A 53-year-old man presented with optic neuritis, followed within 10 weeks by a subacute progression of weakness, ataxia, and multiple cranial nerve palsies. Cranial magnetic resonance imaging demonstrated multiple T2-hyperintense lesions extending from the ponto-medullary junction to the thalamus and internal capsule. Cerebrospinal fluid analysis showed lymphocytic pleocytosis with elevated protein content. A brain biopsy revealed inflammatory changes. After a month long period of inexorable worsening, the patient was treated with intravenous immunoglobulins (2 g/kg). He responded to treatment, and recovered over the subsequent 3 months. The patient's response to treatment suggests that intravenous immunoglobulins should be considered in patients with inflammatory brain disorders.
