Fig. 4

A 73-year-old male heavy smoker presented with hoarseness of voice, dysphagia, and stridor. A Laryngeal ultrasound right lateral axial view with right thyroid cartilage (asterisk) as anatomical landmark, shows a large soft tissue isoechoic mass lesion (arrow) almost completely replacing the right VC with ill-defined lateral portion of the right thyroid cartilage, indicating invasion. No related cervical LNs were detected. B Colored Doppler sonographic images revealed that the lesion has an internal color signal (curved arrow) denoting its hypervascularity. C Flexible laryngoscopy of the same patient shows the lesion in the posterior part of the right vocal cord (arrow head). The anterior is at the bottom of this figure. The flexible laryngoscopy confirmed the sonographic findings, yet it is limited in estimation of the proper size and extension of the subglottic component
