摘　　要：目的总结单发巨块型肝脏婴儿型血管内皮瘤的CT表现,以期提高对该病的诊断水平。方法回顾性分析12例单发巨块型婴儿型肝脏血管内皮瘤的CT表现,所有的病例均经穿刺或手术病理证实。结果 12例CT检查,平扫肿瘤均呈低密度,7例肿瘤中央内见更低密度灶,8例肿瘤内见钙化;增强扫描动脉期11例肿瘤边缘呈结节样、环形、花瓣样强化,其中10例病灶同时出现自边缘向中心呈粗条索状强化影,强化程度接近同层腹主动脉,有1例病灶出现全瘤均匀强化;门静脉期强化进一步扩大,向心性强化;延迟期有5例全瘤强化,其中3例病灶密度稍高于正常肝实质,2例病灶密度与正常肝实质基本相等,有7例病灶中央更低密度区始终无强化。结论单发巨块型婴儿型肝脏血管内皮瘤的CT表现有一定的特征性。Objective To analyze the CT appearance of solitary giant infantile hepatic hemangioendothelioma. Methods CT of 12 patients with histologically cortfirmed solitary giant infantile hepatic hemangioendotheliomas was reviewed. Results CT showed hypodense masses in all patients with centers of lower densities （7） and calcifications （8）. Peripheral, nodular, floral pattern of contrast enhancement in the arterial phase was seen in 11 patients and centripetal cord-like contrast enhancement was seen in 10 patients. The tumor enhancement was isodense relative to the abdominal aorta. Homogeneous enhancement o[ the entire tumor in the arterial phase was found in one patient. All tumors showed progressive enhancement in the portal venous phase with enhancement of the entire tumorsinthedeoayedphase（5patients）toslightoyhigher（3）orequal（2）densitiesrelativetothenormallivertissues. Conclusions CT appearance of solitary giant infantile hepatic hemangioendothelioma is characteristic.
