INTRODUCTION: In 1996, Hinchey et al described a clinico-radiological picture they called posterior reversible @entity62 syndrome (PRLS), which is characterized by @entity227 , @entity410 , altered mental states and changes in the subcortical white matter of the temporoparietooccipital lobes that are shown up in the neuroimages. These clinical manifestations are associated with @entity101 . Later, other triggering elements, such as cytostatic drugs, were described without being linked to @entity101 . Other authors have suggested the name of posterior reversible @entity75 , since magnetic resonance imaging (MRI) reveals a high percentage of cortical compromise. CASE REPORTS: We present three cases of posterior reversible @entity75 with different origins. Two of the cases involved females, one of whom was a 19-year-old @entity101 with @entity8 and the other was a 33-year-old with @entity3036 . The third case was an 11-year-old male @entity1 with post streptococcal @entity631 and @entity101 . The most relevant signs and symptoms included @entity410 , @entity227 , @entity101 and @entity13317 . MR played a decisive role in diagnosis and it revealed an alteration of the signal in the supra and infratentorial white matter of the cortex and the subcortex, which was predominant in the posterior areas of the @entity75 . The three cases presented a significant radiological and clinical improvement in a short time. CONCLUSION: Failure of the self regulation of cerebral vascular circulation, with development of @entity4 , is the most widely accepted hypothesis to explain the pathophysiological mechanism at work in this entity.
