Isolated renal mucormycosis: an unusual cause of acute renal infarction in a boy with aplastic anaemia.

Mucormycosis is an opportunistic fungal infection occurring most often in immunocompromised patients. The most common clinical presentation of infection with the fungus is rhinocerebral, followed by primary pulmonary, disseminated, gastrointestinal and cutaneous manifestations. Renal involvement in disseminated mucormycosis is well described, however, there are only few case reports describing the isolated renal mucormycosis in literature. We present an unusual case of renal mucormycosis in a patient of aplastic anaemia who presented with right flank pain and, on imaging, was found to have renal infarction and thrombosis of renal vessels. Histopathology revealed fungal hyphae infiltrating the entire kidney, renal vessels and perinephric space.
