Synchronous supratentorial and infratentorial choroid plexus papilloma: case report and review of the literature

Abstract Background Choroid plexus papilloma (CPP) occurs in children as a lesion usually in the lateral ventricle. It is an uncommon tumour in adults and occurs mostly in the 4th ventricle. Other locations in children and adults are relatively less common. Multiple choroid plexus papillomas (MCPPs) as well as ectopic choroid plexus papillomas are rare entities. Case report Hereby, we present a unique case of a 29-year-old male with two synchronous CPPs, one in the 4th ventricle and another lesion in the left temporal polar region. He was successfully treated with staged surgery and had a good outcome. Conclusion Staged surgery for resection of both or all the lesions, starting from lesion causing obstructive hydrocephalus or the largest lesion to the smaller ones, is a safe treatment option.
