Tuberculosis is a common chronic infectious disease, although the spleen is an uncommon organ to harbor tubercle bacilli. Immunocompromised subjects are primarily prone to miliary tuberculosis and in them the spleen is invaded by Mycobacterium tuberculosis. Spleen tuberculosis is manifested commonly as a miliary form. The basic pathology is granulomatous inflammation. The CT finding of splenic tuberculosis are multiple, well-defined, roung or ovoid, low-density masses. Lymphadenopathy in the abdomen and mediastinum and pleural effusion can be found. We report two cases with tuberculosis of the spleen proved by computed tomography and histologic identification. One paitient did not improve following antituberculous medication, so splenectomy was performed. The other patient has been treated with antituberculous medication.

Since the diagnosis of extrapulmonary tuberculosis (EPT) is largely depended on the physician's suspicion in respect of the disease, we believed that it would be worthwhile to scrutinize the clinical characteristics of EPT. Thus, here we present retrospectively evaluated clinical manifestations of patients who were diagnosed as EPT cases in a tertiary referral care hospital. Medical records of 312 patients, diagnosed as having EPT at Yongdong Severance hospital from January 1997 to December 1999, were reviewed retrospectively. In total 312 patients, 149 (47.8%) males and 163 (52.2%) females aged from 13 years to 87 years, were included into this study. The most common site of the involvement was pleura (35.6%). The patients complained of localized symptoms (72.4%) more frequently than systemic symptoms (52.2%). The most common symptom was pain at the infected site (48.1%). Leukocytosis, anemia, and elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were found in 12.8%, 50.3%, 79.3% and 63.1% of the patients, respectively. Twenty-four percent of the patients had underlying medical illnesses such as, diabetes mellitus or liver cirrhosis, or were over 60 years old. In 67.3% of patients, tuberculosis was suspected at the initial visit. However, tuberculosis was microbiologically proven in only 23.7% of the patients. The time interval from the symptom onset to the diagnosis varied, with the mean duration of the period 96 days. Pulmonary parenchymal abnormal lesions were found in 133 patients (42.6%) on chest radiographs. EPT has a wide spectrum of clinical manifestations, so it is difficult to diagnose it. Based on our studies, only 11.2% of the patients were confirmed as EPT. So it is important that the physician who first examines the patient should have a high degree of suspicion based on the chest radiography, localized or systemic symptoms and several laboratory parameters reviewed in this study.

A total 12 cases of tuberculous spondylitis of thoracic spine had been treated by anterior decompression and interbody fusion through extrapleural approach from March, 1979 to June, 1980. In this study, six impending or complete paraplegics were included. Prognosis of paraplegia depends on its grade, duration and local pathology. Extrapleural approach seems to offer the following advantages over all the other ones; lesser risk, no Iimitation of surgical fleid, less chance of contaminating pleural cavity, less postoperative complications, especially indicated for the elderly paraplegics of Incomplete or complete type and less cumbersome Immediate postoperative care.

Tuberculous pleural effusion (TPE) leads to residual pleural opacity (RPO) in a significant proportion of cases. The aim of this study was to investigate which TPE patients would have RPO following the treatment. This study was performed prospectively for a total of 60 TPE patients, who underwent pleural fluid analysis on the initial visit and chest radiographs and computed tomography (CT) scans before and after the administration of antituberculous medication. At the end of antituberculous medication, the incidence of RPO was 68.3% (41/60) on CT with a range of 2-50 mm. Compared with the non-RPO group, the RPO group had a longer symptom duration and lower pleural fluid glucose level. On initial CT, loculation, extrapleural fat proliferation, increased attenuation of extrapleural fat, and pleura-adjacent atelectasis were more frequent, and parietal pleura was thicker in the RPO group compared with the non-RPO group. By multivariate analysis, extrapleural fat proliferation, loculated effusion, and symptom duration were found to be predictors of RPO in TPE. In conclusion, RPO in TPE may be predicted by the clinico-radiologic parameters related to the chronicity of the effusion, such as symptom duration and extrapleural fat proliferation and loculated effusion on CT.

Tuberculous pericarditis is a rare form of tuberculosis usually presenting as pericardial effusion or constrictive pericarditis. But rarely it may present as pericardial mass. We experienced a case of tuberculous pericarditis presenting as pericardial mass which was confirmed by open thoracotomy. The patient was 34-year-old female, who was previously treated for tuberculous pleurisy. She admitted for dyspnea on exertion and imaging study including chest CT and echocardiography showed pericardial mass. Open thoracotomy showed hard adhesive mass lesion around pulmonary artery and pathology showed chronic granulomatous inflammation with caseation necrosis. We report a rare case of tuberculous pericarditis presenting as pericardial mass.

PURPOSE: Tuberculous pleurisy is the most frequent extrapulmonary manifestation of tuberculosis. In spite of adequate treatment, pleural fibrosis is a common complication, but the mechanism has not been elucidated. This study is to determine whether epithelial to mesenchymal transition (EMT) of mesothelial cells occurs in tuberculous pleurisy. MATERIALS AND METHODS: Normal pleural mesothelial cells, isolated from irrigation fluids during operations for primary spontaneous pneumothorax, were characterized by immunofluorescence and reverse transcription polymerase chain reaction (RT-PCR). These cells were treated in vitro with various cytokines, which were produced in the effluents of tuberculous pleurisy. The isolated cells from the effluents of tuberculous pleurisy were analyzed by immunofluorescence and RT-PCR analysis. RESULTS: The isolated cells from the irrigation fluid of primary spontaneous pneumothorax had epithelial characteristics. These cells, with transforming growth factor-beta1 and/or interleukin-1beta treatment, underwent phenotypic transition from epithelial to mesenchymal cells, with the loss of epithelial morphology and reduction in cytokeratin and E-cadherin expression. Effluent analysis from tuberculous pleurisy using immunofluorescence and RT-PCR demonstrated two phenotypes that showed mesenchymal characteristics and both epithelial & mesencymal characteristics. CONCLUSION: Our results suggest that pleural mesothelial cells in tuberculous pleurisy have been implicated in pleural fibrosis through EMT.

OBJECTIVETo explore the value of pleural biopsy in the diagnosis of tuberculous pleurisy in children.

METHODFifty-one cases with tuberculous pleurisy, whose diagnosis was established according to the clinical diagnostic criteria of the child pulmonary tuberculosis formulated by the Chinese Medical Association (CMA) in 2006, after pleural biopsy hospitalized in Children's Hospital of Chongqing Medical University from Jan. 1, 2007 to Jan. 1, 2013 were enrolled into this study. Clinical symptoms, history traits, laboratory examination, imaging tests, pleural fluid characteristics and the results of pleural biopsy were retrospectively analyzed. Medical records of the cases who were diagnosed with tuberculous pleurisy by histological examination were reviewed to assess tuberculosis detection rate of pleural biopsy and to get the percentage of cases with a preoperative diagnosis inconsistent with the final diagnosis.

RESULTThere were 35 boys and 16 girls, and the mean age was (9.7 ± 3.5) years. The common symptoms included fever (82%), cough (71%) , chest pain (23%), weakness (10%) and shortness of breath (10%); 27% (14/51) children had shown tuberculosis toxic symptoms; 76% (39/51) patients had BCG vaccination history; 12% (6/51) cases had a history of contact with tuberculosis patients. The positive rates of the tuberculin skin test, serum tuberculosis antibody detection, detection of Mycobacterium tuberculosis DNA by polymerase chain reaction, acid-fast bacillus test of sputum (or gastric juice) smear, acid-fast bacilli (AFB) smear and culture of pleural effusion were respectively 61% (20/33), 6% (3/46), 0 (0/12), 4% (1/27), 22% (7/32). Pleural effusion was found by using imaging tests in 50 cases, among whom 28 cases (55%) with encapsulated effusion, and the multilocular cysts separated by fibrous tissue in 12 patients (23%) . Other features included pleural thickening (53%) , hilar and mediastinal lymph-nodes enlargement (14%) and white nodules of calcification (10%) . Thoracocentesis was performed in 31 cases, and pleural effusion obtained from which were exudative. The cell count, mainly mononuclear cells, increased in 28 patients (90%) . Among the 51 children investigated, 47 (92%) were histologically diagnosed to be tuberculous pleurisy. The typical pathologic changes of tuberculosis (caseous necrosis, granulomas, Langhans' giant cells and inflammatory cell infiltration) were observed in 40 cases, granulomatous inflammation without caseous necrosis were the main manifestations in 7 other patients. The pathological changes of the remaining 4 cases were not consistent with the pathological characteristics of tuberculosis. All 47 cases were given a preoperative diagnosis of tuberculous pleurisy (32%), purulent pleurisy (51%) and pleural effusion of unknown origin (17%) respectively before pleural biopsy. Therefore, the tuberculosis detection rate of pleural biopsy was 92%, and the preoperative misdiagnosis rate was 68%.

CONCLUSIONPleural biopsy was of great diagnostic value for children with tuberculous pleurisy.
