Abstract

The neuroimaging findings in an infant with hypernatremic dehydration are presented. Brain parenchymal haemorrhage and extensive multiple infarcts were present in the acute stage. Follow-up CT showed bilateral, symmetrical changes presumed to indicate extrapontine myelinolysis in the thalamus and globus pallidus. MRI confirmed sparing of the pons. Only three previous cases of neuroimaging abnormalities due to hypernatraemia have been described in the radiological literature.

摘要

本文报道了一名患有高钠血症脱水婴儿的神经影像学检查结果。急性期可见脑实质出血和广泛的多发性梗死。随访CT显示双侧对称性改变，推测为丘脑和苍白球的脑桥外髓鞘溶解。MRI证实脑桥未受累。放射学文献中仅描述了3例因高钠血症导致神经影像学异常的病例。
