糖尿病性肌梗死的MRI表现并文献复习

MR Features of Diabetic Muscle Infarction: One Case Report and Literature Review

目的探讨糖尿病肌梗塞的MRI表现和病理学基础,以提高对本病的认识。方法对1例确诊糖尿病肌病的患者的MRI表现及临床特点进行回顾性分析,并对相关文献进行复习。结果 MRI平扫质子密度加权压脂后示受累肌肉呈明显高信号,周围脂肪间隙模糊,并可见邻近筋膜下积液,增强后呈弥漫性明显强化。结论 DMI是一种继发于糖尿病Ⅰ型或是糖尿病Ⅱ型的少见并发症,MRI是此疾病诊断和随访的首选影像检查手段,MRI的影像表现结合临床特点可以使多数病例得到确诊,从而避免活检或是手术的有创不良后果。

Objective To investigate the MRI findings and pathogenesis of diabetic muscle infarction. Methods The MRI manifestations and clinical characteristics of one patients with diabetic muscle infarction were retrospectively analyzed combined with relative literatures. Results Multiple thigh and calf muscles was thickened and swelling, PDWI demonstrates an increased signal, the surrounding adipose space was blurred, and adjacent subfascial effusions were seen. Conclusion DMI is a rare complication secondary to type Ⅰ or type Ⅱ of diabetes. MRI is common for diagnosis and follow-up of the disease. The imaging features of MRI can make the diagnosis of most cases, thus avoiding the adverse consequences of biopsy or operation.
