Subacute tuberculous pericarditis with fibroelastic constriction diagnosed upon pericardiectomy.

A patient with subacute pericarditis showed no evidence suggesting tuberculosis until pericardiectomy was performed because of hemodynamic deterioration. The excised pericardium had a rubbery fibroelastic consistency; histologically, there were granulomatous changes characteristic of tuberculosis. Although tuberculous pericarditis is a difficult diagnosis, this case illustrates the diagnostic and therapeutic importance of early pericardiectomy before myocardial inflammatory infiltration occurs together with end-stage pericardial fibrosis and calcification.
