A Rare Case of an Extensive Multi-compartment Epidermoid Presenting with Pure Motor Trigeminal Neuropathy, Case Report and Review of Literature

Epidermoid cysts are benign slow-growing tumors, clinical signs and symptoms at the time of presentation are related to the location and extent of the lesion. The motor fibers of the trigeminal nerve are fairly resistant to extraneous compression. Intracranial lesions in the vicinity of the trigeminal nerve usually present with sensory symptoms without affecting the motor component. We report a rare case of a middle cranial fossa epidermoid presenting with pure motor trigeminal neuropathy.
