Pericardial effusion

Discussion:

A pericardial biopsy was performed which showed nonspecific fibrinopurulent pericarditis, with no evidence of malignancy. Cytology on the pericardial fluid showed only inflammatory cells. A Mycobacterium tuberculosis polymerase chain reaction test was negative. Culture for TB is negative to date.

The causes of fibrinous pericarditis include: viral; acute idiopathic; tuberculous; pyogenic; acute rheumatic fever; myocardial infarction; chronic renal failure; connective tissue diseases; malignant neoplasms (lymphoma, thymoma, mesothelioma, metastases); cardiac trauma or surgery; and radiotherapy.
