Cartilaginous tumors can be subdivided into several categories according to the following three criteria: (1) Is the lesion benign or malignant? (2) Is the lesion a pure or impure cartilaginous tumor? (3) Is the epicenter of the lesion intraosseous, juxtacortical, or in the soft tissues? This article focuses on the four most common benign cartilaginous tumors, enchondroma, osteochondroma, chondroblastoma, and chondromyxoid fibroma, and on chondrosarcoma. It reviews the biologic and developmental considerations of each and discusses in depth the basic concepts in the radiologic diagnosis of cartilaginous tumors.
（1）病变是良性还是恶性？（2）病变是纯软骨肿瘤还是不纯软骨肿瘤？（3）病变的中心是位于骨内、皮质旁还是软组织内？本文重点关注四种最常见的良性软骨肿瘤，即内生软骨瘤、骨软骨瘤、软骨母细胞瘤和软骨黏液样纤维瘤，以及软骨肉瘤。本文回顾了每种肿瘤的生物学和发育方面的考量，并深入讨论了软骨肿瘤放射学诊断的基本概念。
