The Medial Pontine Mid-Tegmentum Syndrome.

Isolated pontine infarcts are common and are often associated with well-described syndromes that are classified based on their specific clinical presentation and arterial stroke territories. Here we present a case of acute combined diplopia and unilateral lower extremity sensory abnormality. Diffusion-weighted magnetic resonance imaging revealed a punctate area of acute ischemia in the right medial pontine mid-tegmentum. These findings suggest a unique pontine stroke syndrome characterized by acute ischemic injury at the intersection of the medial lemniscus and cranial nerve VI.
