Coexistence of tuberculous constrictive pericarditis and right atrial tuberculoma: a case report.

Tuberculous constrictive pericarditis is a rare condition with a high mortality rate. The coexistence of constrictive pericarditis and intracardiac tuberculoma has not previously been reported. We report the case of a 65-year-old man presenting with left-side pleural effusion and signs of systemic venous congestion for 2 months. Echocardiography and computerized tomography showed a thickened pericardium and a mass in the right atrium. Pericardiectomy and excision of the right atrial mass were performed. Pathologic examination of the pericardium and the right atrial mass both revealed chronic granulomatous inflammation with acid-fast bacilli and confirmed the diagnosis of tuberculous constrictive pericarditis and right atrial tuberculoma. This case reminds us of the possibility of this type of rare combination of tuberculous constrictive pericarditis and intracardiac right atrial tuberculoma, and the need for complete imaging studies when such cases are encountered.
