Reversible Posterior Leukoencephalopathy Syndrome(RPLS) -with special reference to Brain MRA-

Reversible posterior leukoencephalopathy syndrome (RPLS) is noted by a reversible syndrome of headache, altered mental function, seizures, and loss of vision associated with findings indicating predominantly posterior leukoencephalopathy on imaging studies. Reversible vasospasm and brain capillary leak syndrome are usually suggested to the pathophysiologic mechanism of RPLS. We report 6 patients with RPLS, which showed peculiar findings in the MRA.
