Hepatic hemangiomas (HH) are the first cause of benign hepatic tumors, their prevalence varies from 3% to 20% in general population.1 Giant HH are those greater than 4 cm; they account for only 10% of all HH. HH are usually asymptomatic. Computed tomography (CT) and magnetic resonance image (MRI) characteristic finding is the centripetal enhancement of contrast.2 Histological characteristic findings are spongy appearance with blood filled vascular channels lined by endothelium; thrombi are frequent.3 Surgical treatment (resection or enucleation) is recommended in symptomatic patients.1

A 56-year-old woman was evaluated because she suffered for systemic arterial hypertension, but she also complaints for heartburn, occasional abdominal discomfort, and abdominal distension. A distended abdomen and a large mass were noted by palpation. Abdominal ultrasound revealed a tumor of the liver. Contrast enhanced CT and MRI confirmed characteristic features of giant HH (Figures 1-2). Blood count cells and liver tests were normal. Enucleation was performed without complications. Histology confirmed diagnosis of HH (Figure 3). She is being asymptomatic at 12 months of follow up.
