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]

Differentiating [disease name] from other diseases on the basis of [symptom 1], [symptom 2], and [symptom 3]

On the basis [symptom 1], [symptom 2], and [symptom 3], [disease name] must be differentiated from [disease 1], [disease 2], [disease 3], [disease 4], [disease 5], and [disease 6].

Diseases Clinical manifestations Para-clinical findings Gold standard Additional findings
Lab Findings Imaging
Confusion Weakness and quadriplegia Speech difficulties Hypoosmotic hyponatremia MRI
Central pontine myelinolysis + ++ ++ ++
  • Symmetric signal intensity abnormality in the central pons at T2-weighted and FLAIR imaging
  • Decreased T1 signal intensity
  • Fluid attenuated inversion recovery (FLAIR) hyperintense lesion in the pons
  • Intramedullary central T2 hyperintensity at axial T2W of spinal cord and sagittal T2W of thoracic spinal cord
 MRI The most common cause of central pontine myelinolysis is rapid correction(>48-hours duration) of hyponatremia in patients with the history of prolonged hyponatremia
