Background:
Multiple choroid plexus papillomas (CPPs) are rare. Usually, they correspond to villous hypertrophy or metastasis occurring during cerebrospinal dissemination. Multiple CPPs have rarely been reported as synchronous tumors.
Case Report:
Three synchronous CPPs were resected in a 59-year-old female 6 years after their first imaging description. Pathology showed mucus-producing CPP in all 3, 1 of the 3 presenting some signs of atypia. No p53 or hSNF5/INI1 mutation, or signs of polyoma viruses infection were found.
Conclusion:
Although no clear cause for the multifocality was found, the simultaneous presence of the three tumors and their benign histology suggest that they were synchronous and not metastatic. The issue of differentiating synchronous CPPs from metastatic CPP is discussed.
