Sir,

We read an interesting case report by Nayak published in April 2014 issue of this esteemed journal. [1] Of course, the posterior reversible encephalopathy syndrome (PRES) was recognized in 1996, [2] but with the advent of modern imaging specially magnetic resonance imaging (MRI) the disease is not under-recognized more so in pregnant females in peripartum period. In a peripartum lady with the signs and symptoms of headache, nausea, vomiting, seizures, visual disturbances, altered sensorium, with or without focal neurological deficits, with rapidly progressive blood pressure, an expert clinicians will certainly think of PRES or will be guided by referral neurologist and goes for MRI straight forward. Rarely, there could be spinal cord involvement also in PRES.

Among the important causes of PRES besides eclampsia, the other ones are renal disease, hypertensive encephalopathy, systemic lupus erythematosus, sepsis, thrombotic thrombocytopenic purpura, endocrinopathies, cytotoxic/immunosuppressive drug therapy, e.g., cyclosporin, tacromilus, complication of reversible cerebral vasoconstriction syndrome.

It has also been argued that this syndrome may be a neuroradiological expression of various metabolic disorders, which affect the central nervous system including seizures. We in our day today practice frequently encounter such patients and if deserve than also get them documented. [3],[4] There is also a recent case report of PRES with rodenticide poisoning. [5]

The first-line drug of choice for such patients is the beta blocker labetalol and calcium channel blocker given intravenously in a critical care setting with close hemodynamic monitoring. Sodium nitroprusside is not considered because of its adverse effect on cerebral blood flow. The aim of this correspondence is to make awareness that PRES is not an under recognized entity for the sense that misdiagnosis of an under-recognized disease is excusable up to some extent, which is not so in well recognized disease entity.
