RENAL cortical abscess (renal carbuncle) is an uncommon disorder that may be associated with a variety of clinical and pathological complications. These have included perforation (with or without fistula formation) into contiguous areas such as the peritoneal cavity, perinephric space, and renal pelvis.1 Peritonitis, perinephric abscess, and urinary tract infection or obstruction may follow. Chronic renal cortical abscess may also closely mimic renal neoplasms and occasionally be responsible for prolonged fever of unknown origin.
Recently, we cared for a patient with a renal cortical abscess in whom a massive retroperitoneal hemorrhage developed. Bleeding appeared to result from abscess erosion into the renal vasculature. This case illustrates an unusual and catastrophic complication of a visceral abscess.
