Chest pain and abdominal pain for many years.

Patient Data

Age: 32
Gender: Male
Modality: CT

Oral contrast only looking if oesophagus connects to cyst. Not present.

Double density over right atrium. Learn interfaces.

Modality: X-ray

2 years prior. Subtle double density with an extra interface lateral to right of spine.

Modality: CT

A well defined cyst in the distal foregut is seen. A few years later it is bigger and inflamed and has developed a thick wall.

6 years prior. I do not see the double density here clearly, probably there but smaller.

-    One lymph node, negative for malignancy (0/1).

-    Enteric duplication cyst with exuberant acute and chronic     inflammation.
-    No malignancy identified.

EGD: Extrinsic mass in distal esophagus compressing on distal oesophagus.

1.    A distal right mediastinal paraesophageal mass consistent with duplication cyst. 
2.    Thick walled cystic mass. 
3.    The entire cystic mass was intramural.
4.    No esophageal mucosal/submucosal communication or disruption was noted of the normal esophagus when tested with insufflation intraluminally using a nasogastric tube.
