    Abstract:
    The aim of the study was to assess the role of different diagnostic procedures in the recognition of malignant pericarditis. Consecutive medical records of the patients with pericardial effusion treated with pericardiocentesis or pericardioscopy in the period of 1982-2002 were analyzed retrospectively. Criteria of neoplastic pericarditis were: positive result of pericardial fluid cytology and/or neoplastic infiltration found in pericardial biopsy specimen. Criteria of non-neoplastic pericarditis were: negative result of pericardial fluid cytology and pericardial biopsy specimen, no neoplastic disease diagnosed at presentation and during 3-years of follow up. Malignant pericarditis was diagnosed in 47 patients (pts), nonmalignant in 51. Echocardiographic signs of cardiac tamponade were found in 80% of pts with neoplastic pericarditis and 40% of pts with non-malignant disease (p = 0.0001). Chest CT scan revealed the presence of enlarged mediastinal lymph nodes in 94% of pts with malignant pericarditis and only 11% of pts with non-malignant disease (p = 0.00001). Pericardial thickness on CT scan exceeded 8 mm in 75% of the pts with malignant pericarditis and 8% of pts with nonmalignant disease (p = 0.0003). Pericardial fluid (pf) CEA concentration was significantly higher in the patients with neoplastic pericarditis than in the pts with non-malignant process. CEA > 5 ng/ml and Cyfra 21-1>50 ng/ml were found in 43% of the pts with malignant pericarditis and none of the pts with benign pericarditis. Thus we recommend chest CT scan and pericardial fluid tumor markers (CEA and Cyfra 21-1) assessment as the procedures helpful in the recognition of malignant pericarditis.
