Choroid plexus papilloma in the posterior fossa

see also Fourth ventricle choroid plexus papilloma.

Choroid plexus papillomas 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 1).
