Intestinal Obstruction Caused by a Vitelline Cyst in 28-year-old Male—A Case Report—

Abstract

An adult case of intestinal obstruction caused by a vitelline cyst is reported. A 28-year-old man presented to our hospital because of continuous abdominal pain around the umbilicus. Abdominal enhanced computed tomography showed marked dilatation of the small intestine and a cystic lesion directly under the umbilicus. The cyst was approximately 60 mm in maximal diameter. The preoperative diagnosis was intestinal obstruction caused by a vitelline cyst. intraoperatively, the small intestine was seen to be obstructed by a band-like structure extending from the cyst to the ileum of the oral side, 95 cm from the ileocecum. En bloc resection of the vitelline cyst and the band-like structure was performed. Histological examination of the specimen showed the complete structure of the intestinal wall at the site of the vitelline cyst. Meckel's diverticulum is well known as a form of vitello-intestinal duct remnant, but other forms are rare in adults. This case is presented along with a review of the literature.
