Combined occurrence of primary cerebral lymphoma and meningioma.

A unique combination of primary cerebral lymphoma and meningioma was encountered in a 38-year-old woman who recently presented clinically with headache and papilledema. The both tumors were identified by CT scan and diagnosed histopathologically after the surgery. The association of a highly malignant primary cerebral lymphoma and a slowly growing meningioma is extremely rare. The possibility of an unknown underlying pathologic mechanism predisposing to multiple tumors should be considered.
