A RARE OCCURRENCE OF REVERSIBLE CYTOTOXIC EDEMA IN REVERSIBLE POSTERIOR LEUCOENCEPHALOPATHY SYNDROME

Common imaging feature of reversible posterior leukoencephalopathy syndrome (RPLS) is with symmetric vasogenic edema involving pareitooccipital region. The predilection for posterior circulation is thought to be due to relative lack of sympathetic innervation at the level of the arterioles supplied by the vertebrobasilar system compared with the anterior circulation. However involvement of frontal , temporal lobes,deep white matter,basal ganglia, cerebellum,brain stem all have been reported to varying extent. This is a rare case report of reversible cytotoxic edema along the pyramidal tracts in a patient with RPLS.
