Pyopericardium with Cardiac Tamponade in a Nigerian Child with Acute Osteomyelitis.

In pyopericardium, pus accumulates in the pericardial space as a result of infection by pyogenic organisms, most common of which are Staphylococcus aureus and Mycobacterium tuberculosis. These patients are at risk of cardiac tamponade. Apart from pericardiocentesis in the management of these patients, definitive drug treatment may pose a formidable challenge in a setting of coinfection as in patients with tuberculosis who are predisposed to secondary bacterial infections. This was the case of our patient. We here highlight the challenges faced with etiologic diagnosis in resource-limited settings.
