Figure 1: (a) Magnetic resonance imaging T2-weighted axial image showing a welldefi ned hyper intense solid cystic lesion in the region of 4th ventricle, with focal peripheral iso intense areas (b) Sagitial image showing irregular peripheral enhancement of the lesion with central nonenhancing area. (c) Smear cytology of a neoplasm with pilocytic astrocytes, rosenthal fibres,eosinophilic granular bodies (H and E, ×200) (d) Cytology with neurocytic cells around central eosinophilic neuropil (H and E, ×200) (inset a rosetie in smear — H and E, ×400)
