Abstract

Congenital cysts of the gallbladder are extremely rare, hence only a few ciliated foregut cysts of gallbladder have been reported. We report a case of a 20-year-old woman presenting with mild right upper quadrant abdominal discomfort, with normal levels of serum bilirubin and liver function tests. Abdominal ultrasonography revealed a well-defined cystic mass measured about 2 cm attached to the neck of gallbladder, with internal echogenic debris suggesting a complicated cyst, such as a hemorrhagic cyst. Abdominal computed tomography and magnetic resonance cholangiopancreatography revealed similar findings. Laparoscopic cholecystectomy showed a slightly distended gallbladder. The size of cyst on the neck was 1.6x1.2 cm, and it contained mucosa lined by ciliated pseudostratified columnar epithelium and underlying smooth muscle layers. Histopathology identified a ciliated foregut cyst of gallbladder.
