摘　　要：目的：分析肝脏不典型血管瘤的 CT 征象。方法收集20例经病理证实的肝脏不典型血管瘤患者的资料,所有患者均行 CT 平扫及增强扫描,分析其不典型的 CT 征象。结果20例患者共24个不典型病灶。其中21个病灶为类圆形,3个病灶形态不规则。14个病灶中心可见瘢痕、坏死,其中2个病灶内可见钙化灶。20例中2例可见包膜皱缩。增强扫描13个病灶边缘明显强化,延迟期病灶未完全填充；2个病灶动脉期均匀强化,门静脉和/或延迟期持续强化；4个病灶动脉期中心斑片状强化,门脉期和/或延迟期从中心向周边反向强化；3个病灶为动脉期边缘轻中度强化；2个病灶动脉期病灶边缘无强化,门脉期和/或延迟期可见轻度强化。2例合并动静脉瘘。结论当肝血管瘤有或合并不典型表现时,需注重细微征象,全面观察,综合分析,以便给出正确诊断及鉴别诊断。Objective To analyze the CT characteristics of atypical hepatic hemangiomas.Methods 20 patients with atypical hepatic hemangiomas confirmed by pathology were collected.All patients underwent plain and contrast-enhanced CT scan and the atypical CT findings were analyzed retrospectively.Results There were 24 lesions in 20 patients,among which 21 lesions were round in shape and 3 lesions were irregular.Scars and necrosis were found in 14 lesions,calcifications in 2 lesions and capsule contractions in 2 lesions.Contrast-enhanced CT showed significant peripheral enhancements with incomplete fill-in in delayed phase in 13 lesions, homogeneous enhancements in arterial phase and continuous enhancements in portal and /or delayed phase in 2 lesions,central patchy enhancements in the arterial phase and reverse enhancements from center to edge in portal and/or delayed phase in 4 lesions, mild to moderate peripheral enhancements in the arterial phase in 3 lesions,and no enhancements in the arterial phase and mild enhancement in portal and/or delayed phase in 2 lesions.In addition,2 cases had arteriovenous fistulas.Conclusion As for atypical hepatic hemangioma,it is necessary to comprehensively observe and analyze the delicate signs for correct diagnosis and differential diagnosis.
