Ectopic liver (EL) is a rare congenital anomaly characterized by the presence of a mass composed of hepatic tissue localized in a different anatomical location with no connection to the native liver. Usually an incidental finding, EL can rarely cause symptoms such as abdominal pain due to torsion, intraperitoneal bleeding, compression, obstruction, or neoplastic transformation, both benign and malignant. EL is often suspected after instrumental investigations such as ultrasound, CT and MRI, however a definitive diagnosis is necessarily bioptic. Here we report a case of a 22-year-old Italian female patient with acute abdominal pain, who underwent abdominal ultrasound, CEUS with Sonovue®, CT scan and ultrasound-guided biopsy which raised the suspicion of hepatocellular adenoma (H-HCA). After a laparoscopic excision of the lesion a diagnosis of H-HCA was formulated.
