Abstract
A 74-year-old woman who visited a doctor regularly for hypertension, underwent abdominal ultrasonography (US) that revealed a liver tumor ; she was referred to our hospital for further evaluation. US showed a homogenous well-demarcated tumor (size, 17 mm) with low echnogenicity in the hepatic segment 2. Abdominal computed tomography (CT) showed that the marginal area of the tumor was mainly enhanced in the arterial phase, and the central area was heterogeneously enhanced in the equilibrium phase. Gadolinium ethoxybenzyl magnetic resonance imaging (Gd-EOB-MRI) revealed a tumor with low intensity in the T1-weighted image and high intensity in the fat-saturated T2-weighted image. The strong enhancement in the marginal area and slight enhancement in the central area of the tumor in the arterial phase was also revealed by MRI. 18-Fluorodeoxyglucose positron emission tomography (FDG-PET) showed no abnormal FDG uptake. The patient underwent lateral segmentectomy for possible malignant liver tumor. Intraoperative examination revealed a relatively soft grayish-white tumor. Histological findings revealed significant elastic and collagen fiber proliferation with hyalinization around sclerosed small blood vessels ; the condition was diagnosed as sclerosed hemangioma of the liver. We report this case and discuss the treatment for lesions mimicking hepatic cancer.
