Dermoid cyst of the mesentery in an infant

Abstract

7 months old male child presented with abdominal distension since birth. On examination there was a lobulated, tense cystic mass occupying almost 2/3 of the abdominal cavity. Ultrasonography (USG) revealed a predominantly hypoechoic mass measuring 17cm x 14cm x15cm. CT scan of abdomen showed a multiseptate cystic mass with eccentrically located areas of fat and calcification. Exploration of the abdomen revealed a huge thick walled cyst within the leaves of the mid ileal mesentery which could be enucleated out entirely after careful dissection. Histopathology suggested it to be a benign cystic teratoma (Dermoid cyst).
