Perforated Littre's hernia diagnosed on imaging: case report and review of literature.

We report the clinical details and imaging findings of a case of perforated Littre's hernia presenting as lower abdominal wall cellulitis in a 50-year-old male. Findings included herniation of an oral contrast opacified blind-ending pouch arising from the anti-mesenteric border of the distal ileum into the right inguinal canal, with extravasation of oral contrast. There were adjacent inflammatory changes with subcutaneous emphysema extending up to the right anterior chest wall. Meckel's diverticulum is rarely diagnosed preoperatively on imaging. We highlight the importance of computed tomography in imaging Meckel's diverticulum.
