A, Sonogram shows a poorly defined hypoechoic mass (arrows) on the right side of the neopharynx, which obliterates the outer three layers of the neopharynx.
B, CT scan shows a less discrete isodense mass (arrow) on right side of the neopharynx. Recurrent squamous cell carcinoma was confirmed pathologically.
