Brain involvement in scleroderma: two autopsy cases
1Service de Médecine Vasculaire and the Centre Claude Bernard de Recherche sur les Maladies Vasculaires Périphériques, Hôpital Broussais, Paris, France.
Background:
Neuropathological data are very scarce in systemic sclerosis and fail to demonstrate primary changes in the brains of such patients.
Case Descriptions:
A 41-year-old woman with CREST syndrome developed signs of dementia after an episode of severe dehydration and died two months later of septic shock. A 63-year-old woman with CREST syndrome and a history of two unexplained transient ischemic attacks had had balance disorders since age 62. She died of severe pulmonary hypertension. In both cases, the autopsy showed extensive wall calcification of small arteries and arterioles in the brain, primarily in the basal ganglia, and also in the frontal lobes and the cerebellar area in the second case. No known cause of cerebrovascular calcification was found in either patient.
Conclusion:
The neuropathological findings in these two patients suggest that systemic sclerosis may induce primary vascular changes in the brain, of which calcification may be a marker.
