FIG 1. Axial contrast-enhanced CT image of a 67-year-old male patient with a glottic cancer (T2N0). A left-sided glottic soft tissue mass is seen (arrowheads). The tumor abuts the left arytenoid, which shows a clearly increased attenuation (arrows; compare with opposite side). Extended hemilaryngectomy was performed. No postoperative radiation therapy was administered. There is no evidence of disease 2 years after surgery.

FIG 2. Axial contrast-enhanced CT-images in a 55-year-old male patient with a glottic cancer (T3N0).
A, Level of true vocal cords. The left true vocal cord appears thickened and slightly enhancing. The tumor reaches the anterior commissure (black arrowhead). The left paraglottic space is infiltrated. Marked sclerosis of the left arytenoid (white arrowhead). The left thyroid lamina also shows some increased attenuation (arrow).
B, Level of subglottis. Enhancing soft tissue thickening on left side (arrowheads). Note slight sclerosis of cricoid arch on the left (curved arrow). Slight enhancement is seen anteromedially to the subglottis, corresponding to subtle extralaryngeal tumor spread or peritumoral inflammation (arrow).
C, Level of false vocal cords. Soft tissue infiltration of the left paraglottic space along the thyroid cartilage, which shows slightly increased attenuation (arrows; compare with opposite side). Area of nonossified thyroid cartilage (arrowhead), most likely normal variant. The patient was treated by extended hemilaryngectomy. No postoperative radiation therapy was administered. There is no evidence of disease 7 years after treatment.
