Summary:
- Radiopaedia case ID: 47800
- Image ID: 24906479
- Image stack position: 9/14
- Plane projection: Axial
- Aux modality: ADC
- Study findings: There are widespread areas of T2 hyperintense signal abnormality involving the subcortical white matter in the parasagittal medial parietal lobes, left temporal operculum and occipital subcortical white matter. Further deep grey matter involvement in both thalami is noted along with diffuse pontine signal alteration with extension into the cerebellar peduncles.There is patchy diffusion-restriction around the margin of particularly the left temporal focus.There is no pathological intracranial enhancement following contrast administration.
- Modality: MRI
- System: Central Nervous System
- Findings: There are multiple abnormal areas of low attenuation within both hemispheres which are irregular, some quite confluent, which appear to preferentially affect the white matter. These lesions do not appreciably enhance post contrast. The sulci, basal cisterns and ventricles appear normal. No bulging of the fontanelles. No shift of midline structures or brain herniation. Normal venous sinuses. No acute intracranial hemorrhage or extra-axial collection. Normal appearance of the mastoid air spaces. No destructive bone lesion.
