Primary cerebellopontine angle choroid plexus papilloma: a case report and review of literature.

A case of primary choroid plexus papilloma of the cerebellopontine (CP) angle is described in a 28 years old man. He presented with hearing loss, right facial palsy and spastic quadriparesis (4/5). He also had markedly increased intracranial pressure. CT scan revealed a large high attenuating lesion in right CP angle with gross hydrocephalus. The patient was operated with the clinical and radiological diagnosis of right sided acoustic tumor with brainstem compression. Radical tumour excision was performed, seven days following VP shunt. Patient had immediate postoperative deterioration followed by a steady recovery. The possibility of a secretory choroid plexus papilloma is discussed.
