Figures
- Fig 1.
Postcontrast CT scan at the level of the false vocal cords showing bilateral circumscribed, homogeneous, low-signal-intensity lesions of the thyroid cartilage (arrows).
- Fig 2.
A, Precontrast axial spin-echo T1-weighted image showing a homogenous soft tissue mass (arrows), isointense to muscle, and located in the wall of the larynx lateral to the pre-epiglottic fat, medially to laryngeal muscle strap.
B, Axial fast spin-echo T2-weighted image at the level of the false vocal cords, showing a pronounced high signal intensity of the bilateral well-circumscribed lesion of the thyroid cartilage (arrowheads).
- Fig 3.
CT scan image taken 2 years after the initial examination, showing the progressive calcification of the lesion, with a cartilaginous matrix aspect (arrows). Note the relationship of the lesion to the noncalcified thyroid plate.
- Fig 4.
Fat saturation postcontrast axial spin-echo T1-weighted image showing a bilateral pronounced enhancement of the thyroid cartilage (arrowheads).
- Fig 5.
Schematic representation of the mechanical forces in the area of muscular insertion of the thyroid plate (external side). The black arrow illustrates the thyrohyoid muscle force, the dark gray arrow the thyropharyngeal part of the inferior constrictor muscle of the pharynx, and the light gray arrow the sternothyroid muscle.
