Neurological complications of myeloma are multiple and various. Cranial and intracranial locations have been rarely reported. They can be classified into three clinical groups: (1) cranial nerve palsies secondary to single or multiple lesions in the base of the skull, (2) intraorbital tumors, (3) intracranial tumors, either cranial myeloma extending intracranially or pure intracranial tumor (dural and/or cerebral). In our case, macroscopic and microscopic examination of the brain showed dural and cerebral involvement, confirmed by immunohistochemical studies. The radiological features are discussed (CT scan, MRI, angiography). To our knowledge, a single report of intracranial plasmacytoma documented by MRI has been reported in the literature.
