title: Multifocal choroid plexus papillomas: case report.
abstract: Choroid plexus papillomas (CPP) are rare tumors of the central nervous system, usually occurring in the ventricular system. Apart from spinal drop metastases, CPPs are generally unique tumors. In this report, the authors present two exceptional adult cases involving multiple benign CPPs located in both intra- and extraventricular locations. The tumors were located in the fourth ventricle and Meckel's cave in one case and the cerebellopontine angle, the frontotemporal region and the fourth ventricle in the other. A review of the literature revealed that these two cases represent the first reported occurrences of multiple choroid plexus papillomas involving Meckel's cave and frontotemporal intraparenchymal locations.
