Localized areas of active myositis ossificans, occurring without a clear history of antecedent trauma, have been referred to as a "pseudo-malignant osseous tumor of soft tissue." This lesion may be mistaken both roentgenographically and pathologically for a malignancy. The roentgenographic signs which favor a diagnosis of non-neoplastic heterotopic bone formation include a lucent zone between the lesion and the adjacent bone, an intact underlying cortex, diaphyseal location, dense calcification in the periphery, and loss of volume on serial films.
局限性活跃性骨化性肌炎，在无明确既往创伤史的情况下发生，被称为“软组织假性恶性骨肿瘤”。该病变在放射学和病理学上都可能被误诊为恶性肿瘤。支持非肿瘤性异位骨形成诊断的放射学征象包括病变与相邻骨骼之间的透亮区、下方皮质完整、骨干位置、周边致密钙化以及系列X线片上体积缩小。
