Secondary trigeminal neuropathy and neuralgia resulting from pontine infarction.

Trigeminal neuropathy and neuralgia are most commonly caused by vascular compression. Only 9 cases of trigeminal neuropathy and neuralgia due to pontine infarction have been reported in medical literature. A 68-year-old man presented numbness and sharp pain on the right side of his face. Magnetic resonance imaging showed a wedge-shaped lesion without mass effect adjacent to the root entry zone of the right trigeminal nerve. This is a rare report on a case of pontine infarction causing secondary trigeminal neuropathy and neuralgia.
