Imaging analysis of metaplastic meningioma misdiagnosed as intracranial chondrosarcom: 1 case report

摘要:
目的探讨化生性脑膜瘤及典型脑膜瘤、颅内软骨肉瘤的影像学差异。 方法通过1例化生性脑膜瘤误诊为颅内软骨肉瘤的病例，分析二者CT、MRI上的差异及误诊原因。 结果化生性脑膜瘤CT、MRI特点均不明显，容易跟软骨肉瘤混淆。 结论化生性脑膜瘤的影像诊断主要依据不在肿瘤本身，而在脑外征象。 Abstract:ObjectiveTo explore the imaging differences between the metaplasia meningioma and the typical meningioma and intracranial chondrosarcoma. MethodsA case of metaplastic meningioma misdiagnosed as intracranial chondrosarcoma was analyzed. The differences in CT and MRI and the cause of misdiagnosis were analyzed in two cases. ResultsThe characteristics of the CT and MRI of the metaplasia meningioma were not obvious. It was easy to confuse the chondrosarcoma. ConclusionThe imaging diagnosis of metaplasia meningioma is not mainly based on the tumor, but on the external brain. -
