Gallbladder duplication is a rare anatomic anomaly characterized by the presence of an accessory gallbladder. There is no increased risk for malignancy or calculi compared to a single gallbladder.

Epidemiology

Prevalence is estimated at 1 in 4000 live births .

Classification

Boyden's classification divides gallbladder duplication into three groups:

  • bilobed, incomplete gallbladder division with one common cystic duct
  • complete gallbladder duplication with separate cystic ducts that lead to a common hepatic duct
  • complete gallbladder duplication with a common cystic duct entering the common hepatic duct

Its classification is more easily applied today using MRI, since ultrasound does not always allow adequate visualization of the cystic duct.

Differential diagnosis

Imaging differential considerations include:
