Kyste epidermoide intracranien

Introduction: Aim : To evaluate the value of magnetic resonance imaging (MRI) in the diagnosis of 2 cases of epidermoid cysts. Materieal and Methods: 2 cases of histopathologically proven epidermoid cysts were studied. All patients were examined with conventional MRI (T1WI, T2WI, FLAIR) and Diffusion-weighted imaging (DWI). Results: the lesions were located in the right cerebellopontine angle and the right temporal fossa. All lesions were hyperintense on T2, hypointense on T1and strikingly hyperintense on DW. Conclusion: New MR techniques such as FLAIR and DWI are most helpful tools in the specific preoperative diagnosis which is important for surgical guidance.
