Association of tibial osteomyelitis and pneumonitis due to miliary tuberculosis in a patient with systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease, which has great prevalence and uncommon manifestations of opportunistic infectious diseases, mainly due to the multiple abnormalities of the immune system and the immunosuppressive effect of the medications used in its treatment. Patients whit SLE have an increased incidence of tuberculosis, and osteoarticular involvement occurs in 1%-3% of the cases, manifesting as pain, reduction in mobility, and increased osteoarticular volume. The radiographic findings are often nonspecific. Magnetic resonance imaging (MRI) is an useful test to define the severity of bone involvement; however, the etiological diagnosis can only be established by use of synovial fluid or bone cultures or the histological study of the affected areas. Due to the lack of specificity of the findings, there is usually a mean diagnosis delay of 11 months. We report the case of a female patient with SLE and predisposing factors for tuberculosis infection/reactivation. The MRI was important to define bone involvement, and the etiological diagnosis was established by use of bone biopsy. The patient also had lung involvement due to miliary tuberculosis, shown on plain chest radiography and CT scan and confirmed on culture of Mycobacterium tuberculosis in the sputum. There was a 1.5-month delay in beginning therapy, which is considered a short time when compared to the reports in the literature. In conclusion, bone tuberculosis, although rare, should always be remembered as a differential diagnosis of patients with SLE and osteomyelitis, mainly those with history of pulmonary tuberculosis.

Short duration respiratory illness with abducens palsy in a young man

Acute onset of diplopia associated with high-grade fever, sore throat and cough without features of raised intracranial tension in a young patient is an uncommon presentation. A diagnosis of abducent nerve palsy due to pontine tuberculoma associated with miliary tuberculosis was made based on sputum examination, chest x-ray and MRI. On diagnosis, monocular patching of the left eye was performed to avoid diplopia and primary antitubercular drugs with systemic steroids were given. An unfortunate 48 h delay in starting the antitubercular treatment likely decreased the probability of survival.

[A case of miliary tuberculosis showing diffuse alveolar hemorrhage]

A 43-year-old diabetic man had a productive cough and high fever and was admitted to another hospital. His condition did not improve despite treatment with Cefepime, and he was transferred to our hospital. Chest X-ray films and CT findings showed pulmonary infiltration and diffuse ground-glass opacities in bilateral lung fields, but disseminated nodules were not identified. Since his bronchial lavage fluid (BALF) was bloody, we suspected diffuse alveolar hemorrhage due to vasculitis. Steroid pulse therapy was given, and his fever and chest X-ray findings completely improved. However, 1 week later, he again suffered a high fever and bloody sputum, and a chest X-ray film showed granular shadows in bilateral lung fields. He died of respiratory failure on the 18th hospital day despite treatment and mechanical ventilation. An autopsy revealed many necrotizing epithelioid granulomas in both lungs, the liver, the spleen, both kidneys and both adrenal glands. These findings indicated miliary tuberculosis, and a culture of his sputum and BALF finally revealed mycobacterium tuberculosis. Marked alveolar hemorrhage and a hyaline membrane were also found in both lungs, but vasculitis was not recognized in any organ. We report this case, because to the best of our knowledge diffuse alveolar hemorrhage has not been reported as the primary symptom of miliary tuberculosis.

Bilateral spontaneous pneumothorax in miliary tuberculosis

Pneumothorax is a common complication in pulmonary tuberculosis that is usually seen with underlying cavitary lesion. However, it is uncommonly seen in patients with miliary tuberculosis. This communication describes bilateral spontaneous pneumothorax in an 18 years' old female patient having miliary tuberculosis.

[A case of tuberculous lateral great adductor muscle abscess during treatment of miliary tuberculosis]

We report a rare case of a thigh abscess which appeared during treatment of miliary tuberculosis. A 72-year-old woman with a history of diabetes mellitus was being treated for systemic sclerosis with prednisolone. She was then admitted to our hospital with fever, and chest computed tomography showed an abnormal shadow. She was given a diagnosis of miliary tuberculosis, and antituberculous therapy was initiated with isoniazid, rifampicin, ethambutol and pyrazinamide. Although this combination of antituberculous drugs was effective, 3 months after the initiation of treatment, a collection of fluid appeared in her left thigh. Further examination revealed the fluid to be positive for Mycobacterium tuberculosis on PCR and negative on mycobacterial culture. We thus diagnosed this phenomenon to be a paradoxical reaction.

[A case of miliary tuberculosis showing acute respiratory distress syndrome in rheumatoid arthritis]

A 62-year-old man, treated with corticosteroids and immunosuppressants for rheumatoid arthritis, visited hospital with high fever and dyspnea on exertion. A CT scan of the chest demonstrated bilateral diffuse ground glass opacities. On the basis of the findings of the CT scan, he was initially given a diagnosis of interstitial pneumonia. He was then referred to our hospital and admitted to the intensive care unit (ICU), where because of progressive respiratory failure, he was put on mechanical ventilation. A bronchoscopy specimen after intubation turned out to be positive for acid-fast bacilli, which were confirmed to be mycobacterium tuberculosis by a polymerase chain reaction test. He was given a diagnosis of miliary tuberculosis complicated with acute respiratory distress syndrome (ARDS). He died of respiratory failure despite treatment with antituberculosis drugs. The autopsy revealed necrotizing epithelioid granulomas in both lungs, mediastinal lymph nodes, the liver, both kidneys, vertebrae and other organs. Diffuse alveolar damage was also found in both lungs. It is often difficult to detect disseminated nodules in the miliary tuberculosis with ARDS. Miliary tuberculosis should be suspected in patients in an immunosuppressant state with rheumatoid arthritis, and who have respiratory symptoms or fever of unknown origin.

Tuberculosis pneumonia as a primary cause of respiratory failure--report of two cases

Tuberculosis (TB) is one of the treatable diseases rarely causing Acute Respiratory Failure (ARF). Hypoxic respiratory failure is often fatal in miliary tuberculosis and acute tuberculous bronchopneumonia. We describe two patients of tuberculous pneumonia with ARF who were successfully treated with early appropriate anti-tuberculosis therapy.

[A case of miliary tuberculosis difficult to distinguish from metastatic lung cancer]

We report a case of the coexistence of pulmonary tuberculosis and lung cancer maked a wrong diagnosis of lung cancer and metastatic lung carcinoma. The patient was a 80-years-old woman who had ascites and anorexia and decreased weight. Chest CT film showed a mass shadow in the right S, and infiltrative shadows on bilateral lung fields. FDG-PET revealed the tumor in the right lower lung field and many infiltrative shadows in all lung fields, and showed that FDG accumulated diffusely along the peritoneum. We made a diagnosis of lung cancer and metastatic lung carcinoma. However we obtained a diagnosis of coexisting of pulmonary tuberclosis and lung cancer autopsy. When the patient has a shadow suggestive of lung tumor shadow with many infiltrative shadows, we tend to make a diagnosis of lung cancer and metastatic lung carcinoma. We saw the importance of a postmortem examination in a new light.

[Hepatic tuberculosis presenting as prolonged fever]

In our country prolonged fever is frequently caused by tuberculosis infection, that is recrudescent. Localized hepatic tuberculosis is a rare clinical form of this specific infection. The authors present the case of a 26 year old man who developed prolonged fever, highly elevated liver enzymes and meningitis syndrome and was admitted to Clinical Hospital of Infectious Diseases and Pneumophtisiology Dr. V. Babeş Timişoara during 24.03 - 16.05.2008. Diagnosis of hepatobiliary tuberculosis, acute bacillary meningitis and miliary tuberculosis were established by clinical, laboratory criteria and sustained by imaging techniques. Dynamics of biological features, diagnostic pitfalls, differential diagnosis difficulties, therapeutic schedules and peculiar aspects of evolution are presented. Liver involvement can be the only manifest form of miliary tuberculosis and when it is associated with prolonged fever obligates to begin quadruple specific therapy, especially in communities where tuberculosis is prevalent. Bacteriological findings are belated and antituberculous therapy can not be started early. Quadruple association of antituberculous drugs with corticotherapy and liver protective medication showed utility in favorable resolving of this case.

[Multiple intestinal perforations due to tuberculosis: a case report and review of the literature]

The incidence of tuberculosis in Italy steadily decreased until two decades ago, but the infection is now frequently diagnosed in common clinical practice. The Authors describe a rare acute abdominal presentation of the disease featuring a double intestinal perforation in a subject affected by pulmonary, renal and gastrointestinal miliary tuberculosis. A review of the literature is also presented. Intestinal resection is the treatment of choice in such cases, even if it leads to frequent, major complications, but the authors stress that there may be a possibility for a less radical form of management of these patients.

Mucocutaneous histoplasmosis in HIV with an atypical ecthyma like presentation

Pulmonary and disseminated forms of histoplasmosis are very common in AIDS, but primary cutaneous histoplasmosis is rare. We report a case of primary mucocutaneous histoplasmosis in the setting of HIV.

[A case of miliary tuberculosis and esophageal perforation secondary to tuberculous mediastinal lymphadenitis]

An 80-year-old woman was admitted to a local hospital following transient disturbance of consciousness after a fall. High intermittent fever developed after hospitalization and she was diagnosed as having mediastinal abscess with esophageal perforation. She underwent mediastinal drainage and surgical repair of the esophagus. Acid-fast bacilli were detected in her sputum. Chest CT scanning showed a diffuse granular shadow. Then she was diagnosed as having miliary tuberculosis and treated with combination of INH, RFP, EB, and PZA. However, five days after treatment was initiated, fever and skin eruption appeared and treatment has to be stopped after one month. Then she was referred to our hospital. We gradually increased the dosages of INH and RFP, which resulted in pyrexia. Therefore, we changed EB to SM. Fever subsided and we were able to administer the full dose of drugs from the beginning of January 2007. Thereafter, the patient improved gradually. However, she died in February 2007. At autopsy, we identified tuberculous mediastinal lymphadenitis, inflammatory granuloma under the esophageal mucosa and miliary tuberculosis. We report this case as a rare case of miliary tuberculosis and esophageal perforation secondary to tuberculous mediastinal lymphadenitis.

A patient with hypercoagulable state due to tuberculosis

A 55-year-old male patient presented with status epilepticus following prolonged fever. Investigations revealed miliary opacities in lungs that were diagnosed as tubercular after thoracoscopic lung biopsy. Wide derangement of coagulation parameters was found, indicating a pro-coagulent state. There was evidence of widespread thrombosis.

Miliary tuberculosis associated with chronic neutrophilic leukemia

We report a case of miliary tuberculosis associated with chronic neutrophilic leukemia (CNL). A 70-year-old woman was referred to our hospital complaining of a 1-month history of persistent fever and anorexia. Chest and abdominal computed tomography images revealed diffuse small nodular lesions in the bilateral lung fields and extreme splenomegaly. Sputum cultures isolated Mycobacterium tuberculosis. After anti-tuberculous therapy for 1 year, the patient underwent splenectomy for massive splenomegaly and progressive leukocytosis. The presence of the homozygous JAK2 V617F tyrosine kinase mutation was also demonstrated in the peripheral blood. She was finally diagnosed as having miliary tuberculosis associated with CNL based on the histopathological examination of spleen. The patient was treated with a daily dose of 500 mg of hydroxyurea. As a result, 18 months after the splenectomy, her leukocyte count was decreased and her clinical condition was markedly improved; there was no relapse of the CNL.

Addison's disease induced by miliary tuberculosis and the administration of rifampicin

We herein report a rare occurrence of Addison's disease caused by acute adrenal gland tuberculosis occurring in association with miliary tuberculosis and the administration of rifampicin. An 82-year-old woman with miliary tuberculosis was treated with antituberculous chemotherapeutic agents including rifampicin (RFP), but she still demonstrated general malaise in addition to hyponatremia. Abdominal CT showed an enlargement of the right adrenal gland. However, after discontinuing RFP, the patient's symptoms improved. We carefully reinitiated the administration of RFP. The patient's condition thereafter did not worsen, and the treatment could thus be maintained. It is extremely important to immediately recognize adrenal crisis precipitated by the administration of RFP.

Hepatic granuloma in Turkish adults: a report of 13 cases

BACKGROUND

Hepatic granuloma (HG) is a well defined histopathological finding with an heterogenous clinical presentation. Diagnosis of a specific clinical entity is not possible every time. Descriptive studies may shed light on the various etiologies also common and distinctive findings among these patients.

METHODS

We reviewed the results of the liver biopsies of 592 patients. Characteristics of the patients with HG were extracted from the hospital charts. Laboratory studies included biochemical tests, hepatitis C virus (HCV) antibody, Brucella agglutination tests, tuberculin skin test. According to the diagnostic clues further tests (thoracic computed tomography (CT), ultrasonography, organ biopsy in addition to liver, antimitochondrial antibody, hepatitis B surface (HBs) antigen, venereal disease research laboratory (VDRL)) were performed.

RESULTS

HG was found in 13 of the 592 patients (2.2%). Primary biliary cirrhosis (three cases) was the most frequent cause followed by sarcoidosis, miliary tuberculosis and BCGitis (Bacillus Calmette Guerin) (two cases each). Two patients with HG could not be diagnosed. Only three patients had remarkable physical examination findings. Alkaline phosphatase and gamma-glutamyl transpeptidase were the most frequently elevated enzymes. Abdominal ultrasonography provided no specific diagnostic clue in any patient. Localization of the HGs was portal in 6 patients, parenchymal in 5 patients and both portal and parenchymal in 2 patients. Three exitus were due to BCGitis, miliary tuberculosis and fungal infection.

CONCLUSIONS

Tuberculosis is still among the most common etiologic factors. BCGitis has a fulminant rather than an indolent course. Abdominal ultrasonography could be used to rule out obstructive jaundice rather than to reach a specific diagnosis. Involvement of portal area by HG in most of the cases might cause obstruction of the biliary canaliculi and elevation of the cholestatic enzymes. Follow up of the difficult cases may be the best approach since the presence of HG was not proved as a bad prognostic factor for any disease.

Specific synovitis of a knee as the first manifestation of miliary tuberculosis

Tuberculosis (TB) is declared global emergency. Miliary TB is a treatable, potentially lethal form of TB resulting from massive lympho-hematogenous dissemination of Mycobacterium tuberculosis. Impaired cell-mediated immunity underlies the disease's development. We present a case of specific synovitis in a 21-year-old Caucasian HIV-seronegative woman. She presented with high fever and swelling of the right knee. Chest radiograph revealed bilateral nodular opacities in upper pulmonary lobes and signs of pleural effusions. Sputum samples were negative for Acid Fast Bacilli (AFB) and Löwenstein-Jensen (L-J) culture negative. Diagnosis was confirmed histologically by pleural biopsy and positive L-J cultures of knee puncture, also documented by MRI. Treatment outcome was successful with anti-tuberculous drugs following standardized treatment regimen.

[Cryptococcus neoformans meningitis in a HIV negative miliary tuberculosis-suspected patient]

Cryptococcosis caused by Cryptococcus neoformans has a wide range of clinical presentations, varying from asymptomatic colonization of the respiratory airways to the dissemination of infection into different parts of body. It is more common among immunosupressed patients such as human immunodeficiency virus (HIV) positive ones. In this report we present a case with C. neoformans meningitis and miliary pulmonary infiltrates suggesting pulmonary tuberculosis without HIV infection. A-70-years-old male was admitted to the hospital with mental confusion, 3-weeks history of headache, weight loss, dry cough and fatigue. Physical examination was normal except neck stiffness. Cerebrospinal fluid (CSF) white cell count was 120/mm3 (80% polimorphonuclear cells). Gram staining of CSF revealed poorly stained gram-positive yeast cells. Empirical therapy with lipozomal amphotericin B, ceftriaxone and ampicillin combination was started. When C. neoformans growth was detected on CSF culture, ceftriaxone and ampicillin were discontinued. Patient became conscious at 24th hour of the treatment. Peripheric blood flow-cytometric analysis revealed a significant decrease in absolute CD4+ T lymphocytes, and in CD8+28+ T lymphocytes in addition a significant increase in natural killer cell ratio. Blood immunoglobulin and complement levels were found normal. Cranial magnetic resonance imaging and computerized tomogralphy (CT) of the abdomen were normal, however, chest CT revealed multiple parenchymal millimetric nodular infiltrations on both sides and minimal fibrotic alterations. Acid-fast staining of CSF, tuberculosis culture, tuberculosis PCR results and repeated HIV serology were found negative. Despite the lack of microbiological confirmation, empirical antituberculosis treatment was also started with the suspicion of miliary tuberculosis as the patient had a symptom of long-term dry cough, miliary infiltrations on chest CT, anergic tuberculin skin test and a history of pulmonary tuberculosis in childhood. After two weeks, amphotericin B was changed to oral fluconazole which was continued for an additional eight weeks. Antituberculosis therapy was given for nine months. Control chest CT taken after four months of antituberculosis therapy revealed improvement of the lesions. This presentation emphasizes the fact that cryptococcal infections may develop in HIV negative patients, even together with tuberculosis in certain cases and radiological findings of the two infections may be confusing when both of them invade the lungs.

[Cosyntropin test in severe active tuberculosis]

BACKGROUND

Frequency of adrenal insufficiency in patients with tuberculosis varies from 0 to 58%; however, all published series excluded severely ill patients. Our objective was to investigate adrenal insufficiency with the low-dose cosyntropin test in patients with severe active tuberculosis.

METHOD

From two large university affiliated hospitals, 18 patients with tuberculosis and criteria of sepsis or severe sepsis according to SCCM/ACCP criteria, defined by the present authors as severe active tuberculosis, participated in the study. A low-dose ACTH test with 10 mg of ACTH was performed. After ACTH test, all patients received a stress dose of hydrocortisone (240 mg/day) during their entire hospitalization along with four antituberculous drugs. Abnormal response was considered when elevation of serum cortisol was <7 microg/dl with respect to basal level, 60 min after ACTH administration.

RESULTS

Adrenal insufficiency was found in seven patients (39%); no clinical or laboratory data were associated with the presence of abnormal adrenal response. Except in one patient with HIV infection, all the signs and symptoms improved after antituberculous and hydrocortisone treatment. The increment in serum cortisol value post-ACTH test was lower in patients with hypoalbuminemia.

CONCLUSIONS

Adrenal insufficiency is frequent in severe active tuberculosis. The efficacy and security of supplemental steroid treatment in severe active tuberculosis should be established by a randomized clinical trial.

[Middle cerebral artery ischemic stroke presentation of miliar tuberculosis]

Presence of central nervous system by extrapulmonary tuberculosis is an infrequent disease specially among non HIV infected patients, and it is associated with poor prognosis and high mortality rates. We report a case with a middle cerebral artery ischemic strocke as a first symptom of miliar tuberculosis.

[Difficulty in diagnosing pediatric tuberculosis]

Tuberculosis (TB) in children is an important warning sign in a community, as it could signal recent infection of a cavitary form in an adult. Thus, while early diagnosis is crucial for effective treatment in children, it is also imperative for the control of tuberculosis at the public health level since it allows rapid identification of contagious adult cases. Here we report four cases of difficult and delayed diagnosis of TB in children. From this experience we highlight the need for an extensive medical history of the patient during diagnostic work-up. This includes: the positive history for contact with infected adults, especially for immigrant children; exclusion of TB diagnosis for persistent respiratory symptoms (2-3 weeks) after antibiotic therapy; and the need for high-definition CT scan when the radiological picture is not specific, especially for children under 5 years of age.

[A case of miliary tuberculosis showing acute respiratory failure during pregnancy]

A 36-year-old Philippine woman had had fever and general fatigue from September, 2006 (11th week of pregnancy). She was admitted with high fever, general fatigue and dyspnea on October 16, 2006 (13th week of pregnancy). A chest radiograph on admission showed bilateral miliary shadows and ground glass shadows. She already had severe hypoxia on admission. As acid-fast bacilli were positive in urine (Gaffky 8) and sputum (Gaffky 1), we diagnosed as miliary tuberculosis and pulmonary tuberculosis complicated with acute respiratory distress syndrome (ARDS). We treated her with antituberculosis chemotherapy, corticosteroid, sivelestat sodium hydrate, direct hemoperfusion using a polymyxin B immobilized column, and mechanical ventilation, but she died due to respiratory failure. We emphasize that in this case pregnancy has the risk of to causing disease progression of miliary tuberculosis and we should treat immediately and intensively for miliary tuberculosis complicated with ARDS.

Chest computerized tomography scan findings in 74 children with tuberculous meningitis in southeastern Turkey

This prospective study was done over seven years from 1996 to 2003 to investigate the chest computed tomography scan findings along with other radiologic examinations that included chest roentgenography and cranial computed tomography in children with tuberculous meningitis (TBM). Chest roentgenography demonstrated abnormal findings in 32 cases (43%) (hilar adenopathy, 32%; miliary pattern, 18%; bronchopneumonic infiltrate, 24%), while chest computerized tomography was abnormal in 65 cases (88%; p<0.005): mediastinal and hilar lymphadenopathy were present in 46% (p<0.005); miliary pattern, in 23% (p<0.05); and bronchopneumonic infiltrate, in 23% (p<0.05). Cranial computerized tomography was abnormal in 68 cases (92%). Chest computerized tomography scan helps establish the diagnosis of TBM when chest radiography is normal or inconclusive, and it is useful in assessing children with suspected TBM.

Pseudocalcification on chest CT scan

Liquid ventilation with perfluorocarbons is used in severe respiratory failure that cannot be managed by conventional methods. Very little is known about the use of liquid ventilation in paediatric patients with respiratory failure and there are no reports describing the distribution and excretion of perfluorocarbons in paediatric patients with severe respiratory failure. The aim of this report is to highlight the prolonged retention of perfluorocarbons in a paediatric patient, mimicking pulmonary calcification and misleading the interpretation of the chest CT scan. A 10-year-old girl was admitted to our intensive care unit with severe respiratory failure due to miliary tuberculosis. Extracorporeal membrane oxygenation (ECMO) was used to support gas exchange and partial liquid ventilation (PLV) with perfluorodecalin was used to aid in oxygenation, lavage the lungs and clear thick secretions. The patient developed a pneumothorax (fluorothorax) on the next day and PLV was discontinued. Multiple bronchoalveolar lavages were performed to clear thick secretions. With no improvement in lung function over the next month a CT scan of the chest was performed. This revealed extensive pulmonary fibrosis and multiple high attenuation lesions suggestive of pulmonary calcification. To exclude perfluorodecalin as the cause for high attenuation lesions, a sample of perfluorodecalin was scanned to estimate the Hounsfield unit density, which was similar to the density of high attenuation lesions on chest CT scan. High-density opacification should be interpreted with caution, especially following liquid ventilation.

Topical Steroids in the Management of Churg-Strauss Syndrome Involving the Conjunctiva

PURPOSE

To discuss a case of Churg-Strauss syndrome that developed bilateral conjunctival involvement while recovering from miliary tuberculosis.

METHODS

Case report and literature review.

RESULTS

A 22-year-old man who was on oral prednisolone for Churg-Strauss syndrome since 2002 contracted miliary tuberculosis in June 2004. The diagnosis was confirmed by liver biopsy. Ophthalmologic examination was within reference limits except for bilateral multifocal choroiditis. A combined therapy of rifampicin, ethambutol, streptomycin, and morphazinamide was started on June 24, 2004. Complete recovery was achieved, and the antituberculosis therapy was terminated in June 2005. The patient noted redness and pain in both eyes a month later. He had bilateral irregular, pink-yellow, gravel-like infiltrations involving the bulbar conjunctiva. Biopsy revealed granulomas with central fibrinoid necrosis, histiocytes, and eosinophils, suggestive of conjunctival involvement of Churg-Strauss syndrome. Topical dexamethasone 0.1% drops were started 4 times per day and tapered gradually. Lesions totally regressed within 2 months. No recurrence was noted during a follow-up of 11 months.

CONCLUSIONS

Churg-Strauss syndrome may rarely involve the conjunctiva, and conjunctival lesions respond favorably to topical steroids.

Simultaneous occurrence of multiple types of cutaneous tuberculosis (TVC and PNT) with internal organ tuberculosis (PTB)

A 40 years old male patient of poor socioeconomic condition presented with a well circumscribed rough surfaced and fissured, verrucous plaque on left axilla and a similar lesion on right foot- which were clinically diagnosed as tuberculosis verrucosa cutis. He also had necrotic papular eruption with varioliform scarring in some lesions on upper back clinically diagnosed as papulonecrotic tuberculid. He had fever and cough and mild weight loss suspicious of pulmonary tuberculosis. On investigation ESR was raised, mild anaemia was present, MT was strongly positive, chest x-ray was suggestive of tuberculosis. So, he was diagnosed as a case of simultaneous occurrence of tuberculosis verrucosa cutis (TVC) with papulonecrotic tuberculid (PNT) with pulmonary tuberculosis (PTB). Standard anti tuberculosis chemotherapy already started to offer cure of all lesions.

TB-related sudden death (TBRSD) due to myocarditis complicating miliary TB: a case report and review of the literature

TB-related sudden death (TBRSD) is rarely reported in the literature and in the majority of cases is due to bronchopneumonia and hemoptysis. Cardiac complications of tuberculosis causing sudden death can take many forms and are rarer still, with only a handful of cases reported. We describe a case of a previously fit and healthy 20-year-old Asian female who, after returning from a holiday in India, collapsed while getting off a bus. At postmortem, the only macroscopic finding of note was a localized area of fibrosis on the anterior wall of the left ventricle. Microscopic examination of this area showed Langhans giant cells; noncaseating epithelioid granulomas and acid-fast bacilli were demonstrated on Ziehl Nielsen staining. In addition, the lungs, liver, and kidneys contained multiple noncaseating granulomas. The case serves to highlight the protean nature in the presentation of this disease and the importance of postmortem histology in autopsy work.

[Diagnostic image (309). An Indonesian woman with headache, confusion and fever]

A 30-year-old Indonesian woman presented with headache, confusion, vomiting, diplopia and fever, due to multiple intracranial tuberculomata.

[A case of tuberculous aneurysm of subclavian artery occurred in the course of treatment for miliary tuberculosis]

This case is a 56-year old woman. Steroids were being administered perorally after a thymectomy for myasthenia gravis. A fever of 38-39 degrees Celsius appeared during night, an abnormal shadow showed up on a chest X-ray and the patient was hospitalized. Gaffky No. 2 acid-fast bacilli were detected in the patient's sputum and the chest CT showed diffuse granular-like shadow, the patient was diagnosed as miliary tuberculosis and treatment with combined use of INH, RFP, EB, and PZA was started. Subsequently, fever started to subside and the miliary shadow on chest X-ray improved, however, six weeks after the start of treatment, hoarseness and dysphagia appeared. From the cervical CT and cervical angiography findings, the diagnosis of right subclavian artery impending ruptured aneurysm was made. Because the patient's sputum was acid-fast bacilli positive and because the patient had undergone thymectomy, it was decided that it would be difficult to treat her by a thoracotomy again. Therefore, a right subclavian artery stent insertion, right subclavian artery-right common carotid artery bypass creation operation was carried out with the objective of blocking the flow of blood to the aneurysm. The hoarseness and dysphagia improved post-operatively and the patient's progress is being monitored. Tuberculous aneurysms are a rare affection and they are mostly discovered when the autopsy is done, however, this case was diagnosed due to the manifestation of subjective symptoms. While this case was not diagnosed histopathologically, it is envisaged from the clinical progress that this was a tuberculous subclavian aneurysm complicated during the treatment for miliary tuberculosis.

Thrombose veineuse cérébrale aseptique et tuberculomes cérébraux compliquant une miliaire tuberculeuse pulmonaire

INTRODUCTION

Severe pulmonary tuberculosis may be complicated by deep vein thrombosis due to a state of hypercoagulability.

OBSERVATION

We report a case of pulmonary miliary tuberculosis associated with cerebral venous thrombosis and multiple intracranial tuberculomas. A 65-year-old woman developed a confusional syndrome one week after starting treatment for pulmonary military tuberculosis. Neuroimaging reveals a thrombus in the right lateral sinus and multiple silent intracranial tuberculoma.

CONCLUSION

The patient was given anticoagulants and fully recovered.

Laparoscopy in the evaluation of women with unexplained ascites: An invaluable diagnostic tool

STUDY OBJECTIVE

To assess whether laparoscopy is a reliable technique for the investigation of women presenting with ascites and in whom the diagnosis remains obscure.

DESIGN

Prospective nonrandomized clinical study (Canadian Task Force classification II-2).

SETTING

University Departments of a tertiary referral center.

PATIENTS

Women presenting in our institution with ascites in whom the diagnosis remained obscure after an extensive nonoperative diagnostic work-up.

INTERVENTION

Undiagnosed cases were submitted to laparoscopy, and selective biopsy specimens were taken for histologic study.

MEASUREMENTS AND MAIN RESULTS

Over a 3-year period, 73 patients were admitted to our institution with diffuse ascites. In 9 patients (12.3%), the diagnosis remained obscure, and these patients were further investigated with laparoscopy. Selective biopsy specimens obtained at laparoscopy clarified the specific cause of the ascites in all 9 patients. Peritoneal carcinomatosis was responsible in 5 patients (a metastatic gastrointestinal tumor in 1 patient, a malignant mesothelioma of the peritoneum in 1 patient, and a serous papillary carcinoma of the peritoneum and of the ovary in 2 and 1 patients, respectively). Three patients were found with miliary peritoneal tuberculosis, and the last patient had an unusual peritoneal reaction to methylene blue after laparoscopic adhesiolysis.

CONCLUSION

Laparoscopy is a valuable means of assessing the peritoneal cavity in patients with unexplained ascites, where the primary cause remains unclear. The diagnosis can be accurately made with selective biopsy specimens, and appropriate treatment can be instituted without delay.

[Lymphoid form of intestinal tuberculosis with miliary dissemination: case report]

Tuberculosis with the incidence 28-29/100000 residents still presents a major public health problem in Croatia. Miliary tuberculosis is uncommon cause of fever of unknown origin. Intestinal tuberculosis pose as diagnostic problem that can be identified by colonoscopy and/or explorative laparatomy involving histopathology and microbiology. A case is reported of a 40-year-old HIV negative patient admitted to the Department of Infectious Diseases after two weeks of fever, diarrhea, abdominal pain and weight loss. Biochemistry testing showed mild elevation of the erythrocyte sedimentation rate and increased serum aminotransferases. On admission, chest x-ray was normal and tuberculin skin test was negative. Crohn's disease was suspected. Computed tomography of the abdomen revealed solid infiltrative mass located retroperitoneally, along with enlarged lymph nodes. Explorative laparoscopy was necessary to confirm the diagnosis. Intraoperative specimens were referred for histopathologic and microbiologic examination, which proved the existence of granulomatous inflammation of the areas with caseous necrosis. Direct microscopy of the periappendicular abscess and Ziehl-Neelsen staining of a lymph node specimen confirmed the presence of an acidoresistant bacillus. The specimen culture on solid egg based agar (Löwenstein Jensen) and liquid broth (MGIT) showed the growth of Mycobacterium tuberculosis. Then the causative agent was cultured from all specimens: sputum, stool and urine. Repeat cheast x-ray, performed on day 30 of hospitalization, showed miliary dissemination to the lungs. The patient was treated with four antituberculotics (streptomycin, isoniazide, rifampin, ethambutol) and methylprednisolone for one month, then with isoniazide, rifampin and for 11 months ethambutol. Therapy led to a decrease of abdominal lymph nodes and absence of miliary lesions on chest radiography after two months of treatment. Intestinal tuberculosis has been almost forgotten in Croatia. The latest published cases referred to HIV infected patients. In less than 50% of patients with intestinal tuberculosis the lungs are also affected, which poses a diagnostic problem. Crohn's disease is the most common diagnostic problem. Histopathology of a specimen obtained on colonoscopy and/or explorative laparoscopy can often solve the dilemma, as also confirmed in our patient. Of diagnostic studies, computed tomography has the advantage of evaluating intestinal wall involvement, which is important for the early diagnosis of intestinal tuberculosis. Enteroclysis and irrigography provide diagnostic information in the advanced stage of intestinal tuberculosis. In a patient with fever, abdominal disorders and parameters which implicate granulomatosis hepatitis or Crohn's disease, the existence of abdominal tuberculosis is also possible. Computed tomography and biopsy obtained on colonoscopy for microbiology can help in making the diagnosis and initiating appropriate treatment.

[A case of miliary tuberculosis complicating acute Q fever]

A 73-year-old man was admitted with fever and abnormal liver function test. After admission, his fever persisted in spite of administrating a variety of antibiotics. He was diagnosed as acute Q fever on the basis of a high titer of IgM antibodies against phase II Coxiella burneti. His fever resolved after starting minocycline, but biliary enzymes continued to be elevated. Transbronchial lung biopsy and percutaneous liver biopsy revealed caseating granulomas and Mycobacterium tuberculosis was detected by culture. Miliary tuberculosis was diagnosed and his biliary enzymes declined after starting therapy with antituberculous drugs. This report of miliary tuberculosis complicating acute Q fever is a valuable and unprecedented case.

A case of miliary tuberculosis presenting with bowel perforation

Tuberculosis is a disease that should never be underestimated. It can affect anybody at any age. Doctors in the West do not have much experience of peritonitis secondary to tuberculosis. It is a condition that requires urgent and aggressive management as it can be fatal, even in the young and fit, as this case report illustrates.

[Case of disseminated tuberculosis complicated with tuberculous meningitis while investigating an abdominal lymphadenopathy]

In February 2005, a 33-year-old man visited A hospital complaining of fever. The blood screening test revealed the liver dysfunction, then computed tomography showed swelling of abdominal lymph nodes. In April, headache and disorientation appeared. He was diagnosed as disseminated tuberculosis and tuberculous meningitis based on chest X-ray and computed tomography findings and examination of cerebrospinal fluid. After admission to our hospital, anti-tuberculous drugs were prescribed, but the cerebral infarction happened. The disturbance of consciousness and the left half of his body paralysis appeared. They did not improve and hydrocephalus was complicated in August, though he was treated by steroids. He needed all helps because of the left half of his body paralysis and an advanced sequelae was left. It was thought that the abdominal lymph adenopathy preceded as one of symptoms of the disseminated tuberculosis in this case. It is said to be rare that abdominal lymph node swelling is seen in the early stage of disseminated tuberculosis. But, we think that it is necessary to keep in mind that the possibility of disseminated tuberculosis as one of the diseases in differential diagnosis, when we examine enlargement of abdominal lymph nodes with symptoms suggesting the presence of infection such as fever.

Intestinal perforation due to miliary tuberculosis in a patient with Behcet's disease

Gastrointestinal manifestations of both Behçet's disease and intestinal tuberculosis include the signs and symptoms of abdominal pain, weight loss, fever, vomiting, diarrhea and palpable mass in the right lower quadrant. We report the case of a male patient with Behçet's disease who had multiple ileal perforations due to miliary tuberculosis. It was suspected that the perforations were due to intestinal manifestation of Behçet's disease, but the final pathology report and chest X-ray one week after surgery demonstrated the presence of miliary tuberculosis. To our knowledge, this is the first reported case of Behçet's disease with intestinal perforation due to miliary tuberculosis.

Miliary tuberculomas of the brain: case report

Tuberculosis (TB) of the central nervous system (CNS) is still prevalent in many developing countries. Tuberculoma is always considered in the differential diagnosis of enhancing intra-axial lesions of the brain. Brain tuberculomas can present in many different clinical and radiological patterns, disseminated or miliary brain tuberculomas are very rare. We describe the case of a 25-year-old immunocompetent female with miliary brain tuberculomas. She presented with a history of progressive headache and unsteady gait. Serial Magnetic resonance imaging (MRI) studies revealed growing, multiple small enhancing lesions in the brain, most lesions measured approximately 2mm in diameter, in both the supratentorial and infratentorial compartments. Her investigation failed to reveal any evidence of TB outside the CNS. Open biopsy revealed multiple caseating granulomas and mycobacterin tuberculosis was cultured. She improved clinically and radiologically after starting anti-tuberculous pharmacotherapy. The clinical course, radiological images and pathological studies of this patient are presented. In conclusion miliary brain tuberculomas are rare and unique clinical and radiological entity. It may affect immunocompetent individuals with no other signs of other systemic involvement.

[Can optic perineuritis be triggered by Mycobacterium tuberculosis?]

A 38-year-old woman presented with a swollen left optic disc while being treated for miliary tuberculosis. The diagnosis of optic perineuritis was made, antibiotics were adapted, and the patient slowly recovered. We discuss the elements required to confirm optic perineuritis and the differential diagnosis in cases of papilledema with no visual impairment, as well as the hypotheses on the possible etiologies: dysimmune neuropathy as opposed to infection or toxicity.
