduce the incidence of TP and promote the goal of ending the TB epidemic.

Abstract
Conditions, where the patient's immune system is compromised are the main risk factor for mucormycosis. Approximately 23% of the world's population is estimated to have a latent Mycobacterium tuberculosis infection and more than 10 million new cases were estimated in 2017. Pulmonary mucormycosis and tuberculosis co-infections are very rare. We present the case of a 56-year-old insulin-dependent diabetic patient with a pulmonary mucormycosis and tuberculosis co-infection. While the patient did not suffer from ketoacidosis, she had poor glycemic control. A chest X-ray and a computed tomography showed nodular and cavitary lesions in both lungs. The patient was diagnosed through a biopsy of the bronchial mucosa and an RT-PCR for M. tuberculosis from bronchoalveolar lavage. The patient was treated with the recommended 4-drug regimen for TB (i.e. isoniazid, rifampin, pyrazinamide, and ethambutol); concurrently, amphotericin B deoxycholate was administered to treat the mucormycosis infection. Thirty days after initial hospital admission the patient underwent a lobectomy on the right lung. The case described here is only the sixth case reported in the literature of concomitant pulmonary tuberculosis and mucormycosis and the third case associated with a TB and mucormycosis co-infection involving an uncontrolled DM patient to survive.

Abstract
Background Patients with the whole lung atelectasis caused by endobronchial tuberculosis (EBTB) in main bronchus usually undergo pneumonectomy, which may result in a large number of complications and poor quality of life. In the study, we summarized our experience with bronchoplasty treatment for the whole lung atelectasis caused by EBTB in main bronchus, in which long-term medical therapy failed. Methods Eight patients with whole lung atelectasis, who suffered from EBTB in main bronchus, were treated by bronchoplasty: 3 patients were treated by bronchoplasty for the left main bronchus; 2 patients were treated by sleeve resection of right upper and middle lobes; and 3 patients were treated by sleeve resection of left upper lobe. The patients were followed up for a period of time. Results All the patients were cured by surgery, were discharged from hospital uneventfully, had anastomotic patency and good lung expansion. Neither bronchopleural fistula nor recurrence was observed. Conclusions Bronchoplasty is an effective treatment for atelectasis of the whole lung caused by EBTB in the main bronchus, in which long-term medical therapy failed. Prognosis was favorable.

Abstract
RATONALE Cicatricial bronchial stenosis or obstruction occurring in the healing process of endobronchial tuberculosis (ET) is a problematic complication of tuberculous airway lesions. Prevention by internal medical treatment is desired. PATIENT CONCERNS This case series describes four patients who diagnosed ET with Type IIIb (protruding ulcer-type) based on Arai's classification of bronchoscopic findings of bronchial tuberculosis. DIAGNOSES Endobronchial tuberculosis. INTERVENTIONS A local steroid spray was applied bronchoscopically to active protruding ulcer-type lesions (which are likely to cause cicatricial stenosis) that extended in the transverse direction and occupied one-half or more of the circumference on bronchoscopy. OUTCOMES Cicatricial stenosis was prevented in two of four patients. Treatment was discontinued in athird patient because tolerance could not be achieved, although the patient's condition had improved. In the fourth patient, treatment was switched to systemic steroid administration because of a problem with tolerance and the broad range of the lesion; however, stenosis remained. LESSONS Local steroid spray-applied bronchoscopically to bronchial tuberculosis lesions in the ulcer formation and granulation periods may help prevent stenosis.

Abstract
Tuberculosis (TB) is one of the leading causes of morbidity and mortality worldwide. Early diagnosis and treatment are key to prevent Mycobacterium tuberculosis transmission. Bronchoscopy can play a primary role in pulmonary TB diagnosis, particularly for suspected patients with scarce sputum or sputum smear negativity, and with endobronchial disease. Bronchoscopic needle aspiration techniques are accurate and safe means adopted to investigate hilar and mediastinal lymph nodes in cases of suspected TB lymphadenopathy. Tracheobronchial stenosis represents the worst complication of endobronchial tuberculosis. Bronchoscopic procedures are less invasive therapeutic strategies than conventional surgery to be adopted in the management of TB-related stenosis. We conducted a non-systematic review aimed at describing the scientific literature on the role of bronchoscopic techniques in the diagnosis and therapy of patients with TB. We focused on three main areas of interventions: bronchoscopic diagnosis of smear negative/sputum scarce TB patients, endobronchial TB diagnosis and treatment and needle aspiration techniques for intrathoracic TB lymphadenopathy. We described experiences on bronchoalveolar lavage, bronchial washing, and biopsy techniques for the diagnosis of patients with tracheobronchial and pulmonary TB; furthermore, we described the role played by conventional and ultrasound-guided transbronchial needle aspiration in the diagnosis of suspected hilar and mediastinal TB adenopathy. Finally, we assessed the role of the bronchoscopic therapy in the treatment of endobronchial TB and its complications, focusing on dilation techniques (such as balloon dilation and airway stenting) and ablative procedures (both heat and cold therapies).

Abstract
Endobronchial Tuberculosis is hazardous in causing circumferential narrowing of tracheobronchial tree despite the eradication of tubercle bacilli in the initial insult from Pulmonary Tuberculosis. They may present as treatment resistant bronchial asthma and pose challenge to airway management in the acute setting. We present a 25 year-old lady who was newly diagnosed bronchial asthma with a past history of Pulmonary Tuberculosis that had completed treatment. She presented with sudden onset of difficulty breathing associated with noisy breathing for 3 days and hoarseness of voice for 6 months. Due to resistant bronchospasm, attempts were made to secure the airway which led to unanticipated difficult intubation and ventilation. Subsequent investigations confirmed the diagnosis of Endobronchial Tuberculosis and patient was managed successfully with anti TB medication, corticosteroids and multiple sessions of tracheal dilatation for tracheal stenosis. This case highlights the unusual cause of difficulty in intubation and ventilation due to Endobronchial Tuberculosis, which required medical and surgical intervention to improve the condition.

Abstract
Central airway obstructive infections (CAOI) are challenging medical conditions that may represent an advanced and complicated process of ongoing infections. The epidemiology of CAOI is unknown as well as the pathophysiology and the mechanism of development. This is due to sparse data in the literature that consists mainly of case reports and retrospective case series. CAOI can be caused by fungal, bacterial, parasitic and viral infections. Most patients with CAOI can be diagnosed clinically and with chest imaging, which demonstrate obstruction of the central airways. However, bronchoscopy is commonly used to confirm and obtain a specific diagnosis to guide specific therapy. In recent years, interventional pulmonology (IP) is becoming widely available and offer a minimally invasive approach for the management of central airway diseases such as cancers, benign strictures, and other conditions. Various bronchoscopic modalities are used to treat central airway obstruction (CAO), such as mechanical debulking, endobronchial laser therapy, electrocautery, argon plasma coagulation, cryotherapy, and airway stenting. In patients with CAOI, the role of therapeutic bronchoscopy is not clearly defined, but many isolated reports in the literature described bronchoscopic intervention in combination with medical therapy as the initial management approach. In this paper, we present cases of CAOI that underwent bronchoscopic intervention as part of their management. We described the infectious etiology, locations, bronchoscopic findings and bronchoscopic modalities for airway management.

Abstract
Objective: To determine the proportional distribution of endobronchial tuberculosis (EBTB) subtypes and to evaluate the types of bronchoscopic diagnostic procedures that can prove granulomatous inflammation. Methods: This was a retrospective study of 18 HIV-negative patients with biopsy-proven EBTB treated between 2010 and 2014. Results: The most common EBTB subtypes, as classified by the bronchoscopic features, were tumorous and granular (in 22.2% for both). Sputum smear microscopy was performed in 11 patients and was positive for AFB in 4 (36.3%). Sputum culture was also performed in 11 patients and was positive for Mycobacterium tuberculosis in 10 (90.9%). Smear microscopy of BAL fluid (BALF) was performed in 16 patients and was positive for AFB in 10 (62.5%). Culture of BALF was also performed in 16 patients and was positive for M. tuberculosis in 15 (93.7%). Culture of BALF was positive for M. tuberculosis in 93.7% of the 16 patients tested. Among the 18 patients with EBTB, granulomatous inflammation was proven by the following bronchoscopic diagnostic procedures: bronchial mucosal biopsy, in 8 (44.4%); bronchial brushing, in 7 (38.8%); fine-needle aspiration biopsy, in 2 (11.1%); and BAL, in 2 (11.1%). Bronchial anthracofibrosis was observed in 5 (27.7%) of the 18 cases evaluated. Conclusions: In our sample of EBTB patients, the most common subtypes were the tumorous and granular subtypes. We recommend that sputum samples and BALF samples be evaluated by smear microscopy for AFB and by culture for M. tuberculosis, which could increase the rates of early diagnosis of EBTB. We also recommend that bronchial brushing be employed together with other bronchoscopic diagnostic procedures in patients suspected of having EBTB.

Abstract
BACKGROUND/AIM The endobronchial tuberculosis (EBTB) is an uncommon type of tuberculosis. The respiratory symptoms in EBTB are usually nonspecific and misleading. The aim of the study is to determine the clinical features and diagnostic aspects of EBTB. PATIENTS AND METHODS Twenty-eight cases of endobronchial tuberculosis collected from January 2009 to October 2015. RESULTS EBTB was found in 16 females and 12 males. The mean age was 48 years. The history of tuberculosis and tuberculosis contagion were not found in any case. The respiratory symptoms were dominated by cough and dyspnea. Hemoptysis was found in 7 cases. The chest X-ray showed associated pulmonary lesions in 26 cases. Bronchoscopy finded an endobronchial granular lesion in 15 cases, a tumorous pattern in 7 cases; a thickening spurs in 4 cases and ganglio-bronchial fistula in two cases. Bronchial biopsies had found a caseo-follicular tuberculosis in 27 cases. Pleural biopsy confirmed associated pleural tuberculosis in one case. The research of Koch bacillus in the sputum was positive in 13 cases and culture in 6 cases. The antituberculosis treatment was started in all patients and an oral corticosteroids treatment was associated in 5 cases. The evolution was good in 26 cases. CONCLUSION This study showed clinical, radiological and endoscopic bronchial tuberculosis polymorphism making its diagnosis difficult and the importance of a bacteriological and/or histological confirmation.

Abstract
Objectives To describe the imaging features of the central airway pathology, correlating the findings with those in pathology and virtual endoscopy. To propose a schematic and practical approach to reach diagnoses, placing strong emphasis on multidetector computed tomography (MDCT) findings. Methods We reviewed our thoracic pathology database and the central airway pathology-related literature. Best cases were selected to illustrate the main features of each disease. MDCT was performed in all cases. Multiplanar and volume-rendering reconstructions were obtained when necessary. Virtual endoscopy was obtained from the CT with dedicated software. Results Pathological conditions affecting the central airways are a heterogeneous group of diseases. Focal alterations include benign neoplasms, malignant neoplasms, and non-neoplastic conditions. Diffuse abnormalities are divided into those that produce dilation and those that produce stenosis and tracheobronchomalacia. Direct bronchoscopy (DB) visualises the mucosal layer and is an important diagnostic and therapeutic weapon. However, assessing the deep layers or the adjacent tissue is not possible. MDCT and post-processing techniques such as virtual bronchoscopy (VB) provide an excellent evaluation of the airway wall. Conclusion This review presents the complete spectrum of the central airway pathology with its clinical, pathological and radiological features. Teaching points • Dividing diseases into diffuse and focal lesions helps narrow the differential diagnosis. • Focal lesions with nodularity are more likely to correspond to tumours. • Focal lesions with stenosis are more likely to correspond to inflammatory disease. • Posterior wall involvement is the main feature in diffuse lesions with stenosis.

Abstract
Endobronchial tuberculosis (EBTB) is defined as tuberculous infection of the tracheobronchial tree. The exact pathogenesis is unclear, and it has a heterogenous clinical course. Its diagnosis requires the clinician to have a high index of suspicion based on clinical symptoms and radiological features. Computed tomography and bronchoscopy are useful tools in its evaluation. The goal of treatment is in the eradication of tuberculous bacilli with appropriate anti-tuberculous therapy. Use of corticosteroids is controversial for the prevention of tracheobronchial stenosis. Interventional bronchoscopy or surgical intervention is employed to restore airway patency once significant stenosis occurs.

Abstract
Endobronchial tuberculosis (EBTB) is a tuberculous infection of the tracheobronchial tree with microbial and histopathological evidence. Patients may present with symptoms secondary to disease itself or from the complication of disease like endobronchial obstruction. Diagnosis requires a high index of suspicion. Computed tomography (CT) and bronchoscopy along with microbiological investigations are the most useful diagnostic tools for the confirmation as well as for the evaluation of the tracheobronchial stenosis. The goals of treatment are eradication of tubercle bacilli with anti-tubercular medications and the prevention of airway stenosis. Interventional Bronchoscopic techniques and surgery is required for those patients who develop severe tracheobronchial stenosis that causing significant symptoms including dyspnea, repeated post obstructive pneumonia or bronchiectasis.

Abstract
Tracheobronchial tuberculosis (TBTB) is reported in approximately 10% to 39% of the patients with pulmonary tuberculosis. It is defined as the tubercle infection of the trachea and or bronchi. Due to its non-specific presentation, insidious onset and normal chest radiography in about 10-20% of the patients, the diagnosis is delayed. Bronchoscopy is the most definite method of diagnosis which provides adequate specimens for microbiological and histopathological diagnosis. Tracheobronchial stenosis is one of the most common long term complications of TBTB resulting in significant morbidity. It is estimated that 90% of patients with TBTB have some degree of tracheal and or bronchial stenosis. In this review article, we will discuss the pathogenesis, symptoms, imaging, bronchoscopic findings, and treatment of TBTB and management of tracheobronchial stenosis.

Abstract
Mucoepidermoid carcinoma (MEC) is an uncommon primary lung tumor. It usually involves large airways and presents clinically and radiologically with nonspecific features. Because of nonspecific presentation diagnosis is frequently delayed. We report the case of a 29-year-old male patient wherein a clinico-radiological consideration of tuberculosis (TB) led to a prolonged treatment with anti-TB medications without response. Flexible bronchoscopic biopsy confirmed the diagnosis of MEC following that the patient underwent curative surgical resection.

Tracheobronchopathia Osteochondroplastica: a rare case report of a non-smoker and non-atopic patient, with a long history of wheezing since childhood. Multidiscip Respir Med 2016; 11:16.

Abstract
Background Tracheobronchopathia Osteochondroplastica (TBPO) is an uncommon and benign condition characterized by osseous or metaplastic cartilaginous 1–3 mm nodules in the submucosa of the tracheo-bronchial tree. Posterior membranous wall of trachea is typically spared. Ecchondrosis and exostosis nodules can cause chronic inflammation and mucosal metaplasia, stiffness and airway obstruction. The prevalence of this disease, often asymptomatic or associated with nonspecific symptoms, is underestimated, and the mean age at diagnosis is 50 years. Case presentation We report a case of a 49 year old male, non-smoker. He was a smith, homeless, born in Romania and reported a diagnosis of asthma since childhood. He was admitted to our Respiratory Unit presenting low-grade fever with profuse sweating, cough, purulent sputum, and ground-glass opacity with irregularity in main bronchi detected by High-Resolution Computed Tomography (HRCT) scan. Fibrobronchoscopy revealed the presence of mucosal irregularities up to the segmental bronchi entrance. Histological examination showed nodules of osseouscartilaginous nature, consistent with TBPO. Microbiological tests of Bronchoalveolar Lavage fluid also revealed an infection by Pseudomonas Aeruginosa. Conclusion TBPO is a rare disease characterized by wheezing, cough, hemoptysis, and recurrent pulmonary infections, with typical onset during adulthood. In the case reported, the symptoms began in childhood, although they had been misinterpreted as asthma. Even if childhood-onset is not reported in literature, it is likely that small changes occur in the first few years of life and become more evident in adulthood. The involvement of segmental and sub-segmental bronchi, usually spared in TBPO, could explain the presence of wheezing and non-productive cough reported by our patient since childhood.

Abstract
BACKGROUND Tracheobronchial stenosis is a known complication of endobronchial tuberculosis. Despite antituberculous and steroid therapy, the development of bronchial stenosis is usually irreversible and requires airway patency to be restored by either bronchoscopic or surgical interventions. We report the use of balloon dilatation and topical mitomycin-C to successful restore airway patency. CASE PRESENTATION We present a 24-year old lady with previous pulmonary tuberculosis and laryngeal tuberculosis in 2007 and 2013 respectively who presented with worsening dyspnoea and stridor. She had total left lung collapse with stenosis of both the upper trachea and left main bronchus. She underwent successful bronchoscopic balloon and manual rigid tube dilatation with topical mitomycin-C application over the stenotic tracheal segment. A second bronchoscopic intervention was performed after 20 weeks for the left main bronchus stenosis with serial balloon dilatation and topical mitomycin-C application. These interventions led to significant clinical and radiographic improvements. CONCLUSION This case highlights that balloon dilatation and topical mitomycin-C application should be considered in selected patients with tracheobronchial stenosis following endobronchial tuberculosis, avoiding airway stenting and invasive surgical intervention.

Abstract
A 19-year-old Vietnamese lady was diagnosed with culture positive, left upper lobe pulmonary tuberculosis for which medical treatment was initiated. Four months into treatment, she developed a 'rubber-band-like' stretching sensation in her left chest with wheezing and shortness of breath. Decreased respiratory excursion over the left lung was present on physical-examination. Chest-Xray revealed left-upper-lobe collapse with leftward deviation of the trachea and mediastinum. CT thorax revealed a long segment of stenosis in the left mainstem bronchus. FEV1 was 1.26 L (45% predicted), FVC 1.53 L (49% predicted), FEV1/FVC 82% (95% predicted) indicating airway limitation. Ventilation-perfusion scan noted 9.8% ventilation to the left lung and 92.8% to the right lung and 7.6% perfusion to the left lung and 92.4% to the right lung. Bronchoscopy was notable for pin point stenosis of the left mainstem bronchus beyond which was inflamed mucosa and abnormal cartilage rings in the left upper and middle lobe bronchi. Nine months of medical therapy for tuberculosis along with oral steroid taper was completed successfully; however the patient has required six serial bronchscopies with dilatations without stent placement at four to six week intervals due to partial restenosis, with the last bronchoscopy at four months after completion of tuberculosis therapy.

Abstract
Endobronchial tuberculosis (EBTB) is a sequelae of pulmonary tuberculosis (TB) that extends to the endobronchial or endotracheal wall causing inflammation, edema, ulceration, granulation or fibrosis of mucosa and submucosa. This case depicts a 20 year old foreign-born woman with a history of active pulmonary TB on anti-TB chemotherapy, who presented with worsening stridor, dyspnea, cough and weight loss. The disease state was diagnosed with multiple modalities including, spirometry, CT scan of the neck, and bronchoscopy. The biopsies of the tracheal web revealed fibrotic tissue without any granulomas or malignancy establishing the diagnosis of EBTB. Serial balloon dilations and anti-neoplastic therapy with Mitomycin C was used to accomplish sufficient airway patency to relieve her symptoms. ETBT is a rare consequence of TB, which although has a low incidence in the United States, so physicians should have a high clinical suspicion based on the need for prompt intervention.

Abstract
BACKGROUND AND AIMS Bronchoscopy is an important method for diagnosing respiratory disease. Multiple tracheobronchial nodules are rarely reported and their causes remain unclear. OBJECTIVES The aim of this study was to describe the clinical characteristics of multiple nodule tracheobronchial abnormalities found under bronchoscopy caused by different diseases. METHODS Eighty-seven patients with multiple tracheobronchial nodules were enrolled in this study. The characteristics of the multinodule lesions and the patient were diagnosed based on the pathology findings in our hospital. Chest computed tomography images were retrospectively reviewed by pulmonologists and radiologist. RESULTS In 55 patients with definite pathological diagnosis, 16 (29%) patients were diagnosed as tuberculosis (TB) granuloma; 23 (41.8%) cases were diagnosed as malignant disease; 12 (21.8%) cases were diagnosed as tracheobronchopathia osteochondroplastica; 2 (3.6%) cases were diagnosed as sarcoidosis; and one case (1.8%) was diagnosed as lymphoma and one case (1.8%) as fungal infection. There were 32 cases of chronic inflammation. There was no relationship between nodule distribution and the pathological diagnosis. Malignant nodules usually smaller with a pale outlook, while nodules with larger size and smooth and intact mucosa usually turn out to be granuloma of unknown reason. CONCLUSION The major causes of mutinodule lesions observed using bronchoscopy are tumor and TB. The presence of multiple endotracheobronchial nodules suggest that pulmonary lesion is present, and biopsy should be performed. Malignant nodules can be diagnosed by appearance and biopsy. Pathology results of TB, sarcoidosis and fungal infection can turn out to be granuloma of unknown reason. Further diagnosis needs other clinical materials.

Abstract
Endotracheal tuberculosis (ETTB) is an infrequent form of tuberculosis whose major feature is the infection of the tracheobronchial tree by Mycobacterium tuberculosis. This case presents a 73-year-old man admitted to our hospital with fatigue, weakness, dry cough and weight loss. His chest X-ray was normal but the high resolution computed tomography (HRCT) showed normal parenchyma images with mediastinal and hilar lymphadenopathy. There was inflammation of the tracheal wall and infiltrates in pavement epithelium; however, the tracheal biopsy for acid-fast bacilli was negative. He was finally diagnosed by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) of the lymph nodes. Four drugs were prescribed and symptoms improved. EBUS-TBNA contributed to prompt diagnosis. The patient was treated and evolved without complications, such as tracheal stenosis.

Abstract
BACKGROUND AND AIMS Early diagnosis and treatment of central nervous system tuberculosis are important because of high mortality and morbidity. Airways must be carefully evaluated in differential diagnosis. METHODS We present a rare case of intracranial-endobronchial tuberculosis mimicking lung cancer with brain metastasis. RESULTS A vegetative mass lesion, confirmed as necrotic granulomatous inflammation, originating from the entrance of the right upper lobe entry, was coagulated and extracted by argon plasma coagulation and cryotherapy to prevent permanent upper lobe atelectasis. Mycobacterium tuberculosis complex was detected in bronchoscopic material. A four-drug initial anti-tuberculous treatment regimen was given in 2 months. The upper lobe atelectasis was resolved at the fourth month of therapy despite upper lobar bronchus patency. The patient was doing well and completed the two-drug maintenance therapy of 7 months with complete resolution. CONCLUSION In such cases, tissue diagnosis should be achieved as early as possible and anti-tuberculous treatment was commenced along with advanced interventional techniques.
