Primary renal aspergillosis and renal stones in both kidneys associated with hematopoietic stem cell transplant

Invasive aspergillosis (IA) is a leading cause of infectious mortality in patients who have undergone a hematopoietic stem cell transplant (HSCT); the mortality due to IA ranges from 70% to 93% in HSCT patients. Early diagnosis and treatment are the cornerstones for the good prognosis of IA. Primary renal aspergillosis is an extremely rare presentation in patients who have undergone HSCT, and the risk factor for this uncommon presentation is not well known. We report a patient who developed primary renal aspergillosis and renal stones in both the kidneys after HSCT. Invasive renal aspergillosis was diagnosed after a nephrectomy, which was performed to treat massive renal hematoma.
