Contrast enhanced CT of a 62 year old male with T4 N2b M0 squamous carcinoma of the left supraglottic larynx treated successfully with chemoselection. (A) Contrast enhanced CT scan at time of diagnosis demonstrates an aggressive appearing left supraglottic mass with erosion through the left lateral aspect of the thyroid cartilage. (B) Three weeks after a single induction cycle of cisplatin-fluorouracil, a greater than 50% tumor response was achieved. (C) CT at 6 months after completion of chemoradiation demonstrated residual left supraglottic tissue fullness attributable to post-radiotherapy change without evidence of residual disease, confirmed on endoscopic examination. The patient remains disease free 2 years after completion of therapy.
