Gastric duplication cyst in an adult woman: a case report

Gastric duplication cyst is one of the rarest congenital anomalies of gastrointestinal tract duplications. These are usually diagnosed within the first year of life; however, some cases are diagnosed in adulthood. The diagnosis of these cysts is challenging because symptoms vary depending on their location and are often nonspecific. Definitive diagnosis is achieved through histopathological results. The purpose of this report is to describe a case of gastric duplication in a 71-year-old woman treated at the Regional Hospital in the city of Mérida, Mexico, who underwent exploratory laparotomy for resection of a cyst located in the gastric fundus.
