Biliary cystadenoma is a very rare benign cystic tumour of the liver. Fewer than 150 cases have been described in the literature so far. The authors present a case of a 29-year-old female with a giant intrahepatic biliary cystadenoma who presented with abdominal pain and obstructive jaundice. The patient was treated with left hepatectomy and now 12 months after the surgery she is in good condition with no signs of recurrence of the disease. Clinical presentation of biliary cystadenoma is not specific. Diagnosis is based on imaging methods, mainly ultrasound and CT scan. However, it is often misdiagnosed. For treatment, radical resection is advocated because a biliary cystadenoma is considered to be a premalignant lesion. The prognosis of biliary cystadenoma after complete resection is excellent. Nevertheless, there is a risk of recurrence or malignant transformation after incomplete resection.
