Teratoma of Lesser Omentum

A one-year-old female child presented with antenatally detected lump in the abdomen on USG which was gradually increasing in size. On USG, it was reported as a suspected case of gastric duplication cyst. So, to confirm the diagnosis CECT of abdomen was done. On CT scan it turned out to be a case of Teratoma of the lesser omentum of size 7cm X 6cm, with areas of calcification resembling teeth, with close proximity to common bile duct, portal vein, hepatic artery and the stomach wall.

Patient was subsequently taken up for surgery and after 4 long hours of precise and delicate dissection, the tumor was removed without damaging any of the surrounding structures. Postoperative period was uneventful and the child was discharged on 5^th postoperative day.
