Abstract
A 69-year-old man with presumed solid gastric mass determined by computed tomography,
endoscopic ultrasonography, and fine-needle aspiration underwent videoscopic excision
of what resulted in a cystic structure consistent with intra-abdominal esophageal
duplication cyst. Esophageal duplication cysts are rare congenital lesions that are
difficult to diagnose. They seldom occur entirely below the diaphragm, and occurrence
in adults is unusual. Only six such cases are reported in the literature. When diagnosis
is made, treatment decisions are not always straight forward, although excision is
frequently pursued. The current case describes this unique finding and presents laparoscopic
excision as a safe treatment alternative.
