 Abstract
Peliosis Hepatis (PH) is a rare vascular disorder of the liver, characterized by the presence of cystic blood-filled cavities distributed throughout the hepatic parenchyma. The pathogenesis of PH remains controversial. The preoperative diag-nosis of PH is difficult, due to the non-specific imaging characteristics of PH and almost all cases are diagnosed on histology post resection. This study presents a case of PH masquerading as hepatocellular carcinoma (HCC). The patient is a 45-year old Chinese lady, who presented with transaminitis. She was found to be hepatitis B virus core total antibody-positive with an alpha-fetoprotein (AFP) of 29.4 ng/ml. Triphasic liver computed tomography showed sev-eral arterial hypervascular lesions and hypoenhancing lesions on the venous phase, particularly in the segments 6/7. Subsequently, a magnetic resonance imaging scan showed multiple lesions in the right hemiliver with an indeterminate enhancement patterns. Subsequently, she decided to undergo a resection procedure. Histopathology revealed findings consistent with PH with some unusual features. This case demonstrates a clinical conundrum, in which PH presented with a raised AFP, in a patient with risk factors for the development of HCC. The clinical suspicion of PH should be high in patients, who present with multiple hepatic lesions with variable enhancement patterns. (Ann Hepatobiliary Pancreat Surg 2017;21:157-162)
