Central Pontine Myelinolysis

Axial T2 shows increased signal centrally in the pons. Axial, sagittal and coronal T1 with Gd show enhancement of those regions with sparing of the corticospinal tracts. The term Central Pontine Myelinolysis (CPM) is now preferably named as Osmotic Demyelination Syndrome (ODMS) due to common association with rapidly corrected hyponatremia. As a radiologist I prefer the CPM name as it is more anatomic specific about the location of the findings. However do not forget the term ODMS when looking for it in the textbook index.
