Cerebellopontine angle Choroid plexus papilloma various presentations: report of series and literature review

Abstract Choroid plexus tumors (CPTs) are rare choroid plexus epithelium originated neoplasms. Among all, choroid plexus papilloma (CPP) is the most common type of CPT. Clinical features and signs at diagnosis of CPP in CPA are so extensive and also nonspecific. This work aimed to review the sign and symptoms of CPP tumors in CPA through all cases reported in the literature. In this study, Data regarding presenting symptoms of 60 adult patients (including 53 adult patients identified from the literature and our seven new patients that presented in this study) with CPP in CPA were reviewed. Symptoms related to 8th cranial nerve, lower motor, 7th, and 5th cranial nerves were the most prevalent symptoms respectively following ICP rising and cerebellar signs. The most common symptoms were related to the ICP elevation, cerebellar and auditory system involvement. The rarity of CPP tumors in CPA along with a variety of presenting symptoms makes the diagnosis of CPPs more challenging while considering this variance could be helpful in prompt diagnosis.
