中文摘要 | 本文報告一例快速修正低血中鈉濃度導致橋腦中及橋腦外髓鞘質變性。病人右腳骨折,接受手術治療後發生低血中鈉濃度,在經由快速靜脈注射生理鹽水後,四天內將低血中鈉濃度修正回正常數值。但四天後,病人發生吞嚥困難、語言不清、四肢無力、面無表情、坐立不安等情形。核磁共振顯示橋腦及基底核在T2比重影像中有高訊號病兆。透過支持性療法,病人症狀已完全恢復,連續的 MRI 結果顯示橋腦中及橋腦外的變化完全消失。 |
英文摘要 | We report on a patient who developed central pontine myelinolysis and extrapontine myelinolysis after rapid correction of hyponatremia. He suffered open leg fracture, received operative room internal fixation, and followed by occurrence of hyponatremia. The hyponatremia was reestablished to normal levels by rapid infusion of normal saline solution over four days. Following this, he developed dysphagia, dysarthria, apathy, restlessness, and weakness in his imbs. An MRI showed symmetrical, hyperintense lesion in the pons and bilateral symmetric hyperintense lesions in the basal ganglia on T2-weighted images. After supportive treatment, the patient fully recovered without disability. Serial MRI showed complete resolution of the initial pontine and extrapontine changes. |
