A case of demyelinating encephalomyelitis with some resemblance to collagen disease.
A woman, aged 26 years, who died of progressively worsening demyelinating encephalomyelitis in the course of 4 years is reported. The neuropathological findings included large subcortical softenings in the cerebral hemispheres, tiny perivenous demyelinated foci in their neighborhood and scattered in the white matter. There was an acute vasculitis with fibrinoid exudation in the affected as well as unaffected areas. Focal perivenous mononuclear cell infiltrations are conspicuous in the white matter. The laboratory and postmortem examinations suggested a collagen disease like SLE. The abnormalities included marked increase of serum gamma-globulin, especially of IgG, and elevation of CRP, RA, and ANA titer, moderate thickening of the basement membranes of the renal glomeruli, onion skin-like periarteriolar fibrosis in the spleen, fibrous pericarditis and periadventitial fibrosis of myocardial arteries. Bilateral degeneration of the spinal posterior columns and dorsal roots was also observed. A probable relationship of the modified features in this example of demyelinating encephalomyelitis with abnormal immune mechanisms in the background is discussed.
