目的：探讨肝海绵状血管瘤结节样强化的ＣＴ表现特征。材料与方法：回顾性研究１９８８年１０月至１９９６年２月经手术、病理证实的肝海绵状血管瘤６３例，９２个病灶。对于“结节样强化”分别从增强程度（相对于同一扫描层面腹主动脉）、分布进行观察。结果：８３％的病灶显示结节样强化，其中７７％的结节样强化与同一扫描层面接近等密度。结论：结节样强化是ＣＴ诊断肝海绵状血管瘤的特征性表现。
Objective: To investigate the CT features of nodular enhancement in hepatic cavernous hemangiomas. MATERIALS AND METHODS: Retrospective study of 63 cases of cavernous hemangioma and 92 lesions confirmed by surgery and pathology from October 1988 to February 1996. For “nodular enhancement”, observe the degree of enhancement (relative to the abdominal aorta at the same scan level) and distribution. Results: 83% of the lesions showed nodular enhancement, with 77% of nodular enhancement similar to the same scan plane. Conclusion: Nodular enhancement is a characteristic feature of CT in the diagnosis of hepatic cavernous hemangiomas.
