| 摘 要：［目的］ 分析骨化性肌炎的MRI表现，以提高对该病的影像诊断及鉴别诊断水平。［方法］ 对10例经病理证实的骨化性肌炎的MRI表现进行分析，并复习相关文献。［结果］ 10例骨化性肌炎为早期或中期病变。病灶分布在大腿7例，腹股沟区1例，腹壁1例，上臂1例。骨化性肌炎T1WI呈等或者稍低信号，T2WI呈高信号，4例伴有低信号区。4例增强扫描病灶明显强化，短T2信号区可见强化。1例累及骨髓。［结论］骨化性肌炎MRI表现复杂，但好发于股部肌肉、T2WI高信号为主，伴有短T2信号区的强化时提示骨化性肌炎的可能。 |

| Abstract：［Purpose］ To investigate MRI findings of myositis ossificans in the early and middle stage.［Methods］ MRI imaging of 10 cases with myositis ossificans pathologically proved were retrospectively analyzed，and the literatures were reviewed. ［Results］ Ten cases were in the early or middle stages. Of the 10 cases，7 cases occurred in the thigh，1 in the inguinal region，1 in the abdominal wall and 1 in the upper arm，respectively. Lesions showed equal or slightly low signal on T1WI and high signal on T2WI. In 4 cases low signal zone could be seen on T2WI. After injection of contrast agent lesions enhanced obviously in 4 cases，and the region with short T2 signal could be enhanced. The bone marrow was involved in 1 case. ［Conclusion］ MRI reveals various characteristics of myositis ossificans.It may be diagnosed as myositis ossificans if the lesion of hyperintense on T2W images occurred in the thigh. Especially the area of short T2 in the mass could be enhanced. |
