Severe neonatal hypernatraemia is a life-threatening electrolyte disorder b ecause of its neurological complications. These are brain oedema, intracran ial haemorrhage, haemorrhagic infarcts and thromboses. There are few report s concerning the radiological findings in the central nervous system in sev ere neonatal hypernatraemia. Cranial MRI findings in hypernatraemia have be en reported in an older child, but have not been described in newborn infan ts. We report the cranial MRI findings in a newborn infant with acute renal failure and severe hypernatraemia.
