The authors describe a case of tuberculous cerebral abscess of the frontal lobe that developed 1 year after an episode of acute miliary tuberculosis. The development of such a lesion indicates a persistence of infection and an immunological breakdown which may partly have been due to protein malnutrition.

Suffocation of botfly larvae is favoured to surgical removal, due to the possibility of larval remnants being retained and acting as a nidus for infection. The increasing frequency of exotic travel means doctors need to be more aware of tropical medicine.

This would not necessarily relieve any extrinsic pressure on neighbouring viscera although allowing drainage.One disturbing feature is the presence of a blind oesophageal pouch opening into the stomach. T h e fact that there was at one time free regurgitation indicates that there may be a risk of peptic oesophagitis.As the p H of the gastric juice increases this becomes more likely.Surgical excision of the accessory lower oesophagus can be carried out if necessary through a thoracoabdominal approach. Opening of both cavities would give a better view of the lower end of the blind oesophagus and also would allow a n inspection of the present state of the gastric duplication.Further surveillance of this case will be necessary, particular points to be looked for being anamia, upper abdominal pain, or dysphagia. SUMMARYA case of duplication of the lower oesophagus, stomach, and duodenum is reported. T h e embryological basis for it is discussed and the method of treatment briefly analysed.
