Abstract
Attention is directed to the diagnosis of acute hemorrhagic leukoencephalitis and the possibility of its clinical recognition is discussed. Three case histories, two diagnosed at autopsy and one clinically, are presented. The latter was treated with very generous doses of steroids and recovered spectacularly. On omission of steroids, a mild, temporary clinical recurrence occurred. Clinical, clinicopathologic, and pathologic aspects of the disease are discussed, and etiologic factors mentioned. Some thoughts on the relationship of this disease to experimental allergic encephalomyelitis are mentioned. Differential diagnosis is considered and the use of biopsy for confirmation of diagnosis especially from herpes encephalitis considered. A plea is made for the trial of treatment with large doses of steroids.
