Acute Symptomatic Hyponatremia After Computed Tomography Renal Protocol

J Comput Assist Tomogr. 2017 Jan;41(1):65-66. doi: 10.1097/RCT.0000000000000487.

Abstract

Computed tomography (CT) is a widely used imaging modality. Although hyponatremia after CT imaging is rare, its effects can be devastating. Hyperosmolar radiocontrast acts as effective osmoles and causes fluid migration from intracellular into extracellular compartment. Dilutional hyponatremia will ensue if translocation of fluid is in excess of diuresis. This case report detailed an unusual case of acute symptomatic hyponatremia after CT renal protocol and the treatments given after its recognition.
