Kato et al. described a method of using standard T2-weighted MRI sequencing in the coronal plane parallel to the sylvian vallecula with gray-scale reversal during post-processing that is superior to MRA in detecting MCAD.
Lateral radiograph of the neck shows thickening of the retropharyngeal soft tissue (asterisk), enlargement of the epiglottis with narrowing of the vallecula (large arrow), and thickening of the aryepiglottic folds (small arrow).
We present a case of a 55 years old man with a lateral cervical left mass, and an expansive lesion in lingual epiglottis versant, on the right side (involving ipsilateral epiglottic vallecula).
The vallecula, a groove that houses a large blood vessel and demarcates the lateral border of the Wulst in many avian species, is extremely shallow and relatively medially placed in Kiwi, with the result that the Wulst cannot be identified as a definitive bulge on the dorsum of the hemisphere, as it can in other avian species (Figs 2 and 4).
Pan-endoscopy revealed suspicious thickening in right vallecula and adjacent base of tongue.
Indeed, VT has minor bifurcations: the piriform sinuses (sinus piriformes) and vallecula.
The ability to distinguish the uvula, epiglottis, aryepiglottic fold, vallecula, piriform sinus, true vocal cord, and false cord was assessed.
The view obtained includes the tip of the blade and, therefore, allowing for guiding the tip of the blade into the vallecula under vision.
Case 4 in our series, showed local recurrence in vallecula, with an isolated site of distant metastases in myocardium; in the absence of nodal disease.
It was difficult to appreciate the uvula, epiglottis, aryepiglottic fold, vallecula, piriform sinus, true vocal cords, and false cords on CT in our rabbit model.
The uvula, epiglottis, aryepiglottic fold, vallecula, piriform sinus, true/false vocal cords, and pre-epiglottic/paraglottic fat were not seen in any rabbit.
