Brain MRI. Coronal view of gadolinium-enhanced FLAIR images and sagittal view of plain FLAIR images throughout treatment.
On day 3, coronal images showing leptomeningeal enhancement over the sulcus of the left parietal lobe. Enhancement gradually improves. Axial FLAIR images from day 11 showing multiple linear high signals in the bilateral basal ganglia, cerebellum, and thalamus. Multiple linear high signals in the bilateral basal ganglia, thalamus, and cerebellum are resolved (days 18 and 39).
MRI, magnetic resonance imaging; FLAIR, fluid-attenuated inversion recovery.
