　　【摘要】 糖尿病肌梗塞(又称“糖尿病肌坏死”)是一种少见的糖尿病微血管并发症，常被误诊为“蜂窝组织炎”，且在糖尿病患者中该诊断有重要作用。发生糖尿病肌梗塞的患者预后差，死亡率高，临床医师应提高对该病的认识和管理。本文报道1例经双下肢核子共振成像(MRI)及肌肉活检诊断为糖尿病肌梗塞患者，经抗凝等对症治疗后,患者症状改善。

　　【Abstract】 Diabetic muscle infarction (also known as ‘diabetic myonecrosis’) was a rare diabetic microvascular complication and was often misdiagnosed as cellulitis.The accurate diagnosis was important for these diabetic patients. There was poor prognosis and high mortality in patients with diabetic muscle infarction, so clinicians should raise awareness and management of this disease. Here, we presented a case of patient with diabetic muscle infarction in lower limb by MRI and muscle biopsy diagnosis. After treatment with anticoagulation, the symptoms were improved.
