目的观察蜂蜇伤致横纹肌溶解的MRI表现,探讨MRI对蜂蜇伤致横纹肌溶解症的诊断价值。方法收集2008年9月2009年12月急诊科及肾内科蜂蜇伤患者4例。对其行蜇伤部位MR增强扫描,对其中1例患者行远离部位肢体扫描。总结MRI征象,评价MRI在蜂蜇伤所致横纹肌溶解临床诊治中的作用。结果蜇伤部位显示T1WI稍低,T2WI高信号影像,在T2WI加压脂影像中显示最为清晰,横纹肌损伤有局部随肌间隙扩散趋势,但远端无蜇伤肌肉受累。结论蜂蜇伤导致的横纹肌溶解可在MRI影像上得到直观反映。MRI具有良好的软组织对比度,能及时反映横纹肌受累范围及程度、治疗后恢复情况等,可为其临床诊治评估提供有利信息。
Objective To observe the MRI findings of rhabdomyolysis caused by bee stings and to explore the diagnostic value of MRI on rhabdomyolysis induced by bee stings. Methods A total of 4 patients with acute bee stings in Department of Nephrology and Nephrology, September 2008, December 2009 were collected. The stings of its stings MR enhanced scanning, of which 1 patients were remote limb scanning. MRI signs were summarized to evaluate the role of MRI in the clinical diagnosis and treatment of rhabdomyolysis caused by bee stings. Results The stings showed that T1WI was slightly lower and T2WI high signal was the most obvious in T2WI compression fat image. There was a local trend of striated muscle interspersed with interstitial diffusion in T2WI, but no stinger muscle was involved in the distal end. Conclusions Rhabdomyolysis induced by bee stings can be directly visualized on MRI images. MRI has good soft tissue contrast, can reflect the extent and extent of striated muscle involvement, post-treatment recovery, etc., which can provide favorable information for clinical diagnosis and treatment.
