[PMID: 39061098 PMCID: PMC11282832 DOI: 10.1186/s13019-024-02972-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Accepted: 07/13/2024] [Indexed: 07/28/2024] Open
Abstract
BACKGROUND Pleural effusion caused by fibrosing mediastinitis is rarely reported. This study aimed to summarize the clinical manifestations, diagnosis and treatment of transudative pleural effusion due to fibrosing mediastinitis. METHODS Medical records and follow-up data of 7 patients with transudative pleural effusion due to fibrosing mediastinitis in Beijing Chaoyang Hospital between May 2014 and Feb 2018 were retrospectively analyzed. RESULTS These patients included 4 males and 3 females, with an average age of (64 ± 9) years. There were 3 left-sided effusions, 2 right-sided effusions and 2 bilateral effusions. Previous or latent tuberculosis was found in 6 patients. Pulmonary hypertension was indicated by echocardiography in all the 7 patients. Computed tomography pulmonary angiography (CTPA) of all the 7 cases showed increased soft tissue images visible in the mediastinum and bilateral hilus, different degrees of stenosis or occlusion in the pulmonary artery and pulmonary vein. In addition, 4 cases were found of right middle lobe atelectasis with a mediastinal window setting. There was interstitial pulmonary edema on the side of pleural effusion with a lung window setting. All the 7 patients were treated with intermittent drainage of pleural effusion combined with diuretic therapy. Five patients were treated with antituberculosis therapy. Up to now, two patients died of right heart failure and respiratory failure after 2 and 16 months respectively; The remaining 5 patients were still in follow up. CONCLUSION Fibrosing mediastinitis can lead to pulmonary vein stenosis or occlusion, and thus cause transudative pleural effusion, which can be detected by CTPA. Pulmonary hypertension, long time of cough, and a history of tuberculosis are common in these patients. The common therapy is intermittent drainage of pleural effusion combined with diuretic therapy.

Abstract
Fibrosing mediastinitis (FM) is a heterogeneous disease characterized by sclerosing fibrosis of mediastinal structures. Pulmonary hypertension (PH) may complicate the course of the disease and can contribute significantly to the morbidity of FM. Due to the rarity and complexity of the disease, evidence-based guidelines are not currently available, and the optimal treatment approach is unknown. Management approaches should be individualized, and current techniques are often unsatisfactory. Here, we present two cases of PH complicating FM that were managed using pulmonary artery vasodilator therapy with excellent hemodynamic response.

Abstract
Fibrosing mediastinitis (FM) is a rare, potentially progressive disease resulting from an idiosyncratic immune response to a variety of stimuli that lead to fibrous infiltration of the mediastinum and possible narrowing of the bronchovascular structures. We report an unusual case of FM in a pediatric patient presenting as myopericarditis and progressing to pericardial thickening and encasement of the mediastinal vascular structures needing surgical intervention. Imaging, including transthoracic echocardiography, cardiac computed tomography, and cardiac magnetic resonance played a crucial role in the diagnosis, assessment, and follow-up. Contrast-enhanced computed tomography can be especially helpful to demonstrate potential findings associated with FM.

Abstract
Aims This study aims to develop a scoring system for evaluating the degree of pulmonary vascular stenosis in fibrosing mediastinitis (FM). Methods and results A retrospective single-centre study was conducted on 56 patients with FM in China between April 2014 and August 2021. The involvement of pulmonary vessels in patients with FM was assessed using dual-phase computed tomography pulmonary angiography, and we found that 85.7% of the patients had both pulmonary artery (PA) and vein (PV) involvement. PA involvement was mainly located proximal to both the upper PA and the bilateral basal trunk levels in the lower lungs. The involvement of the superior PV was more common than that of the inferior PV, and the right inferior PV was the least involved. Most of these lesions exhibited moderate or severe stenosis. Additionally, a scoring system for evaluating the degree of pulmonary vascular stenosis was developed. A correlation analysis revealed a negative correlation between the final pulmonary vascular score and the pulmonary arterial pressure, pulmonary vascular resistance, and maximum tricuspid regurgitation velocity. The calculated score of 17.1 was the best cut-off value for the diagnosis of mild and severe pulmonary hypertension (PH). Conclusion We successfully developed a scoring system for pulmonary vascular stenosis that can be used to evaluate the severity of pulmonary vessel involvement and PH. This scoring system may be relevant in the future development of target-based strategies for percutaneous interventions.

Abstract
Fibrosing mediastinitis, also known as sclerosing mediastinitis, is an uncommon condition marked by abnormal proliferation of fibrous tissue in the mediastinum. This condition may accrue either as an idiopathic condition or as a complication of an underlying disease process. Its pathogenesis remains unknown. However, most reported cases are incriminating abnormal immune-mediated hypersensitivity responses to Histoplasma infection. Other rare causes include tuberculosis, blastomycosis, and an idiopathic form that may be associated with other miscellaneous conditions. CT and MR imaging play a vital role in the diagnosis and management of this disease. We present a rare case of fibrosing mediastinitis as a late complication of tuberculosis in a 34-year-old man with a prior history of mediastinal tuberculosis, mimicking initially a neoplastic mediastinal process. We will describe this clinical case in the light of the literature and point out the contribution of radiological imaging in the diagnosis of this rare pathology.

Abstract
Pulmonary hypertension (PH) is a progressive and severe disorder in pulmonary hemodynamics. PH can be fatal if not well managed. Fibrosing mediastinitis (FM) is a rare and benign fibroproliferative disease in the mediastinum, which may lead to pulmonary vessel compression and PH. PH caused by FM (PH-FM) is a pathologic condition belonging to group 5 in the World Health Organization PH classification. PH-FM has a poor prognosis because of a lack of effective therapeutic modalities and inappropriate diagnosis. With the development of percutaneous pulmonary vascular interventional therapy, the prognosis of PH-FM has been greatly improved in recent years. This article provides a comprehensive review on the epidemiology, pathophysiologic characteristics, clinical manifestations, diagnostic approaches, and treatment modalities of PH-FM based on data from published reports and our medical center with the goal of facilitating the diagnosis and treatment of this fatal disease. PH-FM, as a type of rare condition in group 5 PH, has a poor prognosis because of a lack of effective therapeutic modalities and frequent misdiagnosis and underdiagnosis. The most prevalent trigger of FM is H-FM in the United States and TB-FM in China. Imaging findings, including mismatched perfusion defects in the V/Q scan, FM dyad, and FM triad are important diagnostic clues, and clinical classification facilitates decision making in diagnosis and therapeutics. Because of the limited efficacy of drug therapy as well as the uncertain effectiveness and high risk of surgical treatment, endovascular interventional modality is currently the preferred therapeutic option, although procedure-related complications and intrastent restenosis after PV intervention need to be addressed.

Abstract
Fibrosing mediastinitis (FM) is an uncommon diagnosis that involves the proliferation of extensive, dense fibrous tissue in the mediastinum. FM accounts for less than 1% of people with prior infection by Histoplasma capsulatum that develop hypersensitivity immune responses to antigens released during the initial exposure. Other causes include tuberculosis, blastomycosis, sarcoidosis, radiation, and idiopathic. We describe FM presenting with superior vena cava (SVC) syndrome. A 66-year-old Caucasian male presented with a one-week history of progressively worsening facial swelling associated with dysphonia, bilateral ptosis, dyspnea on exertion, and unintentional weight loss of 30 pounds within the past three months. He had a 40-pack-year smoking history and a past medical history of essential hypertension, peripheral vascular disease, and bilateral internal carotid artery stenosis. The CT chest demonstrated non-specific soft tissue extending throughout the mediastinum and towards the right hilar region, complicated by severe attenuation of the superior vena cava and a 2.4 cm × 1.6 cm necrotic lymph node. The mediastinum had hyperemic and desmoplastic changes heavily encased in venous collaterals. L4 lymph node pathological evaluation demonstrated sinus histiocytosis and reactive lymphoid hyperplasia without signs of malignancy or atypia. The patient was treated with corticosteroid and diuretic therapy to achieve intermittent symptomatic relief, but continued to decline clinically, ultimately leading to his demise. The diagnosis of FM is best obtained through CT chest with intravenous contrast to demonstrate abnormal mediastinal tissue and possible structural compromise. A biopsy of the mediastinal tissue may also help rule out malignancy. Only a few case reports have demonstrated mixed symptomatic and radiologic responses to anti-inflammatory and/or antifungal treatment. Even non-surgical and surgical interventions have shown inconsistent efficacy, with frequent restenosis warranting re-exploration.

Abstract
Fibrosing mediastinitis (FM) is a rare fibroinflammatory disease of the mediastinum with an etiology and clinical features that vary by world region. The characteristics of FM in Japan are still unknown. We herein report two Japanese patients with FM who were treated with corticosteroids and responded well. We also reviewed the Japanese literature on PubMed® and summarized the characteristics of 27 Japanese FM patients, including our two patients. In Japan, the predominant cases were those without a specific cause, were diffusely distributed, and responded well to corticosteroid therapy.

Abstract
Fibrosing mediastinitis (FM) is a progressive, life-threatening disease
characterized by extrinsic compression of mediastinal bronchovascular
structures, and the clinical manifestations largely depend upon the
affected structures. Pleural effusion is rarely reported in patients
with FM. We herein describe a 70-year-old man who presented with
recurrent breathlessness and refractory left pleural effusion. He was
misdiagnosed with and treated for tuberculous pleurisy for several
months. Thoracentesis revealed a transudative pleural effusion, and a
contrast-enhanced computed tomography scan of the thorax showed an
extensive mediastinal soft tissue mass consistent with FM. Pulmonary
angiography demonstrated pulmonary artery stenosis on the right side
and pulmonary vein stenosis mainly on the left side. After measurement
of the pulmonary arterial pressure by right heart catheterization, the
patient was diagnosed with pulmonary hypertension associated with FM.
He underwent balloon angioplasty and stent implantation of the
stenosed pulmonary vessels, which led to long-term improvement in his
breathlessness and pleural effusion. Our systematic review of the
literature highlights that pleural effusion can be an uncommon
complication of FM and requires careful etiological
differentiation.

Abstract
Although fibrotic disorders are frequently assumed to be linked to TH2 cells, quantitative tissue interrogation studies have rarely been performed to establish this link and certainly many fibrotic diseases do not fall within the type 2/allergic disease spectrum. We have previously linked two human autoimmune fibrotic diseases, IgG4-related disease and systemic sclerosis, to the clonal expansion and lesional accumulation of CD4+CTLs. In both these diseases TH2 cell accumulation was found to be sparse. Fibrosing mediastinitis linked to Histoplasma capsulatum infection histologically resembles IgG4-related disease in terms of the inflammatory infiltrate and fibrosis, and it provides an example of a fibrotic disease of infectious origin in which the potentially profibrotic T cells may be induced and reactivated by fungal Ags. We show in this study that, in this human disease, CD4+CTLs accumulate in the blood, are clonally expanded, infiltrate into disease lesions, and can be reactivated in vitro by H. capsulatum Ags. TH2 cells are relatively sparse at lesional sites. These studies support a general role for CD4+CTLs in inflammatory fibrosis and suggest that fibrosing mediastinitis is an Ag-driven disease that may provide important mechanistic insights into the pathogenesis of idiopathic fibrotic diseases.

Abstract
PURPOSE Fibrosing mediastinitis is a rare disease characterized by fibrosis of mediastinal structures with subsequent constriction of the bronchi and pulmonary vessels leading to potential respiratory compromise and death. Presently, there is no effective curative treatment with available treatments focused on reducing symptomology, including placement of pulmonary artery stents. Limited studies examine the use of stents in fibrosing mediastinitis. Given this knowledge gap, we assessed stent patency, hemodynamics, complications, and secondary outcomes of clinical improvement of pulmonary artery stenting for fibrosing mediastinitis. MATERIALS AND METHODS Nine patients with fibrosing mediastinitis and pulmonary artery stents were retrospectively identified for inclusion (six females, three males; mean age 44.17 years, range 13-68; total 13 primary stents) from 2005 to 2018. Eight patients had history of PH. All patients had dyspnea on presentation. Seven patients had ventilation/perfusion studies demonstrating impairment. Results from computed tomography and echocardiography studies were collected to assess patency and physiologic response. RESULTS All patients received initial angioplasty and stenting of the right pulmonary artery (10 stents). Two patients underwent additional left-sided intervention (3 stents). Stenting significantly increased lesion luminal patency (54-79%; P < 0.005) and reduced systolic pressure gradients across stenoses (mean -9.38 mmHg; P < 0.005). Primary patency at one year was 90%. Two stents received reintervention at 276 and 497 days. 89% reported improvement in dyspnea in the initial post-stenting period. There were no mortalities or major complications. CONCLUSION Pulmonary artery stenting improves vascular patency and provides symptomatic relief in patients with fibrosing mediastinitis.

Abstract
Fibrosing mediastinitis (FM) is a very rare disease, often caused by histoplasmosis capsulatum, tuberculosis, sarcoidosis, autoimmunity and other diseases, such as IgG 4-related diseases. Fibrous structures in the mediastinum compress the pulmonary artery, pulmonary vein, superior vena cava, esophagus, trachea and cardiac vessels, leading to clinical symptoms. Drug therapeutic modality for pulmonary vein stenosis (PVS) caused by FM is palliative in essence and with limited efficacy, whereas surgical treatment causes high mortality. In recent years, catheter-based treatment to FM-caused PVS has emerged as a promising therapeutic modality, however, the safety and effectiveness of this modality remain unclear. Therefore, a systematic review on the safety and efficacy of the catheter-based treatment for PVS caused by FM was performed, in the hope to shed lights on the alternative therapeutic strategy to this fatal disease.

Abstract
Fibrosing lesions of the mediastinum represent a small but challenging group of lesions that range in etiology from infectious to idiopathic to neoplastic. The diagnosis of such lesions becomes more challenging in the setting of mediastinoscopic biopsies. In addition, over the years, there has been further accumulation of knowledge of the clinical aspects of these lesions that needs to be incorporated into their evaluation. Therefore, it is essential that in the general evaluation of these fibrosing processes, one not only carefully examines the histopathologic features of the lesion, that of a fibroinflammatory process with the appropriate histochemical and immunohistochemical studies, but also carefully evaluates the clinical presentation and imaging findings. Needless to say, as will be illustrated in this review, determining a definitive unequivocal diagnosis on a small mediastinoscopic biopsy may be difficult, and often one needs to provide guidance on the perspective of the histologic features present. In some cases, mainly tumoral conditions with extensive fibrosis, a conclusive diagnosis can be made; however, it is those cases in which the extensive fibrosis is the only histopathologic feature where more appropriate guidance is required. While this review will focus more on the non-neoplastic fibroinflammatory lesions of the mediastinum, within the discussion of differential diagnoses, we will discuss some neoplastic conditions that commonly show extensive fibrosing features.

Abstract
Sclerosing mediastinitis (SM), previously named chronic fibrosing mediastinitis,
is an inflammatory process that in its end-stage results to sclerosis around the
mediastinal structures. SM is quite rare and has been correlated with
inflammatory and autoimmune diseases, as well as malignancy. SM may either
present in a mild form, with minor symptoms and a benign course or in a more
aggressive form with severe pulmonary hypertension and subsequent higher
morbidity and mortality. The diagnosis of SM may be difficult and quite
challenging, as symptoms depend on the mediastinal structure that is mainly
involved; quite often the superior vena cava. However, practically any
mediastinal structure may be involved by the fibrotic process, such as the
central airways, as well as the pulmonary arteries and veins, leading to
obstruction or total occlusion. The latter may be impossible to undergo proper
surgical excision of the lesion, and is considered to be a real challenge to the
surgeon. We herein report a case of SM that presented with arterial and venous
compression. The imaging appearance was that of unilateral pulmonary edema,
associated with lung collapse. The case is supplemented by a non-systematic
review of the relevant literature.

Abstract
Fibrosing mediastinitis is a rare, often debilitating and potentially lethal disease characterized by an exuberant fibroinflammatory response within the mediastinum. Patients typically present with insidious symptoms related to compression of adjacent structures including the esophagus, heart, airways, and cardiac vessels. Fibrosing mediastinitis is most often triggered by Histoplasmosis infection; however, antifungal and anti-inflammatory therapies are largely ineffective. While structural interventions aimed at alleviating obstruction can provide significant palliation, surgical interventions are challenging with high mortality and clinical experience with percutaneous interventions is limited. Here, we will review the presentation, natural history, and treatment of fibrosing mediastinitis, placing particular emphasis on catheter-based therapies.

Abstract
Fungal infections of the lung are common in endemic areas and in immunocompromised patients. Antifungal therapy is the cornerstone of medical therapy for most pulmonary fungi but surgery is an important adjunct in cases of complicated disease or resistant organisms. A multidisciplinary approach including pulmonary medicine, infectious disease, interventional radiology, and thoracic surgery is favored. This article reviews the surgical management of common fungal pulmonary infections and their sequelae.

Abstract
PURPOSE Fibrosing mediastinitis (FM) is a rare disorder characterized by an excessive fibrotic reaction within the mediastinum, which can result in compression of mediastinal structures. To investigate the clinical and imaging characteristics of TB-associated FM, patients with evidence of TB infection were retrospectively evaluated in this study. MATERIALS AND METHODS A total of 33 patients with clinically diagnosed FM and evidence of TB infection were selected from the database of two institutional medical centers. Medical records were reviewed to evaluate the clinical disease spectrum, responses to therapy and imaging characteristics. RESULTS TB-associated FM showed distinctive infiltrative pattern on chest CT, such as bilateral involvement and hilar predominance. The majority of patients presented with nonspecific respiratory symptoms due to the compression of mediastinal broncho-vascular structures. Echocardiography discovered pulmonary hypertension to various degrees in 60% of patients. Although only a part of patients responded to medical therapy, they seldom showed deterioration during the follow-up. CONCLUSIONS TB-associated FM shows some specific imaging characteristics, reflecting immune-mediated fibrotic reaction secondary to TB infection. The insidious progression to mediastinal fibrosis after TB infection poses a challenge to the early diagnosis and results in subsequent respiratory dysfunction and pulmonary hypertension.

Abstract
Mediastinitis continues to be an important and life-threatening complication after median sternotomy despite advances in prevention and treatment strategies, with an incidence of 0.25-5%. It can also occur as extension of infection from adjacent structures such as the oesophagus, airways and lungs, or as descending necrotizing infection from the head and neck. In addition, there is a chronic form of 'chronic fibrosing mediastinitis' usually caused by granulomatous infections. In this expert consensus, the evidence for strategies for treatment and prevention of mediatinitis is reviewed in detail aiming at reducing the incidence and optimizing the management of this serious condition.

Abstract
Objectives: Subglottic stenosis is an abnormal narrowing of the tracheal lumen at the level of subglottis (the area in between the vocal cords and the cricoid cartilage). It can cause significant symptoms due to severe attenuation of airflow. We describe our experience in alleviating symptoms by addressing the stenosis using fibreoptic bronchoscopic methods. Methods: We report all concurrent cases performed between September 2015 and July 2016. We use a combination of balloon dilation, electro-surgery knife to dilate and incise stenotic segments followed by steroid injection to modulate healing. Results: We treated 10 patients in the study period, 8 of which were women. A total of 39 procedures were performed on these patients during this period. Gastro-esophageal reflux was the most common comorbidity associated with stenosis. The majority of the patients required more than 2 therapeutic procedures, but none required more than 4 procedures. There were no complications. Conclusion: Tracheal stenosis and in particular subglottic stenosis is a recurrent process and its management requires extensive collaboration amongst treating specialties. Our technique of steroid injection after dilation of the stenosis was effective in symptom control and decreased the number of repeat procedures.

Abstract
Fibrosing mediastinitis (FM) is a rare disease where there is thickening of the fibrous tissue in the mediastinum. While histoplasmosis is the the most common recognised cause, the link with tuberculosis (TB) has been rarely documented. We review the link between TB and FM, and describe a case of probable TB-related FM.Our case is of a 74-year-old man who presented with breathlessness 3 years after fully treated TB. Scans revealed a calcified soft tissue mass within the mediastinum, and a diagnosis of fibrosing mediastinitis resulting in pulmonary hypertension was made. Tests for histoplasmosis and IgG4 staining were negative. Surgical intervention was not felt to be beneficial, and he was treated with prednisolone and mycophenolate mofetil.In the review, we highlight the two forms of mediastinitis—granulomatous versus fibrous, and how these two entities may be on a spectrum of disease progression. We also explore the prevalence, clinical presentation, pathogenesis, imaging techniques and treatment options of TB-related FM.

Abstract
Background: Fibrosing mediastinitis (FM) is a rare disease. FM is thought to be related to prior granulomatous mediastinal infection, such as histoplasmosis or tuberculosis. The majority of cases have been reported in endemic regions for histoplasmosis. The characteristics of cases of FM in China, where the prevalence of tuberculosis is high, have not been reported. We analyzed the clinical, imaging, and bronchoscopic features of Chinese patients with FM to promote awareness of this disease. Methods: Between January 2005 and June 2015, twenty patients were diagnosed with FM in our hospital. Medical records and follow-up data were collected. Imaging and biopsy findings were reviewed by radiologists and pathologists. Results: A total of 20 patients were analyzed (8 males and 12 females). The age ranged from 43 to 88 years with a mean age of 69.5 years. Previous or latent tuberculosis was found in 12 cases. Clinical symptoms included dyspnea (18/20), cough (17/20), expectoration (7/20), and recurrent pneumonia (3/20). Chest computed tomography scans showed a diffuse, homogeneous, soft tissue process throughout the mediastinum and hila with compression of bronchial and pulmonary vessels. Calcification was common (15/20). Pulmonary hypertension was present in 9 of 20 cases. Diffuse black pigmentation in the bronchial mucosa was frequently seen on bronchoscopy (12/13). The patients’ response to antituberculosis treatment was inconsistent. Conclusions: FM in Chinese patients is most likely associated with tuberculosis. Some characteristics of FM are different from cases caused by histoplasmosis.

Abstract
Fibrosing mediastinitis (FM), also known as sclerosing mediastinitis, is an uncommon but serious disease involving the mediastinal structures. A high index of suspicion is essential to establish the diagnosis of FM and starting the appropriate therapy for patients. Here, we report a case of a young female who presented with chest symptoms and subsequently underwent different laboratory and radiologic investigations and an excisional biopsy. The findings of these investigations were consistent with the diagnosis of idiopathic FM. Her disease was associated with complete occlusion of three pulmonary veins and the left main pulmonary artery. The patient was treated with initial high-dose steroids followed by maintenance steroid and methotrexate therapy with very good long-term disease control. Clinical response, high-sensitivity C-reactive protein, and erythrocyte sedimentation rate were used to monitor disease activity and response to therapy.

Abstract
Fibrosing mediastinitis is a rare condition defined by the presence of fibrotic mediastinal infiltrates that obliterate normal fat planes. It is a late complication of a previous granulomatous infection, such as histoplasmosis or tuberculosis (TB). Due to its rarity, fibrosing mediastinitis is often under-recognized, and the clinical presentation is variable and dependent on the extent of infiltration or encasement of structures within the mediastinum. We present a case of fibrosing mediastinitis in a man with a prior history of TB, who presented with progressive dyspnea and was found to have chronic mediastinal soft tissue opacities and pulmonary hypertension. His diagnosis was delayed due to the lack of recognition of this clinical/radiographic entity. Fibrosing mediastinitis is a rare entity usually caused by granulomatous disease. Most cases develop as a late complication of histoplasmosis or TB. The presence of calcified mediastinal soft tissue infiltrates on advanced chest imaging can be diagnostic of fibrosing mediastinitis in patients with a prior history of a granulomatous infection once active processes such as malignancy are excluded.

Abstract
BACKGROUND Chronic mediastinitis is a rare disorder characterized by the proliferation of fibrous tissue within the mediastinum resulting in compression of mediastinal structures. OBJECTIVE This article gives an overview of the treatment options for chronic mediastinitis. MATERIAL AND METHODS A literature search was carried out regarding treatment options for chronic mediastinitis RESULTS AND CONCLUSION Little is known about the pathogenesis of chronic mediastinitis, which has hampered the development of novel therapeutic approaches. There is no convincing evidence for the success of medicinal (antifungal or conventional anti-inflammatory) therapy and it is not recommended. In cases of clinical symptoms procedures for decompression, such as endovascular or endobronchial stents or surgical procedures, such as decompression interventions or extra-anatomic bypasses should be considered. The prognosis for unilateral involvement is better than for bilateral involvement if performed in specialized centers.

Abstract
Introduction Fibrosing mediastinitis (FM) is a rare but fatal disease characterized by an excessive fibrotic reaction in the mediastinum, which can lead to life-threatening stenosis of the pulmonary veins (PV). Catheter-based intervention is currently the only viable option for therapy. However, the current literature on how best to manage these difficult cases, especially in regards to sequential interventions and their potential complications is very limited. Methods We searched through a database of all patients who have undergone PV interventions at the Earl H. Wood Cardiac Catheterization Laboratory in Mayo Clinic, Rochester. From this collection, we selected patients that underwent PV intervention to relieve stenosis secondary to FM. Results Eight patients were identified, with a mean age of 41 years (24–59 years). Five were men, and three were women. Three patients underwent balloon angioplasty alone, and five patients had stents placed. The majority of patients had acute hemodynamic and symptomatic improvement. More than one intervention was required in five patients, four patients had at least one episode of restenosis, and four patients died within four weeks of their first PV intervention. Conclusions We describe the largest reported case series of catheter-based intervention for PV stenosis in FM. Although catheter-based therapy improved hemodynamics, short-term vascular patency, and patient symptoms, the rate of life-threatening complications, restenosis, and mortality associated with these interventions was found to be high. Despite these associated risks, catheter-based intervention is the only palliative option available to improve quality of life in severely symptomatic patients with PV stenosis and FM. Patients with PV stenosis and FM (especially those with bilateral disease) have an overall poor prognosis in spite of undergoing these interventions due to the progressive and recalcitrant nature of the disease. This underscores the need for further innovative approaches to manage this disease.

Abstract
Pulmonary histoplasmosis is generally a self-limited respiratory illness in endemic areas. Fibrosing mediastinitis is a severe chronic complication of pulmonary histoplasmosis in which pulmonary vessels and airways can be compressed with the potential for life-threatening implications. We present a 50-year-old male patient who presented with a total occlusion of the left pulmonary artery due to fibrosing mediastinitis.

Abstract
PURPOSE To evaluate the safety and clinical effectiveness of fluoroscopically guided balloon dilation in patients with benign bronchial stricture occurring after radiotherapy (RT). METHODS From March 2002 to January 2013, ten patients with benign bronchial stricture occurring after RT underwent fluoroscopically guided balloon dilation as their initial treatment. Technical success, primary and secondary clinical success, improvement in respiratory status, and complications were evaluated. The symptomatic improvement period was calculated. RESULTS A total of 15 balloon dilation sessions were performed in ten patients, with a range of 1-4 sessions per patient (mean 1.5 sessions). Technical success was achieved in 100 %. Six of the ten patients exhibited no symptom recurrence and required no further treatment until the end of follow-up (range 4-105 months). Four patients (40 %) experienced recurrent symptom, and two of four patients underwent repeat balloon dilations. The remaining two patients underwent cutting balloon dilation and temporary stent placement, respectively, and they exhibited symptom improvement after adjuvant treatment until the end of our study. Finally, primary clinical success was achieved in six of ten patients (60 %) and secondary clinical success was achieved in eight of ten patients (80 %). The mean symptom improvement period was 61.9 ± 16 months (95 % confidence interval 30.6-93.3). CONCLUSION Fluoroscopically guided balloon dilation seems to be safe and clinically effective for the treatment of RT-induced benign bronchial stricture. Temporary stent placement or cutting balloon dilation could be considered in patients with benign bronchial strictures resistant to fluoroscopically guided balloon dilation.

Abstract
Fibrosing mediastinitis is rare. One type of this disease is idiopathic fibrosing mediastinitis. It is necessary to rule out malignancy in order to accurately diagnose fibrosing mediastinitis. We herein report a case of anaplastic large cell lymphoma diagnosed three months after a preliminary diagnosis of fibrosing mediastinitis. Glucocorticoid therapy was not successful in controlling disease progression. Immediately after initiating chemotherapy for lymphoma, the patient's symptoms improved dramatically and the mediastinal lesion decreased in size. Although few similar cases have been reported, hidden malignancy may present as fibrosing mediastinitis. Therefore, physicians should consider the probability of malignancy in patients with fibrosing mediastinitis because treatments may vary accordingly.

Abstract
Fibrosing mediastinitis (FM) is a rare disorder characterized by the invasive proliferation of fibrous tissue within the mediastinum. FM frequently results in the compression of vital mediastinal structures and has been associated with substantial morbidity and mortality. Its pathogenesis remains unknown. However, in North America most cases are thought to represent an immune-mediated hypersensitivity response to Histoplasma capsulatum infection. To characterize the clinical disease spectrum, natural disease progression, responses to therapy, and overall survival, we retrospectively analyzed all 80 consecutive patients with a diagnosis of FM evaluated at Mayo Clinic, Rochester, MN, from 1998 to 2007. Furthermore, we characterized the adaptive immune response in 15 representative patients by immunohistochemistry. The majority of patients presented with nonspecific respiratory symptoms due to the compression of mediastinal broncho-vascular structures. Chest radiographic imaging most frequently revealed localized, invasive, and frequently calcified right-sided mediastinal masses. Most patients had radiographic or serologic evidence of previous histoplasmosis. In contrast to earlier reports summarizing previously reported FM cases, the clinical course of our patients appeared to be more benign and less progressive. The overall survival was similar to that of age-matched controls. There were only 5 deaths, 2 of which were attributed to FM. These differences may reflect publication bias associated with the preferential reporting of more severely affected FM patients in the medical literature, as well as the more inclusive case definition used in our consecutive case series. Surgical and nonsurgical interventions effectively relieved symptoms caused by the compression of mediastinal vascular structures in these carefully selected patients. In contrast, antifungal and antiinflammatory agents appeared ineffective. Histologic examination and immunostaining revealed mixed inflammatory infiltrates consistent with a fibroinflammatory tissue response in these histoplasmosis-associated FM cases. The immune cell infiltrates included large numbers of CD20-positive B lymphocytes. As B lymphocytes may contribute to the pathogenesis of the disease, therapeutic B-cell depletion should be investigated as a therapeutic strategy for FM.

Abstract
BACKGROUND Fibrosing Mediastinitis (FM) is a rare complication of infection with Histoplasma capsulatum that can lead to obstruction of pulmonary and systemic vasculature and large airways, often resulting in significant morbidity and mortality. Medical therapy is ineffective, and surgical intervention is often not feasible. Stent implantation offers a potential treatment for vascular obstruction due to FM, but this has not been well studied. METHODS AND RESULTS We conducted a retrospective review of all patients undergoing cardiac catheterization for FM. Anatomic site of stenosis and hemodynamic information before and after intervention, as well as clinical presentation and follow-up data, were recorded. From 1996 to 2008, 58 patients underwent cardiac catheterization for FM, with intervention performed in 40 (69%). A total of 77 stents were used to relieve 59 lesions (pulmonary artery=26, pulmonary vein=21, and superior vena cava=12). Significant reduction in pressure gradients (P<0.001) and increase in vessel caliber (P<0.001) were seen at all locations. Symptomatic recurrent stenosis requiring further intervention occurred in 11 patients (28%). Median time to recurrence was 115 months. Thirty-two (87%) of 37 patients for whom follow-up was available reported symptomatic improvement after stent placement. PROCEDURE related complications occurred in 14 patients (24%). Overall mortality was 19%, with the majority of deaths in patients with bilateral disease. Among patients with bilateral disease, intervention was associated with improved survival at 5 years. CONCLUSION Percutaneous vascular stent implantation is an effective therapy for central vascular obstruction due to FM, providing significant relief of anatomic obstruction and sustained clinical improvement.

Abstract
Cutting balloon angioplasty is a common treatment modality in the pediatric population for pulmonary artery stenosis. We present an adult with histoplasmosis induced fibrosing mediastinitis resulting in pulmonary artery stenosis that was successfully treated with cutting balloon angioplasty and subsequent stent deployment. Percutaneous endovascular stent placement has be shown to effectively alleviate pulmonary artery stenosis, however in-stent restenosis does limit durability. Pharmacologic therapy is indicated with either mediastinal adenitis or mediastinal granuloma with anti-fungal agents such as amphotericin B and itraconazole. Surgical intervention for histoplasmosis induced fibrosing mediastinitis is rarely indicated and may result in fatal complications that stem from mediastinal fibrosis due to resultant destruction of surgical planes. To our knowledge, this is the first reported case of utilizing cutting balloon angioplasty and stent insertion for the treatment of histoplasmosis induced fibrosing mediastinitis complicated by pulmonary artery stenosis.

Abstract
CONTEXT Not uncommonly, a surgical pathologist will be requested to review excised material, with a clinical diagnosis of cancer, in which no malignancy can be identified. Often, sampling may be the issue. However, different nonneoplastic processes may mimic cancer clinically and not be recognized histologically. These are commonly referred to as pseudoneoplasms and can involve the lung, pleura, and mediastinum. OBJECTIVE To review the most commonly encountered pseudoneoplasms of the thoracic cavity in surgical pathology and discuss the main differential diagnosis. DATA SOURCES Literature and personal review of cases with focus on inflammatory pseudotumors of the lung, organizing pneumonia, nodular lymphoid hyperplasia, apical cap, round atelectasis, and sclerosing mediastinitis with its pulmonary counterpart, hyalinizing granuloma. CONCLUSIONS When reviewing specimens that appear nondiagnostic for malignancy, it is important to consider one of these pseudoneoplasms in the differential diagnosis as they may explain the clinical and radiologic information.

Abstract
BACKGROUND Fibrosing mediastinitis is a rare disease characterized by an excessive fibrotic reaction in the mediastinum, which may entrap mediastinal structures including the pulmonary arteries. Our objectives were to assess the surgical strategies and outcomes of repair of pulmonary artery occlusion attributable to mediastinal fibrosis. METHODS With approval from the Mayo Clinic Institutional Review Board, we identified all patients with fibrosing mediastinitis who underwent an operation for relief of pulmonary artery obstruction between 1980 and 2008. Perioperative data were collected using medical records and late follow-up surveys. RESULTS Operative procedures to bypass or reconstruct an obstructed pulmonary artery were performed in 5 patients. Patients' median age was 40 years (range, 27 to 51 years), and all patients were symptomatic and had right ventricular hypertension. In 3 patients, a double-outlet right ventricle was constructed using a valved conduit (porcine valved conduit, n = 1; aortic homograft, n = 2) from the right ventricle to the right pulmonary artery. Two patients required complete reconstruction of the pulmonary artery confluence using a pulmonary homograft in 1 patient and a hybrid technique of autologous pericardial reconstruction and intraoperative stenting in another patient. All patients had a reduction in right ventricular pressures after operation. One patient died perioperatively owing to respiratory failure; the remaining 4 patients were alive at a median follow-up of 7.4 years (range, 0.5 to 14.7 years). One patient required late balloon dilatation of the conduit and distal pulmonary arteries 10 years after initial operation, but the remaining conduits were widely patent at late follow-up. Late functional improvement was limited owing to other complications from mediastinal fibrosis or other comorbidities. CONCLUSIONS Treatment of pulmonary artery occlusion attributable to mediastinal fibrosis can be challenging. Successful operative strategies include both creation of a double-outlet right ventricle and complete reconstruction of the pulmonary artery confluence. Hybrid techniques of both conduit placement and stenting should also be considered for patients with occluded pulmonary arteries.

Abstract
AbstractEvidence-based guidelines for the management of patients with histoplasmosis were prepared by an Expert Panel of the Infectious Diseases Society of America. These updated guidelines replace the previous treatment guidelines published in 2000 (Clin Infect Dis 2000; 30:688–95). The guidelines are intended for use by health care providers who care for patients who either have these infections or may be at risk for them. Since 2000, several new antifungal agents have become available, and clinical trials and case series have increased our understanding of the management of histoplasmosis. Advances in immunosuppressive treatment for inflammatory disorders have created new questions about the approach to prevention and treatment of histoplasmosis. New information, based on publications from the period 1999–2006, are incorporated into this guideline document. In addition, the panel added recommendations for management of histoplasmosis in children for those aspects that differ from aspects in adults.
