=====Choroid plexus papilloma in the posterior fossa=====

see also [[Fourth ventricle choroid plexus papilloma]].

[[Choroid plexus]] [[papilloma]]s in the [[posterior fossa]] can present with different clinical signs and symptoms. 

One patient, who had a [[fourth ventricle]] papilloma, experienced unsteady gait and episodes of [[dizziness]] over many years. The tumor was cystic an calcified, and adherent to the [[brainstem]]. The second patient had only signs of [[raised intracranial pressure]]. A soft tumor was located in the [[cerebellomedullary cistern]]. The third patient, with a papilloma in the [[cerebellopontine angle]], complained of hearing loss. This tumor was firmly adherent to the dura mater and looked exactly like a meningioma. The appearance on computed tomography scan, the macroscopic aspect, and the vascular supply of a papilloma in the posterior fossa can vary considerably
