Demographics:
58 years old, Male
Indication:
Left-sided weakness
Findings
CT
- Areas of hypoattenuation in the anterior right basal ganglia/anterior limb of the right internal capsule and in the right frontal subcortical white matter with mild corresponding local mass effect
MRI
- Multifocal areas of parenchymal restricted diffusion involving the bilateral cerebral and cerebellar hemispheres
- The largest lesion is located in the anterior right basal ganglia/anterior limb of the right internal capsule, which measures 3 x 2.5 x 2.3 cm, demonstrates peripheral enhancement which is incomplete along its ependymal margin, and demonstrates central restricted diffusion
- Linear enhancement extends along the superior margin of the right lateral ventricle
- Many of these lesions demonstrate peripheral susceptibility artifact
- Surrounding vasogenic edema, particularly involving the right basal ganglia and right frontal subcortical lesions
- No substantial midline shift or evidence of herniation or hydrocephalus
