Features such as high mitotic rate, marked necrosis, nuclear atypia and solid growth are considered as malignancy indicators for choroid plexus neoplasms (RIBAS et al., 1989; KOESTNER & HIGGINS, 2002).
It should be pointed out, however, that TTR is not entirely specific for choroid plexus neoplasms, since TTR immunoreactivity has been documented in several other neoplasms, retinal pigment epithelium, and hepatocytes.[7] Additionally, primary extraventricular locations for choroid plexus-derived lesions are uncommon, with only one such tumor described arising in the suprasellar region.[8] There is a possibility that our tumor may have in fact arisen from the floor of the third ventricle; however, this seems unlikely given the extensive bony erosion of the sella and the fact that no definite intraventricular component was demonstrated.
