Abstract:
Diverticula of the oesophagus are rare. They can occur at any
level, and are often defined by their anatomical location. Three
categories are recognised, namely pharyngo-oesophageal,
parabronchial and epiphrenic. Although these diverticula are
often asymptomatic, patients can develop significant problems
with dysphagia, regurgitation and aspiration. The causation of
oesophageal diverticula is controversial; however, the popular
current belief is that most occur because of oesophageal
dysmotility. This paper demonstrates the categories of
oesophageal diverticula pictorially, including the radiological
features and underlying pathology.
