MR Imaging of Brain in Maple Syrup Urine Disease: A Case Report

楓糖漿尿症在磁振造影之表現:病例報告

摘要


楓糖漿尿症是一種隱性正染色體代謝失調的病變,發生在新生兒因缺乏某種分解胺基酸之酵素所致的疾病。我們報告一例新生兒罹患此病,由於磁振造影DWI影像比傳統T2W影像對偵測腦水腫之範圍更具靈敏性,該患者得以早期診斷與治療且預後良好。

並列摘要


Maple syrup urine disease (MSUD) is an autosomal recessive metabolic disorder caused by an inborn failure to catabolize branched-chain amino acids. We report a case of a new born boy with MSUD. The diffusion-weighted MR imaging is more sensitive than T2-weighted imaging in showing extent of brain edema. Early diagnosis and treatment of this baby achieve a good outcome.
