颅内非典型海绵状血管瘤的CT和MRI分析

目的提高颅内非典型海绵状血管瘤的CT和MRI正确诊断。方法回顾分析12例颅内非典型海绵状血管瘤的CT和MRI，并与手术病理进行对照。在12例病人中，11例作CT检查，10例作MRI检查，CT和MRI同时检查9例。结果本组12例中，1例位于鞍内，1例位于四脑室内，5例位于脑内，4例位于中颅窝，1例位于后颅窝。出现脑水肿3例、囊变1例，伴脑出血4例。本组定位诊断100%，定性诊断，11例错误，1例未作定性诊断。结论非典型海绵状血管瘤定性诊断较困难，应强调影像学与临床综合分析。

CT and MRI Analysis of Intracranial Atypical Cavernous Angiomas

Objective:To improve the CT and MRI diagnostic accuracy of intracranial atypical cavernous angiomas(ACA).Methods:We retrospectively analyzed CT and MRI appearances,operative and pathological findings of 12 cases with ACA.Of them,11 cases were seanned by CT,10 cases by MRI and 9 by both CT and MRI.Results:Of 12 cases:One case as located at the sella ,1 case was at the fourth ventricle,5 cases were located at the cerebral hemisphere,4 cases were located at the middle cranial fossa and 1 case was at the posterior cranial fossa.There was edema in 3 cases,1 case had cystic component and 4 cases had cerebral hemorrhage.The localized rate of ACA by CT and MRI was 100%,but 11 cases were misdiagnosis and 1 case did not made the qualitative diagnosis. Conclusion:The qualitative diagnosis of ACA have some difficulty,so that the emphasis should be on the analysis of the combination imagiology and clinic.
