The role of ultrasonography in gallbladder duplication

Gallbladder duplication is a rare congenital biliary malformation that occurs during the fourth and fifth embryonic week in about one in 4000 births. it may be diagnosed incidentally or during radiological investigation to symptoms associated with cholelithiasis and cholecystitis. Surgery of both structures is indicated only in symptomatic patients and in these cases pre-operative diagnosis is essential to prevent possible complication. Surgery is not recommended for asymptomatic double gallbladder. We describe a case of asymptomatic gallbladder duplication and we assess the role of ultrasonography.
