骨化性肌炎的临床和MRI表现分析

The manifestation of MR imaging in myositis ossificans

目的:分析骨化性肌炎的临床和MRI表现特点,以提高其诊断和鉴别诊断的能力。方法:对16例经手术或穿刺病理证实为骨化性肌炎患者的临床和MR检查图像进行回顾性分析。结果:外伤后四肢痛性软组织肿块是其主要临床表现,T2WI上见有团块和分叶状不均匀信号、边缘有低信号带形成的软组织肿块,周围有显著的水肿带是其特征性的MRI表现。结论:骨化性肌炎临床上多有外伤史,MRI表现具有一定的特征性,提高对其MR表现的认识有助于诊断和鉴别诊断,避免不必要的手术。

Objective：To analyze the manifestation of MR imaging in myositis ossificans, and to enhance the ability in the diagnosis and differential diagnosis. Methods：The clinical data and MR imaging in 16 eases of myositis ossifieans pathologically proved were reviewed retrospectively. Results：The main clinical manifestation was painful traumatic mass in the extremities;The typical MR manifestation was a lobulated mass with surrounding lower signal zone On T2 weighted imaging, and surrounding soft tissue edema. Conclusion： The manifestation of clinical and MR Imaging in myositis ossificans have some extent characteristics. Tiffs recognition is helpful in the diagnosis and differential diagnosis of myositis ossificans, and avoiding unnecessary operation.
