Its prevalence has been increasing steadily secondary to wide use of oral contraceptives and due to the increased use of imaging for a variety of unrelated reasons. Large adenomas may present with chronic abdominal pain. As HCA become larger it is prone to rupture and hemorrhage due to central necrosis because the vascular supply is limited to the surface of the tumor. If left untreated HCA can undergo transformation into hepatocellular carcinoma which can be as high as in 10% of cases1 or even higher. Surgical excision is a preferred method of treatment. Other modalities include embolization of bleeding tumors and ablative modalities in selected cases.Keywords: Hepatocellular, adenoma, liver tumour
