摘要
目的:探讨骨膜骨肉瘤的影像及组织病理学特点。材料和方法:收集7例经病理证实的骨膜骨肉瘤,结合有关文献对其影像及组织病理学表现进行分析和总结。结果:骨膜骨肉瘤好发于胫骨,影像学上表现为发生在长骨的骨干或相当于干骺部位置的骨表面肿块,内见局灶性骨化或/和钙化,边缘可见骨膜反应,肿瘤下骨皮质可受侵,但不侵犯骨髓腔。病理上类似于软骨母细胞型的骨肉瘤,中度异型性。结论:骨膜骨肉瘤在影像和组织病理学上都有一定特点,影像与病理相结合对做出正确诊断是很重要的。
Purpose: To investigate the radiological and histopathological features of periosteal osteosarcoma. Materials and Methods: Seven cases of periosteal osteosarcoma, pathologically proven, were analyzed for the clinical, imaging and histological findings in combination with relevant literature. Results: Periosteal osteosarcoma was frequently found on tibia. On imaging, periosteal osteosarcoma appeared as a partially mineralized mass on the cortical surface of a long bone in the portion of the diaphysis or metaphysis. By the margin of tumor, periosteal reaction was revealed, and erosion of the underlying cortex was observed, while the medullary cavity remained intact. Histologically, periosteal osteosarcoma is a moderately differentiated chondroblastic osteosarcoma. Conclusion: Combination of imaging and pathological examinations is important for diagnosis of the periosteal osteosarcoma.
