Reperti
- Heterogeneous, nonenhancing mass in the left cerebellar hemisphere which is mildly T2 hyperintense relative to the adjacent cerebellar parenchyma
- Mild diffuse diffusion signal hyperintensity (largely representing T2 shine-through)
- Associated mass effect on the inferior aspect of the fourth ventricle
- Right cerebellopontine angle meningioma
- Diffuse dural thickening and enhancement, likely related to chronic shunting
- Right parietal approach ventriculostomy catheter traverses the right lateral ventricle
