Myositis ossificans is a non-neoplastic benign reactive bone and cartilage matrix-producing pseudotumor that develops in skeletal muscles adjacent to the joint. The clinical and pathologic appearance of myositis ossificans varies depending on the time elapsed after heterotopic bone formation. Although its etiology is unclear, it usually occurs at the site of the injured muscle, most commonly in large muscles of the extremities, especially the quadriceps and brachialis. It rarely occurs in the paravertebral muscle of the lumbar spine.
We present the rare case of a 31-year-old Turkish man with calcifying myositis ossificans not associated with trauma, referred to our hospital with severe low back pain with restriction of low back motions. Radiological investigation suggested a sclerotic osteoblastic on the left facet joint of L4-5. To confirm the diagnosis, the patient was managed surgically by total excision of the mass, which resulted in a good functional recovery. At his 12-month follow-up examination, he was neurologically intact and no recurrence was seen.
Cases like this should be investigated well, so careful correlation of the clinical and radiologic findings with taking a biopsy is necessary to confirm diagnosis.
骨化性肌炎是一种非肿瘤性良性反应性骨和软骨基质生成的假瘤，发生于关节附近的骨骼肌。骨化性肌炎的临床和病理表现取决于异位骨形成后经过的时间。尽管其病因尚不清楚，但通常发生在受伤肌肉的部位，最常见于四肢的大肌肉，尤其是股四头肌和肱肌。它很少发生在腰椎的椎旁肌。
我们报告了一例罕见的31岁土耳其男性钙化性骨化性肌炎病例，该病例与创伤无关，因严重腰痛伴腰部活动受限转诊至我院。影像学检查提示L4-5左侧小关节有硬化性成骨细胞。为明确诊断，对患者进行了手术，完整切除肿块，术后功能恢复良好。在12个月的随访检查中，他神经功能完好，未见复发。
对于此类病例应进行充分检查，因此临床和影像学检查结果与活检结果仔细关联对于确诊是必要的。
