Oesophageal duplication cyst

Dr Henry Knipe and Dr Aditya Shetty et al.

Oesophageal duplication cysts are a type of congenital foregut duplication cyst.

Less common compared to other foregut duplication cysts. There may be an increased male predilection 5.

Patients are generally asymptomatic but may complain of dysphagia due to oesophageal compression. They typically present in childhood. 

They are a congenital malformation of the posterior primitive foregut and results from aberration of the posterior division of the embryonic foregut at 3-4 weeks gestation. They are commonly lined by gastric epithelium. This ectopic gastric mucosa is prone to infection, perforation and haemorrhage.

Location

It mainly occurs within the thoracic oesophagus 4.

Plain radiograph

Well defined soft tissue density in close association with the oesophagus.

Fluoroscopy

On barium swallow the cyst may cause extrinsic compression of the oesophagus.

CT

Well defined thick walled structure (fluid density) noted along the oesophagus.

MRI
  • T1: low to intermediate signal intensity
  • T2: high signal intensity

Recognised complications include carcinoma arising within the cyst 5.

For uncomplicated cysts consider:

For complicated cysts (e.g. with haemorrhage/necrosis) the differential can be broader and can include:
