Figure 2: Photomicrograph showing a cystic tumor at the cerebellopontine angle (a: Hand E, ×40), consisting of large cystic spaces lined by meningothelial component (b: H and E, ×40) and widespread areas of small, capillary type thin-walled vessels ('microvascular pattern') (c: H and E, ×100) interspersed with foamy cells with vacuolated cytoplasm (d: H and E, ×200). Tumor cells showed immunopositivity for EMA (e: EMA ×200) and Vim (f: Vim ×200)
