Esophageal cyst in the duodenum of a foal

Abstract

A 21-day-old Thoroughbred colt was euthanized following a history of recurrent colic. A 4.5 cm in diameter, occlusive, submucosal cyst was identified in the duodenum at necropsy. Histologically, the cyst was surrounded by a smooth muscle wall and was lined by both squamous and attenuated cuboidal to columnar epithelium. A diagnosis of an esophageal cyst was made based on the gross and histologic findings.

Surgical resolution of an oesophageal duplication cyst causing regurgitation in a domestic shorthair cat

“…An oesophageal duplication cyst has been reported once in a dog, five times in horses and once in a crab-eating macaque (cynomolgus monkey). [1][2][3][4][5][6][7] Duplication cysts have been reported in the lower gastrointestinal tract in cats. 8,9 They are a recognised phenomenon in humans, although they are considered to be very rare.…”

Duplication Cysts in the Oesophagus and Pylorus of a Juvenile Grey Seal (Halichoerus grypus): A Case Report

“…1 Anatomical location and size of duplication cysts determines the associated clinical signs, if any occur. Oesophageal duplication cysts have been reported in humans, 2 domestic species [3][4][5][6][7][8] and in a cynomolgus macaque. 9 Dysphagia and regurgitation are the most frequent clinical signs associated with oesophageal duplication cysts in humans and nonhuman species.…”

“…9 Dysphagia and regurgitation are the most frequent clinical signs associated with oesophageal duplication cysts in humans and nonhuman species. [2][3][4][5][6][7] Pyloric duplication cysts have been reported in humans but to the authors' knowledge, not yet in other species. Persistent vomiting is the most frequent clinical sign associated with pyloric duplication cysts and other duplication cysts near the pylorus in humans due to gastric outflow obstruction.…”
