Gastric duplication cyst in an adult: case report.

Duplication cysts of the stomach are uncommon findings in adult patients and diagnosis is often overlooked. Presenting symptoms are often non-specific, but complications, including chronic infections, ruptures or carcinoma arising in the cyst, are rare. We report a case of a non-communicating cyst of the stomach in a 67-year-old man. Gastric duplication cysts (GDCs) are uncommon congenital anomalies and are rarely diagnosed in adults. Alimentary tract duplication cysts most frequently affect the ileum (35%), the oesophagus (19%), the jejunum (10%), the stomach (9%) and the colon (7%) (1). In 35% of patients, GDCs coexist with other congenital abnormalities such as annular or heterotopic pancreas, or vertebral anomalies such as spina bifida (2). On consideration of the fact that these cysts are usually asymptomatic or, in any case, have no specific signs and symptoms, diagnosis is frequently made post-operatively (3). We present a case of a non-communicating cyst of the stomach in a 67-year-old man, and describe the endoscopic appearance, as well as findings on computed tomography (CT) and pathological examination.
