Multiple meningiomas in different neuraxial compartments. Report of two cases.

Multiple meningiomas in different neuraxial compartments are quite rare. The authors report two new cases of association between cranial and spinal meningiomas, one of them in a patient operated upon for multiple intracranial meningiomas. The first case was a 60-year-old woman with progressive paraparesis who had been operated on 13 years earlier for multiple intracranial meningiomas. A myelo-CT scan showed a block of contrast medium at T1-T2; the lesion was removed via a standard laminectomy. The second patient was a 76-year-old woman with a 6-month history of spastic paraparesis. MRI detected an extramedullary intradural lesion at T6-T7. A cerebral MRI, performed because of the onset of seizures, showed a right parietal lesion. Removal of the thoracic lesion was followed, 6 months later, by removal of the cerebral one. Both patients presented a progressive improvement of the paraparesis and returned to normal daily activities.
