Neuroradiologic findings in pontine and extrapontine myelinolysis

Contrast enhancement on MRI in the early phase of central pontine myelinolysis

Three days after symptom onset, T2-weighted MRI showed a hyperintense lesion of the pons (A) and of the basal ganglia (B). Coronal postgadolinium T1-weighted MRI showed a nonhomogeneous enhancement of the pontine lesion 3 days after symptom onset (C), which diminished 15 days later (D).
