原发骨脉管性肿瘤(附三例报告及文献复习)

Primary vascular tumor of bone: report of 3 cases and review of the literature

目的 提高对骨脉管性肿瘤的影像学认识。方法 报告 3例经病理证实的罕见骨脉管性肿瘤的X线平片和CT所见 ,并作文献复习。结果 本组 3例罕见骨脉管性肿瘤 ,1例为多发性血管内皮细胞瘤 ,2例为恶性血管外皮细胞瘤 ,X线表现均以溶骨性破坏为特征。结论 原发骨脉管性肿瘤在临床和X线表现上都缺乏特异性 。

Objective To enhance the understanding of vascular tumor of bone on imaging findings. Methods Three cases of rare vascular tumor of bone confirmed pathologically were reported by X ray plain film and CT findings, and the literature was reviewed. Results Three cases of rare vascular tumor of bone (multiple hemangioendothelioma in 1 case, malignant hemangiopericytoma in 2 cases) had the characteristic imaging appearance as osteolytic destruction. Conclusion There was less specific clinical and imaging features of vascular tumor of bone, the define diagnosis should still depend on histology.
