目的探讨骨血管源性肿瘤的影像学特点,旨在提高其诊断水平。方法对发生在不同部位的23例骨血管源性肿瘤的X线片、CT片和MRI片进行回顾性分析。结果19例骨血管瘤典型影像学表现根据其发生部位分为3种:椎体为栅栏状或网眼状;颅骨为放射状;长管状骨为多囊状或泡沫状。19例中术前误诊为骨纤维异常增殖症和骨巨细胞瘤各1例。4例骨血管肉瘤的影像学主要表现为溶骨性骨质破坏或骨质破坏与成骨增生混合存在。术前误诊为骨纤维异常增殖症及脊索瘤各1例和未定性2例。4例术后虽然进行放、化疗,但仍有2例在短期内发生肺及纵隔转移。结论典型骨血管瘤的影像学具有一定的特征性表现,结合临床资料,一般可做出诊断。而骨血管肉瘤的影像学表现无特征性。
Objective To investigate the imaging features of bone-derived tumors in order to improve their diagnostic level. Methods A retrospective analysis of X-ray films, CT films and MRI films of 23 cases of osteogenic tumors in different sites was performed. Results The typical imaging findings of 19 cases of hemangiomas were divided into three types according to the site of their occurrence: the vertebral body was palisade or mesh; the skull was radial; the long tubular bone was multi-cystic or foamy. 19 cases of preoperative misdiagnosis of bone fibrous dysplasia and giant cell tumor of bone in 1 case. Four cases of angiosarcoma imaging mainly osteolytic osteolytic or bone destruction and hyperplasia mixed existence. Misdiagnosed as preoperative bone dysplasia and chordoma in 1 case and 2 cases of unidentified. Although 4 patients underwent radiotherapy and chemotherapy, 2 patients still had lung and mediastinal metastasis in a short period of time. Conclusion The imaging features of typical hemangiomas have some characteristic features. Combined with clinical data, the diagnosis can be generally done. The imaging findings of osteosarcoma sarcoma no characteristic.
