title: Hepatic angiomyolipoma mimicking hepatocellular carcinoma.
abstract: Angiomyolipoma [AML] is a rare benign lipomatous tumour of the liver. It is typically echogenic on ultrasound, hypodense on computed tomography and hyperintense on magnetic resonance imaging. Its varied imaging appearance is due to the different proportion of the three cell types which make up the tumour. This is a case report of a hepatic AML mimicking hepatocellular carcinoma [HCC] with fatty change in a hepatitis B carrier. Diagnostic difficulty and implications on subsequent management are discussed in the context of an endemic region for HCC.
