Four cases of acute rhabdomyolysis are presented and the correlation between clinicopathological and MR findings is discussed.
The cases include carnitine palmitoyltransferase I deficiency presenting as compartment syndrome, acute polymyositis, acute myositis associated with Epstein-Barr virus infection, and glycyrrhizin- and diuretic-induced hypokalemic myopathy.
The T2-weighted MR images revealed high intensity lesions in the affected muscle groups. The lesions seen on MR correlated precisely with the symptoms and neurological deficits of the patients. Repeat MR studies showed that the high intensity lesions seen on T2-weighted MR images resolved in parallel with the clinical course.
This reversibility of the MR findings suggests that the high intensity lesions do not reflect permanent myopathic changes, but probably represent transient edema in the acute phase of rhabdomyolysis.
报告4例急性横纹肌溶解症病例，并探讨临床病理与磁共振成像（MR）表现之间的相关性。
病例包括表现为骨筋膜室综合征的肉碱棕榈酰转移酶I缺乏症、急性多发性肌炎、与EB病毒感染相关的急性肌炎以及甘草酸和利尿剂诱发的低钾性肌病。
T2加权MR图像显示受累肌群出现高强度病变。MR所见病变与患者的症状和神经功能缺损精确相关。重复MR检查显示，T2加权MR图像上的高强度病变与临床病程同步消退。
MR表现的这种可逆性表明，高强度病变并不反映永久性肌病改变，而可能代表横纹肌溶解急性期的短暂水肿。
