Extraskeletal osteosarcoma is an uncommon and high-grade soft tissue malignancy. The incidence is even lower when the lung and pulmonary artery are the primary site. The purpose of this report is to present the radiological features of this neoplasm in a 52-year-old man. In our case, contrast-enhanced CT and 3D-CT reconstruction clearly showed the primary lesion and its invasion into surrounding tissues. Although wide local excision of the primary tumor is the treatment of choice, local recurrence and metastasis rates remain high, and this progression can be clearly shown on CT and SPECT/CT examinations.
骨外骨肉瘤是一种罕见的高级别软组织恶性肿瘤。当肺和肺动脉为原发部位时，其发病率更低。本报告的目的是呈现一名52岁男性患者中该肿瘤的影像学特征。在我们的病例中，增强CT和三维CT重建清晰显示了原发病变及其对周围组织的侵犯。尽管广泛局部切除原发肿瘤是首选治疗方法，但局部复发和转移率仍然很高，并且这种进展在CT和SPECT/CT检查中能够清晰显示。
