Colonic perforation presenting as retroperitoneal abscess: case report and brief review of literature
Keywords:Retroperitoneal abscess, Colon perforation, Retrocecal appendix
Retroperitoneal colonic perforation is a rare cause of retroperitoneal abscess. It presents more frequently in frail elderly patients with heterogeneous signs and symptoms which make it difficult to diagnose clinically. Subcutaneous emphysema with pneumomediastinum and iliopsoas muscle abscess are unusual signs. Abscess formation occurs in 0.3 to 0.4% and is the second most common complication of perforated lesions. Acute appendicitis may also present with retroperitoneal abscess which is a life threatening complication.
