Primary Choroid Plexus Papilloma of the Cerebellopontine Angle with Spinal Leptomeningeal Seeding

ABSTRACT

A case of primary choroid plexus papilloma of the cerebellopontine angle with spinal leptomengeal seeding is reported, and the literature pertinent to this subject reviewed. CT scan revealed a well-demarcated elliptical homogeneousely high density lesion with definite contrast enhancement within right cerebellopontine angle, which could hardly be differentiated from that of acoustic neurinoma.
