Fig. 2From: CT-based radiomics features in the prediction of thyroid cartilage invasion from laryngeal and hypopharyngeal squamous cell carcinomaa Axial CE-CT image. Histopathology confirmed thyroid cartilage invasion in a 57-year-old man with supraglottic laryngeal carcinoma. Thyroid cartilage shows focal erosion (white arrow) that involves the inner cortex but do not penetrate the outer cortex, which is defined as minor invasion. b Axial CE-CT image for a 61-year-old man depicts a large tumor at the level of the glottic region that penetrates the right thyroid cartilage and presents as an extralaryngeal mass (white arrow) and thyroid cartilage is lysis, which was defined as major invasionBack to article page
