Chondrosarcomas of the head and neck represent a small percentage and differ in their treatment and prognosis compared with chondrosarcomas elsewhere. Four different cases of chondrosarcoma are presented. One arose intracranially, two in the jaws, one of which followed irradiation for a retinoblastoma, and the last represents chondrosarcomatous transformation in cervical spine Paget disease which is exceptionally rare. Computer tomography (CT) plays an important role in delineating the extent of the tumor with visualization of bony destruction, associated soft-tissue mass, and calcification, information which is extremely important for surgical and therapeutic planning. CT can be vital in suggesting the best possible site for biopsy which is particularly important in this group of neoplasms where the histological diagnosis may be difficult.
头颈部软骨肉瘤占比小，与其他部位的软骨肉瘤相比，其治疗方法和预后有所不同。本文介绍了四例不同的软骨肉瘤病例。一例发生于颅内，两例发生于颌骨，其中一例是在视网膜母细胞瘤放疗后发生，最后一例是颈椎佩吉特病中极为罕见的软骨肉瘤样化生。计算机断层扫描（CT）在确定肿瘤范围方面发挥着重要作用，可显示骨质破坏、相关软组织肿块和钙化情况，这些信息对于手术和治疗规划极为重要。CT对于提示最佳活检部位至关重要，这在这类难以进行组织学诊断的肿瘤中尤为重要。
