A 4-year-old boy presented with progressive imbalance, right-side hemiparesis and spasticity. Initial MRI (Fig. 1) demonstrated volume loss of the left cerebral hemisphere, widening of the sulci (arrows) and high signal of subcortical white matter (arrowheads), particularly the parietal lobe. Follow-up MRI 6 months later (Fig. 2) showed mild progression of the volume loss (arrows) and white matter changes (arrowheads). Findings were consistent with chronic encephalitis – most likely Rasmussen encephalitis. The diagnosis was confirmed by cerebral biopsy.
