Figure 3: (a) Medulloblastoma: Small round cells with scanty cytoplasm and hyperchromatic nuclei (smear) (b) FS: Sheets of small round cells. Inset: FFPE (c) Lateral ventricular Central Neurocytoma: Smear showing tumor composed of uniform population of round to oval cells arranged loosely (smear) (d) FS shows a low grade tumor. Inset: FFPE. (e) Cerebellar Hemangioblastoma: Poorly spread smear composed of cohesive oval/spindle stromal cells with areas of haemorrhage (smear preparation) (f) FS shows a vascular tumor composed of closely spaced capillary sized vessel separated by stromal cells. Inset: FFPE
