[Benign choroid plexus papilloma. 2 local recurrences and intraventricular seeding]

Abstract

The authors report a case of choroid plexus papilloma developped in the fourth ventricle. After complete surgical resection, two local recurrences of the tumor occurred, and required new surgical procedures. Eight years after the first operation, a papilloma of the right lateral ventricle was resected. The histological examination showed benign choroid plexus papilloma after each operation. Recurrence and seeding of benign choroid plexus papillomas are infrequent in the literature. For this reason, a long-term follow-up, by clinical examination and CT scan, is necessary for those patients.
