Cysts of foregut origin.
Biomedica Jan ;12(2):46-8.

Cysts of foregut arise during intra uterine development but do not necessarily communicate with foregut or its derivatives. Common sites are neck, thorax and upper abdomen. Thoracic foregut cysts constitute 10% of mediastinal tumours. Intra abdominal cysts present as gastric or duodenal duplications or rarely as combined gastroduodenal duplication. This rare entity presents with the effects of its mass which vary according to the site e.g. respiratory distress, mass and feeding difficulties.
