Figure 2. Magnetic resonance images and operative photos of Case 2. Cerebellar hemorrhage, (A) as a low-intensity mass in T2-weighted image (T2WI), became smaller in size (B). The associated high-intensity mass on the left cerebellopontine angle in T2WI showed little change in size 13 months later, which lead to the surgical procedure. The retrocerebellar cavity wall was thin and fairly vascularized (C), while the wall on the side of the cerebellar tentorium was partially thickened (D). The cavity was located in the intra-arachnoid layer (E). The cavity wall of the left cerebellopontine angle was resected, but the cavity size showed no change (F).
