磁共振成像诊断糖尿病性肌梗死并文献复习

Magnetic resonance imaging in diagnosing diabetic myocardial infarction： case report and literature review

目的探讨糖尿病肌梗死（DMI）的发病机制、磁共振成像（MRI）表现和临床诊断。方法对经MRI和彩色超声检查，临床确诊DMI的1例患者的临床资料结合相关文献进行回顾性分析。结果DMI患者MRI示下肢受累肌肉增粗，肿胀，体积增大，信号异常增高，肌肉间隔模糊消失，皮下组织水肿。与既往文献报道相符。结论糖尿病患者突发下肢肌肉肿痛，MRI显示受累肌肉增粗、肿胀，信号异常，水肿并肌间隔模糊，筋膜下积液，即可诊断此病。

Objective To discuses the pathogenesis, magnetic resonance imaging （MRI） manifestations and clinical diagnosis of diabetic muscle infarction （ DMI ）. Method Clinical data of one patient diagnosed as DMI by MRI and color Doppler ultrasound was retrospectively analyzed combined with relative literature. Result MRI displayed that the involved muscle in the low limb was thickened and swelling, with abnormal signal; the intermuscular septa was fuzzy and disappeared, with edema of subcutaneous tissue. Consistent with previous literature reports. Conclusion DMI can diagnosed in diabetic patients with sudden limb muscle pain, showing thickened and swelling muscle with abnormal signal, edema and fuzzy intermuscular septa, and subfascial effusion in MRI.
