Radiographic findings of 15 untreated chondrosarcomas of the cranial and facial bones were reviewed. These tumors have a propensity to occur in the wall of a maxillary sinus, at the junction of sphenoid and ethmoid sinuses and vomer, and at the undersurface of the sphenoid bone. Because of its slow-growing nature, chondrosarcomas tend to be large, multilobulated, and sharply demarcated when detected. Frequent bone changes are a combination of erosion and destruction, with sharp transitional zones and absent periosteal reaction. Tumor matrix calcifications, not necessarily chondroid, are almost always present. Both CT and MR may be necessary for thorough evaluation of tumor extent.
回顾了15例未经治疗的颅面骨软骨肉瘤的影像学表现。这些肿瘤倾向于发生在上颌窦壁、蝶窦与筛窦及犁骨交界处以及蝶骨下表面。由于其生长缓慢的特性，软骨肉瘤在被发现时往往体积较大、呈多叶状且边界清晰。常见的骨质改变是侵蚀和破坏并存，有清晰的过渡区且无骨膜反应。肿瘤基质钙化（不一定是软骨样钙化）几乎总是存在。CT和MR对于全面评估肿瘤范围可能都有必要。
