To define the typical CT features of chondrosarcoma of the larynx.
Results of CT studies, performed on 10 patients with pathologically proved chondrosarcoma of the larynx, were retrospectively reviewed and correlated with clinical presentation.
In all patients, the mass was detected on CT. The most frequent site of origin of the tumor was the cricoid cartilage (nine cases) followed by the thyroid cartilage (one case). Coarse or stippled calcification within the tumor was the most helpful radiologic finding and was seen in every case. In eight patients, the tumor had both an endolaryngeal and an extralaryngeal growth pattern, whereas in two patients the tumor was entirely endolaryngeal. Hoarseness, dyspnea, and dysphagia were the most common symptoms. In all patients presenting with dyspnea, the tumor exhibited endolaryngeal components. In patients presenting with hoarseness, three tumors had endolaryngeal and extralaryngeal components and two tumors were entirely endolaryngeal.
Cross-sectional imaging afforded excellent evaluation of the airway as well as the extralaryngeal component of the tumor.
明确喉软骨肉瘤的典型CT特征。
对10例经病理证实为喉软骨肉瘤患者的CT研究结果进行回顾性分析，并与临床表现相关联。
所有患者CT均发现肿物。肿瘤最常见的起源部位是环状软骨（9例），其次是甲状软骨（1例）。肿瘤内粗大或点状钙化是最有帮助的影像学表现，每例均可见。8例患者肿瘤呈喉内及喉外生长模式，2例患者肿瘤完全位于喉内。声音嘶哑、呼吸困难和吞咽困难是最常见症状。所有出现呼吸困难的患者，肿瘤均有喉内成分。出现声音嘶哑的患者中，3例肿瘤有喉内及喉外成分，2例肿瘤完全位于喉内。
横断面成像能很好地评估气道以及肿瘤的喉外成分。
