Abstract:
The authors report two cases of epidermoid cyst in the cerebellopontine angle which presented as trigeminal neuralgia. The tumors were surgically removed by suboccipital craniectomy. The cysts were densely adherent to multiple cranial nerves, including the trigeminal nerve, and the tumors occupied adjacent cisterns. After removal of the cystic content, it was sometimes difficult to differentiate the tumor capsule from the arachnoid membrane. In one patient, trigeminal neuralgia was resolved immediately after the operation, while for two weeks postoperatively, the other suffered severe headache and facial dysesthesia due to aseptic meningitis. To avoid surgical complications, it is resonable to leave a minute capsule attached to cranial nerves or blood vessels.
