Abstract

Cerebral lesions can cause dermatomal sensory deficit. The most commonly reported site is the medulla oblongata due to its well-separated sensory systems. Dermatomal sensory deficit that has developed after pontine infarctions have been reported in several cases, the majority of which involved the medial lemniscus. However, restricted spinothalamic sensory loss has rarely been reported in pontine infarctions. We report herein a patient who presented with dermatomal spinothalamic sensory deficits below the tenth thoracic level after pontine infarction. Key Words: Pontine infarction, Dermatomal sensory deficit, Spinothalamic tract
