Epigastric mass in a young girl: trichobezoar. Imaging diagnosis.

A 16-year old girl presented with a history of abdominal pain, lump in epigastrium since one year. The ultrasound examination showed an epigastric mass, which was delineated as a filling defect in the stomach on barium studies. Upper GI endoscopy showed a large intragastric mass composed of hair. The CT scan showed a gastric mass extending to the duodenum. She was managed by surgical removal. A large gastric trichobezoar extending upto the jejunum was found. This case highlights the characteristic radiological appearance on barium, ultrasound and computed tomography of a bezoar within the stomach and a trichobezoar with a long tail extending upto the jejunum without intestinal obstruction is unusual.
