Huge Mesenteric Cyst in a 7 years old boy

A 7 years old boy presented with history of pain abdomen and abdominal distention for 8 months. On examination, the child’s abdomen was hugely distended with presence of fluid thrill. CT scan of the abdomen showed presence of a large cystic mass occupying the entire abdomen and compressing all other organs. The child was prepared and taken for surgery, intraoperatively the cyst was found to be arising from the mesentery of the sigmoid colon, which is a very rare location for the origin of a mesenteric cyst. The cyst was very meticulously dissected preserving all the blood vessels supplying the sigmoid colon and was successfully removed completely. Postoperative recovery was uneventful and the child was discharged on 4^th postoperative day.
