Unusual features of gall bladder duplication cyst with review of the literature

Abstract

A 1-month-old female infant presented with a lump in the right hypochondrium extending into the right iliac fossa. Ultrasonography and computed tomography suggested an intestinal duplication cyst or a gall bladder cyst. Exploratory laparotomy revealed it to be a congenital gall bladder duplication cyst without associated complications. It was removed after confirming the presence of a normal gall bladder. The infant's postoperative course was uneventful. This unusual presentation of congenital gall bladder duplication cyst prompted us to report this case.

Duplication of gallbladder — Rare entity treated laparoscopically

“…True duplication of the gallbladder results from the division of a single gallbladder primordium during the fifth or sixth week of embryonic development. Anatomic variants of gallbladder duplication are still differentiated according to Boyden's classification: 1 i. Y-shaped type (the two cystic ducts uniting before entering the common bile duct) ii. H-shaped type (ductular type, the two cystic ducts entering separately into the biliary tree) The incidence and nature of clinical problems associated with duplicated gallbladder are similar to those encountered in the single viscus, including acute or chronic cholecystis, cholelithiasis, empyema, torsion, cholecystocolic fistula and carcinoma.…”

“…Gallbladder duplication is a rare congenital malformation that occurs in about one per 4000 births [1]. Congenital anomalies of the gallbladder and anatomical variations of their positions are associated with an increased risk of complications after laparoscopic cholecystectomy [2][3][4][5].…”

Duplex gall bladder: bystander or culprit

“…The duplex gall bladder is thought to be the result of exuberant budding of the developing biliary tree during the division of the caudal bud of the hepatic diverticulum 5. There is no sex predominance, and most cases are found incidentally during cholecystectomy or at autopsy.…”

Duplicated gall bladder detected on 99m Tc HIDA hepatobiliary scintigraphy: A report of two cases

“…[1] USG may diagnose GB duplication if the viscera are located separately. Differential diagnosis based on sonographic findings include gallbladder diverticula, GB fold, Phrygian cap, choledochal cyst, pericholecystic fluid, focal adenomyomatosis, and intraperitoneal fibrous bands, which results in a diagnostic dilemma.…”
