Choroid plexus papilloma in the posterior cranial fossa MR, CT, and angiographic findings

In this study, we reviewed the magnetic resonance (MR, n = 5), computed tom ography (CT, n = 3), and angiography (n = 3) of six patients with pathologi cally confirmed choroid plexus papilloma (CPP) in the posterior cranial fos sa. CPPs in the posterior cranial fossa have several features, including a propensity to arise at the foramen of Luschka with extraventricular extensi on, occasional peritumoral signal voids/cysts or calcification, weaker enha ncement on MR or CT, and less strong tumor staining by the anterior or post erior inferior cerebellar artery or angiography.
