“…There have been no comprehensive reports on the imaging findings of the variants of laryngeal chondrosarcomas, such as clear cell chondrosarcomas, myxoid chondrosarcomas, and dedifferentiated chondrosarcomas. Case reports have shown that these variants, as well as chondrosarcomas and chondromas, have low density, well‐defined margins, internal calcification (or no calcification), and cortical bone defect/expansion on CT imaging, suggesting that they may be difficult to differentiate on imaging 48–50 …”

Background and Purpose To comprehensively summarize the characteristics of radiological findings of laryngeal conventional chondrosarcomas. Methods We included patients with pathologically proven laryngeal conventional chondrosarcomas with CT and /or MRI, including 41 cases from 31 publications recruited after a systematic review and 14 cases from our institution. Two board‐certified radiologists reviewed and evaluated all the radiological images. The relationship between pathological grade and radiological findings was analyzed. Results The median long diameter of the lesion was 3.1 cm (range, 1.5‐8.5 cm). The most common location was the cricoid (74.5%), followed by the thyroid (12.7%), cricoid and thyroid (7.3%), and arytenoid (5.5%). All lesions showed well‐defined margins. Cortical defect/expansion (98.0%), internal low density (89.6%), and calcification (95.8%) with homogeneous and scarce contrast enhancement on contrast‐enhanced CT (85.3%) were frequently observed. All cases showed high signal on T2‐weighted imaging, low signal on T1‐weighted imaging (T1WI), and heterogeneous and mild contrast enhancement on postcontrast T1WI. No significant differences were found between the pathological grades and radiological findings. Conclusions In our summary of comprehensive CT and MRI findings of laryngeal conventional chondrosarcomas, we found that the knowledge of these radiological features may facilitate prompt diagnosis and appropriate management.
