RESUMO
A 21-month-old boy came to our attention because of pneumonia. His weight increased before presentation, and his blood test results showed hyponatremia (116 mEq/L), low plasma osmolarity (241 mOsm/L), and high urine osmolarity (435 mOsm/L). He was treated with 0.9% sodium chloride solution and intravenous furosemide, and sodium levels rose up to 135 mEq/L in 36 hours. No standard treatment is available for severe hyponatremia in children. The use of vaptans in pediatric patients is described in literature, but it lacks evidence about safety and effectiveness. We suggest that furosemide administration plus salt replacement is effective in restoring normal values of plasma sodium concentration in severe euvolemic and hypervolemic hyponatremia.

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 PRESENTATION: We 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 symptoms to prevent the progression of a potentially life threatening condition.
