The identification of cartilage involvement in laryngeal carcinoma implies advanced stage T4 disease. Although computed tomography (CT) provides the most accurate method of assessing these cartilages, subtle cartilage invasion may go undetected. The major pitfall in detecting tumor involvement is the incomplete calcification of these structures, which may simulate cartilage destruction. High-resolution CT now allows the evaluation of the medullary space of these cartilages. The CT finding of abnormal soft tissue in the central medullary space in addition to a focal cortical defect allows the confident diagnosis of cartilage involvement.
喉癌中软骨受累的识别意味着疾病处于晚期T4期。尽管计算机断层扫描（CT）提供了评估这些软骨的最准确方法，但细微的软骨侵犯可能无法被检测到。检测肿瘤受累的主要陷阱是这些结构的钙化不完全，这可能会模拟软骨破坏。高分辨率CT现在允许对这些软骨的髓腔进行评估。除了局灶性皮质缺损外，CT发现中央髓腔内有异常软组织，这有助于确诊软骨受累。
