侵袭性骨母细胞瘤影像学分析

Imaging Diagnosis of Aggressive Osteoblastoma

目的探讨侵袭性骨母细胞瘤的影像表现及提高其影像诊断水平。资料与方法回顾性分析9例经病理证实的侵袭性骨母细胞瘤患者的X线、CT、MRI表现。8例行X线平片检查,4例行CT检查,6例行MRI检查。结果 9例侵袭性骨母细胞瘤中,6例表现为斑片状、虫蚀样的溶骨性骨质破坏,3例呈膨胀性骨质破坏,3例可见短小液-液平面,3例可见斑点状及絮状钙化影,1例可见硬化边,2例可见葱皮状骨膜反应,9例均可见明显软组织肿块。结论综合分析侵袭性骨母细胞瘤影像学资料能够提高对其诊断的准确性。

Objective To explore the imaging findings of aggressive osteoblastoma and to improve diagnosis.Materials and Methods Plain film,CT and MRI findings of 9 cases with pathologically approved aggressive osteoblastoma were retrospectively analyzed.Results Among the 9 cases of aggressive osteoblastoma,6 cases presented as moth-eaten-like or rotten-wood-like cortical destruction,3 cases appeared expansive destruction,3 cases showed the short and small liquid-liquid level on MRI,3 cases had mottled and fluffy calcification,1 case had sclerotic and spiculae periosteal reaction,and large soft-tissue masses can be seen in all of the cases.Conclusion Combining with imaging information of aggressive osteoblastoma can improve the diagnosing accuracy.
