Completely Isolated Enteric Duplication Cyst Presenting as an Inguinal Hernia

ABSTRACT

Enteric duplication cysts are uncommon congenital anomalies whose embryogenesis remains unknown. We report here on an isolated enteric duplication cyst, that presents as an inguinal hernia. A 21-year-old woman was admitted with a month-long history of a palpable mass in the left groin. Radiologically, a computed tomography scan revealed a 3.5 x 2.5 cm sized cystic mass in subcutaneous layers of the left suprapubic area. Microscopically, the cystic wall resembled gut wall. The wall was composed of two distinct muscle layers with the presence of Auerbach's plexus. On examining the entire sections of the cyst wall very carefully, no epithelial lining was found on the inner surface. The submucosa was slightly fibrotic. The diagnosis was a completely isolated enteric duplication cyst.
