title: Congenital bilobed gallbladder with phrygian cap presenting as calculus cholecystitis.
abstract: The incidence of congenital bilobed gall bladder is 1 in 3000 to 4000. A Phrygian cap is a congenital abnormality of the gallbladder with an incidence of 4%. Preferred mode of diagnosis for Phrygian cap is cholescintigraphy and multi phase MRI, as Ultrasonography and CT are not always conclusive. The estimated prevalence of gallstone disease in India has been reported as 2% to 29%. A case of bilobed gall bladder with Phrygian cap in both the lobes and pigment gallstone in one of the lobes presenting as calculus cholecystitis is reported for its rarity and difficulty in arriving at correct preoperaive diagnosis.
