MR Findings of Choroid Plexus Papilloma: Case Report
Abstract
- PURPOSE
Choroid Plexus papilloma is a rare intracranial neoplasm that is most commonly found in the trigone of the lateral ventricle in children or in the fourth ventricle in adult. Extraventricular extension of choroid plexus papilloma has been rarely reported within the cerebellopontine angle (CPA) cistern. Authors report two cases of choroid plexus papilloma in the posterior fossa seen on magnetic resonance imaging (MRI).
MATERIALS AND METHODS
MRI findings of two cases of choroid plexus papilloma in posterior fossa were retrospectively reviewed.
RESULTS
In the first case, the tumor was in the fourth ventricle and extended to the left CPA cistern via the foramen of Luschka. In the second case, the tumor presented as an expansile mass of the of fourth ventricle and right lateral recess. Multiple signal voids of low intensity due to prominent feeding vessels and calcifications within the tumors were noted.
CONCLUSION
This report demonstrates MR findings of choroid plexus papilloma in the posterior fossa with the brief review of the literatures.
