Oesophageal pouches and diverticula: a pictorial review.

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.

Primary tuberculosis of the breast: a rare cause of a breast lump.

Primary tuberculosis (TB) of the breast is a very rare condition. We present a 50-year-old patient who presented with primary TB of the breast. The significance of the radiological findings, the importance of histological diagnosis and treatment, and the possibility of co-existence with breast cancer are discussed.
