Foregut duplication cyst

Case contributed by Dr Alexandra Stanislavsky

Patient Data

Age: Adult

Incidental finding on CT.  In the posterior mediastinum, to the left of the esophagus and below the level of the carina is a low attenuation (20 HU), non-enhancing mass which abuts and displaces the esophagus to the right side. Appearance and location are suggestive of foregut duplication cyst.


Subsequent MRI of the chest demonstrates a well-defined posterior mediastinal mass intimately related to the esophagus. There is T1 and T2 hyperintensity and no enhancement. 

Appearances are in keeping with a foregut duplication cyst.
