[Bile liver cyst: diagnostic and therapeutic challenge]

Hepatic biliary cysts (HBCs) are benign cystic formations of the liver, often discovered incidentally on imaging. They are mainly classified as simple hepatic cysts (KHBS) and complex hepatic cysts (KHBC). Asymptomatic in the majority of cases, they become symptomatic when adjacent structures are compressed or when there is a complication with the cyst itself. Diagnosis is based on ultrasound, supplemented by CT scan and/or MRI to confirm the nature of the cyst and its relationship with surrounding organs. Asymptomatic forms do not require follow-up. In the case of complicated symptoms and/or cysts, multidisciplinary management is essential.
