Cecal duplication cyst associated with a malfixed right colon presenting as an abdominal mouse in an infant causing a diagnostic dilemma

Abstract

Duplication cysts (DCs) of the cecum are extremely rare anomalies. A DC causing luminal obstruction and presenting as a recurrent intestinal obstruction in infants is quite a rare occurrence. They usually present with a palpable lump, but when associated with malrotation, can result in a diagnostic dilemma. We report a rare case of a cecal DC associated with a malfixed right colon presenting with a wandering intra-abdominal lump and recurrent intestinal obstruction, resulting in a diagnostic dilemma in an infant.
