Abstract
- Osmotic myelinolysis is a distinctive clinical syndrome with a characteristic "bat wing" MRI lesion in the central pons, which is also called central pontine myelinolysis (CPM). However, demyelinating lesions are not only limited to the central pons, but also may be involved in the extrapontine regions including the basal ganglia, thalamus, and cerebellum (extrapontine myelinolysis; EPM). We report an atypical case of osmotic myelinolysis confined to the pyramidal tract from the precentral gyrus to the central pons via the corona radiata and internal capsule in a MR image.
