Hepatic Sclerosing Cavernous Hemangioma Mimicking a Malignant Liver Tumor：Report of a Case

Abstract

A 72 years old woman was found to have diagnosed by computed tomography（CT）with a tumor in the left lobe of the liver and referred to our hospital. Abdominal ultrasonography showed a 106mm tumor with calcification in the left of the liver. Computed tomography（CT）showed it to be a tumor with ring enhancement. Magnetic resonance imaging（MRI）showed it to have a low signal on T1-weighted and high signal on T2-weighted images. Positron emission tomography（PET）was not remarkable. Abdominal angiography showed no tumor stain but slightly enhanced in the edge and inside of the tumor. We suspected a benign liver tumor, but couldn’t exclude the possibility of a malignant liver tumor. Left hepatic lobectomy was conducted. The histological examination of the liver tumor revealed to be a hepatic sclerosing cavernous hemangioma. We report a case of the rare tumor which was mimicking a malignant liver tumor.
