Intramural bronchogenic cyst of the oesophagus: a rare entity.

Bronchogenic cysts are congenital cystic lesions of foregut origin, usually intra-pulmonary or mediastinal in location. Peri-oesophageal bronchogenic cysts are rare, while intra-oesophageal cysts are almost always considered as enterogenous owing to their location and their composition. We report here an unusual case of a young adult with an intramural bronchogenic cyst causing dysphagia. Despite the fact that the cyst was completely embedded in the oesophageal wall, the pathological findings revealed the respiratory origin of the cyst. An extramucosal excision of the cyst was performed establishing the diagnosis and alleviating all our patient's symptoms.
