Abstract

The more common manifestations of cryptococcal infections are restricted to the central nervous system and lungs. A young man, suffering from idiopathic dilated cardiomyopathy with a left ventricular ejection fraction of 20%, presented with subacute, painful tender swelling in both legs initially attributed to congestive cardiac failure. No response to diuretics was achieved. Metabolically active lesions in the muscles of both lower limbs suggestive of muscle abscesses were found. A diagnosis of tropical pyomyositis was therefore made, but aspiration surprisingly revealed gram-positive yeast cells, staining of which on India ink and culture confirmed Cryptococcus. A good response to a combination of liposomal amphotericin B and flucytosine was obtained, but nevertheless the patient died from heart failure after induction of antifungal therapy.
