Follow-up study made approximately 9 months after initial MR:
Right-sided multiple areas of white matter edema mixed with leukodegenerative changes, peripherally confluent with cortical sparing. Partial regression compared to the previous study. One such small region involving left frontal lobe.
Multiple nodular cortical/subcortical foci of gadolinium enhancement with some angiocentric areas in the white matter - moderate partial resorption.
On DWI there are areas of residual higher signal compatible with white matter lesions without any signs of true restriction diffusion on the ADC map.
More prominent multiple foci of chronic microhemorrhages on SWI in places of contrast enhancement.
Impression:
Moderate partial regression with complete remission of the acute changes, with higher degree of hemorrhagic component.
