Overview

On the basis central pontine myelinolysis must be differentiated diseases that cause acute confusion, lethargy, speech difficulties and bilateral weakness or quadriplegia such as: Posterior leukoencephalopathy syndrome, infective encephalitis, ischemic Brain stem infarction, thalamus infarction due thrombosis of the basilar artery, diffuse hypoxic encephalopathy, metastasis to the brain and brain tumors such as glioma.

Differentiating central pontine myelinolysis from other Diseases

On the basis central pontine myelinolysis must be differentiated diseases that cause acute confusion, lethargy, speech difficulties and bilateral weakness or quadriplegia such as:[1][2][3][4][5][6]

Differential diagnosis

Stroke should be differentiated from other causes of muscle weakness and paralysis. The differentials include the following:[7][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]
