Subacute Polymicrobial Bacterial Pericarditis Mimicking Tuberculous Pericarditis: A Case Report.

BACKGROUND Bacterial pericarditis can present a diagnostic challenge due to the difficulty of obtaining tissue for bacterial identification. This report is of a 34-year-old man who presented with fever and cough. Diagnosis was initially delayed without a tissue sample, but the patient was later found to have polymicrobial bacterial pericarditis.
