Medial medullary syndrome
Appearance
Medial medullary syndrome (also known as Dejerine syndrome) is a set of clinical features resulting from an infarction in the brainstem. The vessel usually involved is the anterior spinal artery which supplies the medial part of the medulla oblongata.
The condition usually consists of a weakened tongue on the affected side of the brainstem (due to involvement of the hypoglossal nerve), weakness of the limbs on the contralateral (opposite) side (caused by pyramidal tract damage), and a loss discriminative sensitation on the contralateral side (from medial lemniscus involvement).
