Neurinoma of the trigeminal root presenting as atypical trigeminal neuralgia: diagnostic values of orbicularis oculi reflex and magnetic resonance imaging. A case report.
A case of trigeminal root neurinoma presenting as atypical trigeminal neuralgia was reported. The orbicularis oculi reflex was absent on the affected side, but reappeared after operation. The demonstration of the tumor was much clearer on magnetic resonance imaging. The usefulness of these electrophysiological and radiological studies in differentiating varied entities of trigeminal neuralgia is stressed.
