ABSTRACT
Objective To evaluate the usefulness of MR cisternography in epidermoids of the cerebellopontine angle (C-P angle).Methods The findings of MR cisternography of epidermoids of the C-P angle in 19 cases confirmed by surgery were analysed retrospectirey.The signal intensity of tumors,the effect on nerves and vessels by tumor were evaluated.Results MR cisternography depicted tumors as slight-medium hypointense (n=19) to CSF. 84% of patients had involvement of the trigeminal nerves (n=16); 42% of patients had involvement of the facial nerve and the acoustic nerve (n=8); 26% of patients had involvement of the internal carotid artery (n=5); 21% of patients had involvement of the vertebral-base artery (n=4). Conclusion MR cisternography contributes to show the anatomic details of the C-P angle and clearly depicte the relationship between tumors and nerves as well as vessels. Thus it can provide useful informations for the presurgical planning and approach of C-P angle epidermoids.
