title: Epidermoid tumor presenting with trigeminal neuralgia and ipsilateral hemifacial spasm: a case report.
abstract: A case of epidermoid tumor presenting with a painful tic convulsif was reported. A 35-year old male with trigeminal neuralgia and ipsilateral hemifacial spasm was diagnosed as having an epidermoid by CT and metrizamide CT cisternography and the symptoms were completely eliminated after the operation. In this case, metrizamide CT cisternography was very useful for preoperative diagnosis by demonstrating the characteristic findings of the epidermoid. It should be taken into consideration that there are some cases with trigeminal neuralgia and/or hemifacial spasm whose symptoms are due to brain tumors.
