Perforated Right Side Colonic Diverticulum with Abscess

Abstract

Colonic perforation is a rare cause of intraabdominal abscess. It presents, more frequently in frail elderly patients, with heterogeneous signs and symptoms which hamper the clinical diagnosis. Subcutaneous emphysema with pneumomediastinum and  muscle abscess are unusual signs. Colonic  perforation may be consequent to diverticulitis or locally advanced colon cancer. Due to the anatomy of the abdominal space and different physiopathology, diverticular perforation may present with air and pus collection; on the other hand perforated colon cancer may cause groin mass and psoas abscess.
