Complete enclosure of gall bladder inside the lesser omentum - a rare anomaly.

Gall bladder is known for many congenital anomalies such as duplication, intrahepatic position, floating position etc. Most of its anomalies can be detected in ultrasound examination and radiography. We report an extremely rare congenital anomaly of gall bladder as observed in a male cadaver during dissection classes. The gall bladder was totally enclosed in the right free margin of the lesser omentum, in front of the usual contents of the right free margin of lesser omentum. The size, shape and blood supply of the gall bladder were normal. Though this anomaly might not cause any functional disturbances, it might result in complications during laparoscopic cholecystectomy.
