Painful tic convulsif: case report.

A case with painful tic convulsif is presented. A 77-year-old woman had developed trigeminal neuralgia 12 years before admission and ipsilateral facial spasm 2 years before admission. Upon operation, the superior cerebellar artery was found to impinge upon the entry zone of the fifth nerve. In addition, the anterior inferior and posterior inferior cerebellar arteries were found to bend along the seventh nerve. Teflon sheets were placed between the nerves and offending arteries. She has been pain-free and spasm-free for the past 18 months. Pathomechanism of the association of the multiple compression syndromes and the treatment are discussed.
