A noncontrast (a) and contrast-enhanced (b) magnetic resonance imaging showing a large well-defined lobulated mass epicentered in the trigone occipital horn and body of left lateral ventricle showing intense homogeneous enhancement, suggestive of choroid plexus tumor

(a) Cellular smear composed of round-to-oval atypical cells, mostly singly scattered and in syncytial clusters, showing mild pleomorphism with eccentrically placed nuclei, finely granular chromatin, inconspicuous nucleoli, nuclear membrane indentation, and moderate to abundant amount of pale cytoplasm (Giemsa, x200); (b) occasional mitotic figure is noted interspersed with few tumor cells (Giemsa, x400); (c) Papillary fragment of the tumor with fibrovascular core is noted (Papanicolaou, x400); (d) Section showing cellular tumor composed of cells mainly in sheets with focal papillary pattern (H and E, x400)

Further, the tumor was surgically removed, and histopathological examination of tumor showed partly autolyzed cellular tumor composed of cells mainly in sheets with focal papillary pattern [Figure 2d]. Occasional mitotic figure (<2/10 high-power field) was noted along with foci of necrosis and part of brain parenchyma.
