Abstract
Central pontine myelinolysis (CPM) occurs in the setting of rapidly corrected hyponatremia, especially in chronically debilitated patients. Conventional CT and MR imaging findings lag the clinical manifestations of CPM. We present a case in which restricted diffusion was identified within the central pons by using MR diffusion-weighted imaging within 24 hours of onset of patient tetraplegia and before findings were conspicuous with conventional MR imaging sequences (T1, T2, and fluid-attenuated inversion recovery).
摘要
中央桥脑髓鞘溶解症（CPM）发生于快速纠正低钠血症的情况下，尤其是在慢性衰弱患者中。传统CT和磁共振成像（MR）表现滞后于CPM的临床表现。我们报告一例，在患者四肢瘫发作24小时内，在传统MR成像序列（T1、T2和液体衰减反转恢复序列）表现明显之前，通过MR扩散加权成像在脑桥中央发现了扩散受限。
