Multiple gallbladders
Updates to Article Attributes
Body
was changed:
Gallbladder duplication is a rare anatomic anomaly characterised 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 30004000 live births 3.
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:
- gallbladder diverticulum
- gallbladder fold
- Phrygian cap
- choledocal cyst
- focal region of pericholecystic fluid
- focal adenomyomatosis
- intraperitoneal fibrous bands (Ladd bands)
- a dilated cystic duct remnant
