Reversible cerebral vasoconstriction syndrome (RCVS) is an increasingly recognized acute cerebrovascular condition that may produce myriad transient and sustained neurologic deficits as well as a host of radiologic features. We report the case of a woman with RCVS and a severe clinical syndrome with bilateral basal ganglia hemorrhages, cerebral infarctions, and marked vascular abnormalities. The patient made a near complete clinical recovery, representing an extreme and illustrative form of RCVS.
