Vascular tethering of the megaoesophagus by the azygos arch masquerading as a malignancy.
We report the case of a 50-year-old male, a known case of achalasia cardia for 15 years, who after being successfully treated earlier by pneumatic dilatation, presented with recurrent dysphagia due to vascular tethering of the megaoesophagus by the azygos arch simulating a malignant oesophageal stricture. The patient underwent oesophagectomy because of our inability to rule out the possibility of a malignancy developing in the mid-portion of the long-standing megaoesophagus. We wish to highlight the existence of this new clinical entity and the diagnostic as well as therapeutic dilemmas posed by it.
