New MRI data suggest Rasmussen encephalitis causes changes in the “unaffected” hemisphere

Takeaway

  • Significant changes occur in the contralesional hemisphere in Rasmussen encephalitis (RE) that are currently unaccounted for in standard diagnostic tools.

Why this matters

  • These MRI data suggest that volumetric-based computation of the hemispheric ratio is not sufficient for progression monitoring of RE as it can’t account for the complex grey matter (GM) alterations in the disease.
