简要总结
cephaloceles are rare lesions of the petrous apex, inconsistently listed as meningoceles or arachnoid cysts. They're consistent with a herniation posterolateral of the Meckel cavum within the petrous apex. These lesions may be the cause of a symptomatology varied, or be discovered by chance in subjects who have not been asymptomatic. Currently, there is no evidence in the literature a simple, fast and reproducible radiological marker that allows for the diagnosis of cephaloceles of the petrous apex, in particular the small ones. The purpose of this study is to validate a radiological benchmark simple and reproducible, the trigeminal petrol line, in order to improve the diagnosis of petrous apex cephaloceles

Validate a radiological landmark allowing MRI diagnosis cephaloceles of the petrous apex
时间窗: Files analysed retrospectively from from January 01, 2003 to September 31, 2020 will be examined
This mark corresponds to the projection of a line drawn on an axial section, in the plane of the posterior roots of the trigeminal nerves, between the anterior and external edges of the petrous apex along the petro-trigeminal angle on each side.
