Subclinical Venous Sinus Thrombosis Secondary to Hypernatraemic Dehydration

Abstract

An 8-day-old infant was admitted to a paediatric intensive care unit with severe hypernatraemic dehydration. An MRI brain was performed which revealed extensive venous sinus thromboses. This is a recognised but rare complication of hypernatraemic dehydration and the importance of early detection and intervention of this condition is again highlighted.This is the first case report of venous sinus thrombosis secondary to hypernatraemic dehydration in a patient with no clinical neurological signs. We postulate that there may be a cohort of infants with subclinical cerebral venous thrombosis secondary to hypernatraemic dehydration.
