Cerebrovascular lesions and livedo reticularis (Sneddon's syndrome)--a progressive cerebrovascular disorder?
Four cases are described in which livedo reticularis was associated with repeated cerebrovascular accidents, which eventually resulted in severe disability in two cases. Patients with severe disability had a history of many years, whereas two patients with little or moderate residual disability had a follow-up of 3 years each. CT scan revealed multifocal cerebral infarctions and cortical atrophy in all cases. Repeated cerebral angiograms, done in three cases, showed no signs of a vascular disease. There were no parameters that pointed to active immunological or inflammatory disorder. Neither clinical evidence of heart or large vessel disease was found. Observations suggest that a so-far unknown progressive cerebral vessel disease associated with livedo is the cause of a steady increase in multiple small cerebral infarctions. Because of the progressive character of the disease the search for effective therapy is needed.
