Wallerian degeneration

Case contributed by Dr Amr Farouk

Presentation

55 years old patient with history of stroke 1 year ago on follow up.

Patient Data

Age: 55 years old
Gender: Male
Modality: MRI

A right cerebral irregular shaped area of CSF-like signal in the right frontoparietal region (subcortical in location) including the Centrum semiovale and right lentiform nucleus with surrounding rim of gliosis eliciting high T2 and FLAIR signal intensities. Associated ex-vacuo dilatation of the right lateral ventricle body, and widening of the overlying cortical sulci and Sylvian fissure. Other bilateral cerebral (frontoparietal) patchy foci of high T2 and FLAIR signal are seen as well exerting no mass effect on the surrounding structures nor surrounded by oedema. Prominence of the remaining ventricular system and extra-axial CSF spaces. 

Evidence of Wallerian degeneration with hyperintensity of the right corticospinal tract from Centrum semiovale through the internal capsule and cerebral peduncle to the level of the medulla. 

Case Discussion

Right cerebral namely frontoparietal region (subcortical in location) including the centrum semiovale and right lentiform nucleus old infarction with hyperintensity of the right corticospinal tract from centrum semiovale through the internal capsule and cerebral peduncle to the level of the medulla. MR findings are of Wallerian degeneration.
