Esophageal Duplication Cyst

Unknown Chest Case 1


50 y/o man with abdominal pain.

Image Findings

Oval well circumscribed superior mediastinal mass adjacent to the esophagus. High intensity on T2-weighted image and low intensity on T1-weighted image. No spinal abnormalities were seen. Esophagogram (not shown) showed smooth extrinsic mass effect on right side of upper esophagus.

Differential Diagnosis


Esophageal duplication cysts may be found incidentally for work up of unrelated symptoms as is likely in this case. Occasionally, gastric mucosa within the cyst may result in bleeding. Neurenteric cysts are usually associated with skeletal abnormalities.
