case_images: Sagittal T1-weighted brain images showed no cerebellar atrophy at age 54 (one year before surgery) (A); mild cerebellar atrophy, predominantly affecting the anterior lobe and superior part of the posterior lobe of the vermis, was observed approximately 6 months post-surgery (B); by age 71, moderate diffuse cerebellar atrophy was observed (C). Axial T2-weighted image shows the resection cavity on the dorsolateral side of the left cerebellar hemisphere with adjacent gliosis in the left cerebellar hemisphere (D), and confluent supratentorial periventricular white matter abnormalities on T2 FLAIR (E). Coronal T1 after administration of gadolinium contrast shows a small and stable residual meningeoma (F)

case_images: Brain MRI revealed a small and stable residual cerebellar meningioma on the left side, a surgical resection cavity on the dorsolateral side of the left cerebellar hemisphere with adjacent gliosis in left cerebellar hemisphere extending into the vermis, extensive non-specific supratentorial periventricular white matter abnormalities (WMA) (Fig. 1), and atrophy of the anterior lobe and superior part of the posterior lobe of the cerebellar vermis.
