Severe and isolated headache associated with hypertension as unique clinical presentation of posterior reversible encephalopathy syndrome

Abstract

BackgroundPosterior reversible encephalopathy syndrome is a potentially reversible clinicoradiologic syndrome characterized by headache, mental confusion, visual disturbances and seizures associated with posterior cerebral lesions on radiological imaging. Prompt treatment of this condition is mandatory to avoid severe irreversible complications.Case presentationWe report a 9-year-old boy with arterial hypertension and headache as unique clinical presentation of posterior reversible encephalopathy syndrome.ConclusionsSevere and isolated headache associated with arterial hypertension can be the unique clinical presentation of posterior reversible encephalopathy syndrome. This syndrome must be considered even in absence of all typical symptoms to prevent the progression of a potentially life threatening condition.

Posterior reversible leukoencephalopathy syndrome associated with acute postinfectious glomerulonephritis: systematic review

“…2 . For the final analysis, we retained 47 scientific reports [ 4 , 5 , 14 – 58 ] detailing 52 original cases published since 1993: 22 from Asia (Turkey, n = 8; India, n = 7; Japan, n = 3; Pakistan, n = 1; Saudi Arabia, n = 1; Sri Lanka, n = 1, Taiwan, n = 1), nine from Europe (Germany, n = 2; Italy, n = 2; Belgium, n = 1; Greece, n = 1; Netherlands, n = 1; Spain, n = 1; Switzerland, n = 1), eight from North America (USA, n = 7; Canada, n = 1), six from South America (Argentina, n = 2; Brazil, n = 1; Colombia, n = 1; Trinidad, n = 1; Uruguay, n = 1), and two from Africa (Morocco, n = 1; Tunisia, n = 1). Thirty-eight articles were published in English, five in Spanish, two in French, one in Dutch, and one in German.…”

“…Stimulated by our past experience [4,5], we report here the first systematic literature review on PRES in postinfectious (poststreptococcal) glomerulonephritis, the prototypical and most widely known acute glomerulonephritis syndrome [6,7]. The objectives were to document features, associated factors, neuroimaging data, and clinical course.…”

Transient Global Amnesia with Reversible White Matter Lesions: A Variant of Posterior Reversible Encephalopathy Syndrome?

“…Although PRES usually presents with seizures, altered mental status, headache, and visual disturbances, it can present in various ways [ 4 ]. Even a case of isolated headache has been reported [ 10 ]. Although amnesia has not been described as a common symptom in PRES, two cases of PRES that developed amnesia without altered mental status have been reported [ 11 , 12 ].…”
