Pre-RT enhanced CT scans at the level of the true vocal cords in a patient with a T3 glottic carcinoma and sclerosis of the arytenoid and cricoid cartilages on the left. Calculated tumor volume was 4.3 mL. The patient elected curative RT alone, though the likelihood of control was <20% based on the CT risk profile. Because of the high risk of recurrence, close post-treatment surveillance with CT was chosen. Treatment failed, and total laryngectomy was performed.

A, Soft tissue window shows cancer of the true vocal cords on the left (arrow) without involvement of the anterior commissure (arrowhead).

B, Bone window shows sclerosis of the left lingual cortex of the left lamina of the thyroid cartilage (arrowhead) and the left arytenoid cartilage (arrow).
