Multiple cerebral hemorrhages in HTLV-I-associated myelopathy

We describe a 66-year-old woman with long-standing HTLV-I-associated myelopathy who developed multiple parenchymal hemorrhages and whose angiogram suggested cerebral vasculitis. After cyclophosphamide and glucocorticoid therapy, both her acute deficits and chronic paraparesis improved. HTLV-I may be an etiologic agent in isolated angiitis of CNS.
