Choroid plexus papilloma in an infant.
A case of choroid plexus papilloma (CPP) associated with overproduction of cerebrospinal fluid (CSF) in an infant is reported. The tumor was totally resected. Histologically, it was diagnosed as CPP with several mitosis, however, there were no other features indicating malignancy. Transthyretin immunoreactivity was found in the tumor cells on CSF cytological examination as well as in surgical specimens. Though the percentage of PCNA was high (10.8%), it was not higher than other benign CPPs (mean score: 18.2%). There was no recurrence or dissemination on follow-up CT or MRI 1 year after surgery. The patient has grown normally after surgery without a shunting procedure.
