Barium esophagography showed a well defined filling defect arising from the anterior left side of the distal esophagus (Fig. 1).
Chest CT scan shows a homogenous, low density mass anterior to the intra-abdominal esophagus.

The chest computed tomography (CT) scan revealed a unilocular cystic mass, measuring 4x3 cm, and it was not enhanced by contrast dye (Fig. 2).
The defect of the muscular layer is shown in the intra-abdominal esophagus (arrow). During the procedure, there was no injury to the mucosal-submucosal layer.

The mass was then successfully enucleated without any injury to the mucosal-submucosal layer (Fig. 3).
Microscopic finding of the cyst wall shows a two-layered muscle coat, and the lining epithelium is pseudo-ciliated columnar cells (HE, x40).

The cyst wall contained a two-layered muscle coat (Fig. 4) and the surface of the lumen was covered by a lining of pseudo-ciliated columnar epithelium.
The follow-up barium esophagography shows no leakage or stenosis in the distal esophagus.

Upon follow-up barium esophagography performed on 6th postoperative day, there was no leakage or stenosis in the distal esophagus (Fig. 5).
