Clinical and laboratory findings in patients with multiple meningiomas

A series of eight patients with multiple meningiomas is presented. Up to 14 meningiomas were diagnosed in one patient. The clinical and laboratory findings suggest that multiple meningiomas do not constitute a disease entity of their own featuring disease-specific clinical or laboratory findings. In our series we find a female predominance with seven female and one male patient. The histological findings were mixed, even within the individual cases. There are no consistent patterns of steroid receptor levels or chromosomal aberrations in the more recent cases in which these parameters could be investigated.
