Colon duplication combined with mature teratoma-a case report

Abstract

Gastrointestinal duplication is an uncommon congenital abnormality, and colonic duplication combined with teratoma has rarely been reported. A 24-year-old man presented to the Emergency Department with a sudden onset of severe abdominal pain lasting 2 hours without intermission, and also complained to have who had chronic constipation since his birth. Multislice CT imaging showed 2 masses in the retroperitoneal space. The one huge cystic mass was detected behind the transverse colon, pancrease and stomach without infi ltration into the surrounding tissues. The right mass containing soft tissues and bones pushed aside the inferior vena cava and right kidney. The cystic duplication and the right mass were excised separately. This case indicates that a patient diagnosed as colonic duplication should receive further differential diagnosis to identify if it coexists other diseases, especially the teratoma.
