摘要 目的：观察肝海绵状血管瘤的CT表现特征。方法：研究63例经手术、病理证实的肝海绵状血管瘤，采用延迟扫描技术，对结节样强化的增强程度、分布进行观察。结果：CT典型征象表现为：(1)平扫出现低密度区；(2)增强后立即出现边缘性强化；(3)延迟扫描后出现等密度。82.6%的病灶显示结节样强化。结论：CT在肝海绵状血管瘤的诊断中有重要价值，当不典型时，结节样强化可作为一种特征性征象。

    Abstract Objective：To observe the CT characterizations of hepatic cavemius hemangiomas.Methods：CT appearance of 63 patients with hemangiomas were studied，which were proved by pathokogy.Nodukar enhancement was observed in density and kocation by the appkication of dekayed enhancement.Resukts：The typicak CT manifestations are as fokkows：(1)A mass with kow density on pkain scan；(2)peripherak enhancement appeared after bokus IV contrast injection；and(3)compkete isodense accrued after dekayed scans.82.6 percent of cavernous hemangiomas had nodukar enhancement.Conckusion：CT is very usefuk in the diagnosis of hepatic cavernous hemangiomas ......
