title: Isolated trigeminal sensory change due to pontine hemorrhage.
abstract: Isolated trigeminal sensory change has been rarely described as a manifestation of pontine hemorrhage. We report a 31-year-old man who developed sudden and long-lasting trigeminal sensory disturbances. Brain magnetic resonance imaging showed a hemorrhage in the right lateral pontine tegmentum corresponding to the trigeminal sensory nucleus, and the venous phase angiogram demonstrated abnormal vascular structures. Pontine hemorrhage secondary to venous malformation can be one of the causes of isolated trigeminal sensory change.
