title: Pontine infarcts and hemorrhages.
abstract: Pontine infarcts are often part of a large ischemia involving the brainstem, although infarcts may be restricted to the pons. In both cases, infarcts in the pons are characterized by interesting clinical patterns resulting from a variety of cranial nerve dysfunctions, eye movement disorders and motor, sensory and cerebellar manifestations, either isolated or in combination. The anteromedial and anterolateral territories are the most commonly involved. Penetrating branch artery disease is the most common etiology. Ten percent of all intracerebral hemorrhages are located in the pons, and small hemorrhages in this brainstem structure may, in some instances, give rise to unusual clinical manifestations.
