Temporal Brain MRI Changes From Extrapontine Myelinolysis to Central Pontine Myelinolysis: A Case Report.

We present a case that was initially misdiagnosed as drug-related extrapyramidal side effect. However, after the suspected causative drugs were withdrawn, the patient's condition did not improve. Neuroimaging revealed osmotic demyelination syndrome with a temporal pattern of change from extrapontine myelinolysis to central pontine myelinolysis. Given the limited literature on this rare condition, further research to support clinical diagnosis and treatment is needed.
