Pedunculated hepatic hemangioma may be confused with pedunculated hepatocellular carcinoma (HCC) in clinical practice because of their similar ultrasonographic pattern. We report two cases of asymptomatic pedunculated hepatic hemangioma. Both patients presented with intraabdominal masses of unknown nature measuring about 5 cm in diameter. Pedunculated HCC was suspected because of a pedicle and ultrasonographic pattern in both patients, positive hepatitis B surface antigen as a risk factor in one patient, and the high prevalence of HCC in Taiwan. Diagnosis was established by computerized tomography, magnetic resonance imaging, radionuclide scintigraphy, and angiography in both patients and confirmed by histopathology of the surgical specimen in one patient. Pedunculated hepatic hemangioma should be included in the differential diagnosis of a mass located in the upper abdomen.
在临床实践中，带蒂肝血管瘤可能因其超声图像模式相似而与带蒂肝细胞癌（HCC）相混淆。我们报告两例无症状带蒂肝血管瘤病例。两名患者均表现为性质不明的腹腔内肿块，直径约5厘米。由于两名患者均有蒂和超声图像模式、其中一名患者乙肝表面抗原阳性作为危险因素以及台湾地区HCC的高发病率，故怀疑为带蒂HCC。两名患者均通过计算机断层扫描、磁共振成像、放射性核素闪烁扫描和血管造影确诊，其中一名患者经手术标本的组织病理学证实。带蒂肝血管瘤应纳入上腹部肿块的鉴别诊断。
