A 14-year-old boy presented with upper backache and a painful swelling in the right paraspinal region for 7 days. He had no history of trauma. MRI showed a non-specific ill-defined heterogeneous lesion, which showed intense postcontrast enhancement. Ultrasonogram showed a peripheral sheet of calcification around the lesion. A CT scan showed a faint rim of calcification, which increased in thickness over weeks, confirming the diagnosis as myositis ossificans. We present our approach to the case and also review the imaging features of different stages of the disease process and their differentials.
一名14岁男孩因上背部疼痛和右椎旁区域疼痛性肿胀7天前来就诊。他没有外伤史。磁共振成像（MRI）显示一个边界不清的非特异性异质性病变，增强扫描后有明显强化。超声检查显示病变周围有一圈外周钙化。计算机断层扫描（CT）显示有一层淡淡的钙化边缘，数周内厚度增加，确诊为骨化性肌炎。我们介绍了该病例的处理方法，并回顾了疾病不同阶段的影像学特征及其鉴别诊断。
