Late-onset tumefactive multiple sclerosis.
ABSTRACT A patient with tumefactive multiple sclerosis (MS) initially presented at the age of 87 years; the revised diagnostic criteria from the International Panel on MS (2001) were fulfilled. Late-onset MS and tumefactive demyelinating lesions are discussed. This case suggests that MS can occur at any age. MS should be borne in mind for differential diagnosis if a brain tumor-like lesion with little mass effect and edema is found in an elderly patient.

ABSTRACT: When multiple sclerosis (MS) presents late in life (after the age of 50), it frequently gives diagnostic difficulty. In a large MS clinic population (N = 838), 9.4% of the patients had late onset of MS. Slow deterioration of motor function characterized the initial symptoms and subsequent course of this group of older patients. Progression of disability was more rapid than in younger patients. Evoked response studies and CSF electrophoresis were of high diagnostic yield in the older patient group. Reasons for the differing clinical features in the late-onset patients are discussed. We suggest that the age-of-onset criterion for MS be raised to 60 in adequately investigated cases.Neurology 01/1984; 33(12):1537-44. · 8.30 Impact Factor

ABSTRACT: We present a case of tumoral multiple sclerosis in a 66-year-old male and emphasize two clinical features: (1) Multiple well-demarcated massive enhanced lesions except for the central area, which was accompanied with severe perifocal edema, occurred within the cerebral hemispheres and should be strongly considered in the diagnosis of mass lesions. The patient underwent partial removal of the mass lesion. The initial histopathological diagnosis of the surgical specimen was astrocytoma grade II. (2) Multiple lesions disappeared completely for one and half months after starting medication using steroid. The reexamination of the surgical specimen was compatible with that of multiple sclerosis. Again, half a month after remission, multiple enhanced lesions without perifocal edema developed in the cerebral and cerebellar hemisphere. The difficulty of the initial diagnosis of multiple sclerosis with severe perifocal edema was discussed, based on our experience.No shinkei geka.
