肝巨大血管瘤较少见,容易与原发或转移肝癌混淆。本文报告18例最大直径在7 cm以上的肝巨大血管瘤的动态CT结果。CT平扫见低密度的肿瘤病灶内有多种形态的更低密度区,动态扫描此区始终不强化。所有病例均有不同程度边缘强化及向心性充填,但无1例完全填满。5例表现不典型,强化灶少而小,延迟至15 min 仍有相当部分未成等密度。对不典型病例的诊断及动态 CT技术问题作了讨论。
Hepatic giant hemangiomas are rare and are easily confused with primary or metastatic liver cancer. This article reports the dynamic CT findings of 18 cases of hepatocellular giant hemangiomas with a maximum diameter of 7 cm or more. On plain scan of CT, there are multiple forms of lower density regions in low-density tumor lesions, and dynamic scans in this region have not been enhanced. All cases had marginal enhancement and centripetal filling at different levels, but none was completely filled. In 5 cases, the performance was not typical, and the enhanced focus was small and small, and there was still a considerable portion of unequal density after a delay of 15 minutes. The diagnosis of atypical cases and dynamic CT techniques were discussed.
