BACKGROUND AND OBJECTIVES: The identification of a specific etiology of effusive pericardial disease is difficult because of the limited yield of cytologic and microbiologic pericardial fluid analysis. We performed retrospective study to find out whether pericardial biopsy was superior to pericardial fluid analysis in search of the etiology of pericardial effusion. MATERIALS AND METHOD: We reviewed 76 cases of moderate to severe pericardial effusion on which we performed surgical pericardial biopsy from Sep. 1986 to Sep. 1996. The results of pericardial fluid analysis, clinical manifestation, pericardial biopsy were compared retrospectively. RESULTS: 1)Clinical diagnosis of pericardial effusion were as follow:neoplastic disease (7.9%), tuberculosis (72.4%), constrictive pericarditis (17.1%), and others (2.6%). 2)By the percutaneous pericardial biopsy, we confirmed 19 cases (25%). Etiology of 4 cases (5.3%) were malignancy and 15 cases (19.7%) tuberculosis. Fifteen out of 76 patients who were diagnosed by biopsy as tuberculous pericarditis and 28 patients who were suspected as tuberculous pericarditis clinically were treated with antituberculous medications. Ten patients (66.7%) of pathologically diagnosed patients and 18 patients (69.2%) of clinically diagnosed patients showed complete resolution of pericarditis. CONCLUSION: By pericardial biopsy, we only confirmed 19 cases (25.0%). It means that pericardial biopsy is not superior to pericardial fluid analysis in searching of etiology of pericardial effusion. Moreover, it is not sufficient for final diagnosis of pericardial effusion.

We report aprimary malignant pericardial mesothelioma. Thirty-eight-year-old male patient complained of dyspnea and chest pain with left shoulder pain. At first, we thought it was because of tuberculous constrictive pericarditis and performed medical management for one and a half years. But, the above symptom recurred repeatedly; therefore we did pericardiectomy and diagnosed his case as malignant pericardial mesothelioma. Tumor was sticked to the myocardium and complete resection was impossible. He received postoperative chemoradiotherapy.

BACKGROUND AND OBJECTIVES: Tuberculous (TB) pericarditis is a major cause of constrictive pericarditis requiring pericardiectomy. We sought to determine initial prognostic factors in patients with TB pericarditis. SUBJECTS AND METHODS: We evaluated initial presentation and clinical outcomes (mean follow-up 32+/-27 months) in 60 consecutive patients newly diagnosed with TB pericarditis. RESULTS: Initial presentations were pericardial effusion (PE), effusive-constrictive pericarditis, and constrictive pericarditis in 45 (75%), 9 (15%), and 6 (10%) patients, respectively. Of the 54 patients without initial constrictive pericarditis, 32 (59%) showed echogenic materials in PE, including frond-like exudative coating and fibrinous strands. These patients had a longer disease duration before diagnosis, were initially more symptomatic, in a more advanced state, showed more persistent pericardial constrictions (38% vs. 0%, p<0.001) despite anti-TB medications, and tended to require pericardiectomy more often (19% vs. 0%, p=0.07, p<0.05 by Kaplan-Meier). All patients with effusive-constrictive pericarditis showed echogenic PE. Of the 60 total patients, 10 (17%) underwent pericardiectomies during follow-up. All of these patients showed initial pericardial constrictions, whereas no patient without initial pericardial constriction underwent pericardiectomy (p<0.001). Seven patients showed transient pericardial constrictions that resolved without pericardiectomy. CONCLUSION: Initial pericardial constriction and echogenic PE are poor prognostic signs for persistent pericardial constriction and pericardiectomy in patients with newly diagnosed TB pericarditis. These results suggest that early diagnosis and prompt anti-TB medication may be critical.

There is no diagnostic study for the presence of tuberculous pericarditis that is highly accurate as well as safe and easy to perform. As a result, the diagnosis is often delayed or missed, resulting in a clinical course characterized by increased mortality and late complications. Adenosine deaminase (ADA) in pleural or pericardial fluid is known for a useful marker of extrapulmonary tuberculosis. A 76-year old woman visited for dyspnea and generalized edema. Culture for sputum, pleural fluid, and pericardial fluid were negative for tubercle bacillus. But We diagnosed tuberculous pericarditis with pleuritis by increased titer of ADA activity in the pericardial fluid. After 2 weeks of initiation of antituberculous treatment, pericardial and pleural effusion gradually decreased while clinical symptoms improved markedly. Therefore, authors report a case of tuberculous pericarditis diagnosed by increased ADA activity in pericardial fluid with reviewing the previous literatures.

Primary pericardial mesothelioma is an extremely rare neoplasm with a bleak prognosis. It is often misdiagnosed as constrictive pericarditis initially, especially as tuberculosis pericarditis in Korea due to the high incidence of active tuberculosis. A targeted pericardial biopsy and noninvasive imaging modalities, such as delayed phase contrast chest computed tomography (CT) images and magnetic resonance imaging (MRI), can play an important role in the differential diagnosis of pericardial disease. We present the case of a 37-year-old man with a 3-week history of exertional dyspnea. A large pericardial effusion with pericardial thickening was noted, but its etiology was not revealed after conventional diagnostic procedures, including a closed pericardial biopsy. Empirical antituberculosis treatment was started, but the dyspnea recurred 5 months later. A malignant pericardial mesothelioma was diagnosed through a pericardiectomy and biopsy under direct visualization

Adenosine deaminase(ADA) is an enzyme capable of catalysing the pathway from adenosine to inosine. Previous studies have shown that this enzyme may be useful in recognition of a tubeculous etiology of pleural, peritoneal, or meningeal effusions. ADA activity was studied in 42 patients with large amount of pericardial effusion. Patients were subdivided into the following four group : (A) 15 cases of tuberculous effusions : (B) 4 with pyogenic effusions : (C) 15 with idiopathic effusions : (D) 9 with malignant effusions. The results were as follows ; 1) The mean ADA activities assessed in pericardial effusions were 134.0+/-77.6U/L in group A : 93.8+/-43.8 in group B : 38.3+/-23.2 in group C : 27.3+/-20.8 in group D. Comparing the level achieved in group A with all others, the difference is significant at the P<0.001 level. 2) The mean ADA activities assessed in sera were 50.7+/-57.2 U/L in group A : 63.5+/-24.1 in group B : 25.9+/-12.0 in group C : 14.0+/-7.5 in group D. Comparing the level achieved in group A with all others, there is no significant difference. 3) Specificity(0.87) and sensitivity(0.93) of the test for the differential diagnosis of patients with tuberculous effusion from those with idiopathic effusion is high, when a value of more than 50 U/L is considered. In conclusion, the assessment of ADA in pericardial effusions is of great value in the diagnosis of tuberculous pericarditis.

Here, we report a case in which the rapid diagnosis of tuberculous pericarditis was made using Mycobacterium tuberculosis (MTB)-specific interferon-gamma release assay on peripheral blood and pericardial effusion. Acid-fast bacilli staining, mycobacterial culture, and nucleic acid amplification targeting MTB using pericardial fluid were negative. However, elevated adenosine deaminase (ADA) activity in pericardial fluid and interferon-gamma release assay positivity in both pericardial fluid and peripheral blood indicated the presence of tuberculous pericarditis. After anti-tuberculous and steroid treatment, the patient's clinical symptoms improved, and pericardial effusion has not reoccurred.

BACKGROUND/AIMS: The prognostic impact of empirical anti-tuberculous management according to adenosine deaminase (ADA) levels in patients exhibiting pericardial effusion (PE) has not been established. We evaluated the appropriateness of ADA-guided anti-tuberculous medication for patients with PE. METHODS: From 2001 to 2010, 47 patients with PE and who were diagnosed with either tuberculous pericarditis (TbP) or idiopathic pericarditis (IP) were enrolled. The diagnosis of definite TbP was made by the presence of Tb bacilli or caseous granuloma in pericardial tissue or effusion. The diagnosis of probable TbP was made by the presence of one or more of the following: (1) elevated ADA (> or = 40 IU/L) in pericardial fluid, (2) positive Tb interferon test, or (3) extracardiac presence of Tb. All clinical information was collected by medical record review and telephone contact. RESULTS: Among the 47 patients with PE, 12 were diagnosed with definite TbP; 17, with probable TbP; and 18, with IP. The mean ADA level was significantly higher in patients with definite TbP than in patients with IP (74.97 +/- 36.79 vs. 20.14 +/- 7.39 IU/L; p < 0.001). The optimal ADA cutoff value for diagnosis of definite TbP was 64 IU/L. The median follow-up time was 12.1 months (range, 0.17-100 months). In patients with low levels of ADA (< 40 IU/L), the incidence of death or recurrence did not different between patients who were prescribed anti-tuberculous medication and those who were not. CONCLUSIONS: The ADA level in pericardial fluid was useful for making a rapid diagnosis of tuberculous pericarditis. Even in tuberculosis-endemic areas, patients with ADA < 40 IU/L may have a good prognosis without empirical anti-tuberculous treatment.

We report here an unusual case of pericardial tuberculoma that was misdiagnosed as thymic carcinoma on an imaging study. A 48-year-old woman was referred for evaluation of an anterior mediastinal mass. Computed tomography (CT) scans of the chest displayed cystic masses mimicking thymic carcinoma at the anterior mediastinum. Pericardiotomy and surgical drainage of the cystic masses were done, and pathologic examination of the excised pericardial specimen showed a chronic granulomatous inflammation with necrosis, compatible with tuberculosis. Acid-fast bacilli were also identified in the specimen. After treatment with anti-tuberculosis drugs and steroids, the patient showed clinical improvement. Although tuberculous pericarditis usually presents as pericardial effusion or constrictive pericarditis, it can also present as a pericardial mass mimicking thymic carcinoma on CT. Therefore, we suggest that tuberculous pericardial abscess should be included in the differential diagnosis of a mediastinal mass in Korea, with intermediate tuberculosis prevalence.
