Multifocal meningiomas in a patient with a constitutional ring chromosome 22.


We report a patient with a constitutional ring chromosome 22, in whom multifocal meningiomas were confirmed at necropsy, and discuss the relationship between the constitutional chromosome change and tumourigenesis of meningiomas in this patient.
