Isolated omental duplication cyst with respiratory epithelium & pancreatic glands: Case report & review of literature

摘要

Duplication cysts are uncommon congenital anomalies. They are usually in communication with or are attached to an adjacent segment of bowel. Rarely are they completely isolated from the gastrointestinal tract. To date, there have been 29 reported cases of non-communicating or isolated duplication cysts. Few contain respiratory epithelium and pancreatic glands. Patients may present with pain, an acute abdomen, bleeding or malignant degeneration. Differential diagnoses for an isolated cystic mass should include duplication cyst in the pediatric population. Recognition and awareness of these anomalies and their various presentations can aid in management. The unusual case of an isolated duplication cyst containing respiratory and pancreatic tissue, found within omentum, is presented with a review of the literature.
