Cessation of cerebral hemorrhage recurrence associated with corticosteroid treatment in a patient with cerebral amyloid angiopathy

We report the case of a 65 year old female patient with biopsy–proven cerebral amyloid angiopathy (CAA). She experienced intracerebral hemorrhages 4 times during 23 days but these serious strokes did not recur after corticosteroid therapy was started and her condition greatly improved. Since high titers of antinuclear antibodies and elevated erythrocyte sedimentation rate were found in her serum, she may have an inflammatory disorder involving amyloid–laden cerebral vessels. This is the first report showing the usefulness of corticosteroid for the treatment of CAArelated cerebral hemorrhages. Additionally, the concentrations of A β40 and Aβ42 in the CSF of this patient decreased rapidly after the use of corticosteroid, and ultimately fell far below normal values.
