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

Background: Posterior 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. Conclusions: Severe 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 symtom to prevent the progression of a potentially life threatening condition.
