目的回顾性分析15例长骨和扁 骨骨内血管瘤影像学表现特点。方法 患 者进行X线、CT和MRI检查，评估疾病位 置、大小、边缘、内部骨化或钙化和肿瘤 向外扩张情况。结果 X线发现分叶状溶骨 性破坏伴有硬化缘8例，增粗骨小梁4例， 基质骨化1例，大块状钙化1例。MRI 显示 髓内血管瘤呈软组织肿块样改变；CT显示 分叶状溶骨性破坏，大部分增粗骨小梁， 基质骨化和骨皮质改变。结论 长骨和扁 骨内血管瘤影像学表现具有一定的特征 性，但不具有特异性，应该与软骨类和膨 胀溶骨性破坏性肿瘤相鉴别，最终需要病 理检查确诊。

Objective To retrospectively study the imaging findings of 15 patients with hemangioma of Long bone and flat bones. Methods X-ray, magnetic resonance imaging (MRI), and computed tomography were performed. X-ray, MRI and CT studies were evaluated for lesion location, size, margin, internal matrix mineralization, and extraosseous extension. Results Radiographs identified the lobular osteolytic intramedullary lesions with sclerotic margins (8 cases) and coarse linear trabeculation (4 cases), matrix ossification (1 case), a heavily calcified lesion (1 case). MRI also identified the soft tissue mass in the case of the subperiosteal hemangioma. The CT scan demonstrated the lobular osteolytic lesions, the prominent trabeculation and matrix mineralization and evaluated the cortex. Conclusion To reported series of imaging features of intraosseous hemangiomas of Long bone and flat bones of hemangioma. The lesion should be differentiated from other chondral or expansile lytic tumors. The final diagnosis can only be confirmed by histopathology.
