Benign Chondroid Matrix Bone Tumors

Chapter 54 discusses benign chondroid matrix bone tumors, which are the most common benign primary bone tumors. They include osteochondroma, enchondroma, periosteal chondroma, chondroblastoma, and chondromyxoid fibroma. Osteochondromas are bony exostoses that are the most common benign bone tumor in all ages. Most of these neoplasms have characteristic imaging features that can allow accurate diagnosis. Radiography is the mainstay modality of choice for initial workup. MRI and CT can provide increased diagnostic confidence and accuracy, and have become essential tools that guide clinical management of the benign cartilage bone tumors. Treatment can be surgical, including bone grafting, or with radiofrequency ablation.
