Abstract：
Osteochondromas account for 20%-50% of all benign bone lesions. These tumors may present as solitary non-hereditary lesions, which are the most common presentation, or as multiple tumors associated with hereditary conditions. Plain radiography is the imaging method of choice and demonstrates the typical cortical and medullary continuity of the tumor with the underlying bone. Magnetic resonance imaging is often performed to evaluate cartilage cap thickness, which correlates with malignant transformation. Other local complications include compression of adjacent neurovascular bundles, muscles, and tendons, bursitis, tendon tears, stalk fracture, and angular or rotational long bone deformities. Although the imaging features of osteochondromas are largely known, only a few papers in the literature have focused on their main complications and image-based follow-up. This paper aimed to illustrate the main complications of osteochondromas, suggest an image-based algorithm for management and follow-up and discuss differential diagnosis.
摘要：
骨软骨瘤占所有良性骨病变的20％-50％。这些肿瘤可能表现为孤立的非遗传性病变，这是最常见的演讲，或与遗传性疾病相关的多发性肿瘤。X线平片是首选的成像方法，可证明肿瘤与下方骨骼的典型皮质和髓质连续性。通常进行磁共振成像以评估软骨帽厚度，这与恶性转化有关。其他局部并发症包括压迫邻近的神经血管束，肌肉,和肌腱，滑囊炎,肌腱撕裂，茎断裂,和角状或旋转的长骨畸形。尽管骨软骨瘤的影像学特征已广为人知，文献中只有少数论文关注其主要并发症和基于图像的随访.本文旨在阐述骨软骨瘤的主要并发症,建议一种基于图像的管理和随访算法，并讨论鉴别诊断。
