Most cases of liver hemangioma are asymptomatic and discovered incidentally on liver ultrasound or computed tomography scan. Giant cavernous hemangioma (GCH) are however clinically distinct from smaller asymptomatic ones and may be confused with primary or metastatic malignancy. Symptomatic GCH of the liver are rare. The aim of the study was to show the rare case of symptomatic giant cavernous hemangioma of the liver which may be confuse with primary or metastatic malignancy. The patient’s images (abdominal ultrasound and computed tomography scans) and case file were reviewed and summarized. The subject matter of giant cavernous hemangioma was reviewed in the literature. The index case was discussed and compared with literature. We report a 42-year-old man who presented with a 2-year history of right upper abdominal pain and 6-month history of chest pain. No history of jaundice, body swelling or previous history of blood transfusion. No history of smoking or alcohol consumption. The patient is a known diabetic. Abdominal ultrasound scan showed hepatomegaly with a huge well defined oval shaped mixed echogenic mass lesion with lobulated margins occupying 4th and 5th segments of liver, measuring 84.9×111 mm in size suggestive of adenoma. The remaining hepatic parenchyma was normal. No intrahepatic biliary dilatation was seen. Initial histological examination revealed adenoma. Repeat histology done later however revealed hepatitis. Abdominal CT scan was later carried out and showed hepatomegaly but with no discernible mass lesion on precontrast images. Contrast enhanced images however, showed a fairly rounded mass lesion with peripheral enhancement and delayed filling-in at the venous phase, seen in the superior aspect of the right lobe extending to the dome. The intrahepatic vasculature and biliary ducts are not dilated. A diagnosis of cavernous hemangioma was made based on criteria of delayed (centripetal) filling-in. The patient however was lost to follow up. Hepatic hemangioma can be giant and symptomatic and despite its rarity, may still be encountered in practice.
