Intraluminal contrast; a hint for the diagnosis of communicating type colonic duplication cyst

Abstract

Duplication cyst is a congenital anomaly of gastrointestinal system. Although it is a benign lesion, in some cases it causes obstruction by either itself or due to intussusception. We present a pediatric case with recurrent intussusception due to colonic duplication cyst. Although the duplication cyst showed typical sonographic features, it had intraluminal high density due to passage of oral contrast which is a clue to put the diagnosis of communicating type duplication cyst.
