title: Primary choroid plexus papilloma of the cerebellopontine angle presenting as brain stem tumor in child.
abstract: A case of a primary choroid plexus papilloma of the cerebellopontine angle in an 8-year-old female is presented. The clinical features of progressive cranial nerve palsies and cerebellar signs in the absence of intracranial hypertension initially suggested an intrinsic brain stem lesion. Whereas a radionuclide brain scan demonstrated abnormal uptake in the region of the pons, vertebral angiography and pneumoencephalography were diagnostic of an angle mass. At surgery, the tumor proved to be a choroid plexus papilloma that was totally confined to the cerebellopontine angle. This patient represents the thirteenth reported case of a primary cerebellopontine angle papilloma and the first such case occurring in a child.
