Lateral pontine tegmental hemorrhage presenting as isolated trigeminal sensory neuropathy

A 45-year-old man awoke with numbness and paresthesias on the right side of his face, scalp, ear, and tongue. CT and MRI demonstrated a focal hemorrhage in the dorsolateral right pontine tegmentum. Cerebral angiography was negative for vascular malformation or aneurysm. CT performed 1 month later showed complete resolution of the pontine hematoma, with residual minimal lateral pontine atrophy.
