fig 1.

Axial view contrast-enhanced CT scan of a 21-year-old man who consulted for dysphagia associated with dyspnea that worsened when lying supine. A homogeneous, well-demarcated mass can be seen, seemingly arising from the right lateral wall of the oro- and hypopharynx (arrow), associated with a homolateral deep cervical node (curved arrowhead). No recurrence had occurred 5 years after surgery, chemotherapy, and radiotherapy.

fig 2. Images from the case of a 17-year-old male patient who consulted for a painless progressively enlarging neck mass and complained of dyspnea.

A, Initial non-contrast-enhanced axial view CT scan reveals a left hypopharyngeal mass involving the left piriform sinus (black arrow).

B, Axial view contrast-enhanced CT scan, obtained 3 months after partial resection under endoscopic guidance and carbon dioxide laser therapy, shows a heterogeneous, multilocular recurrence of the tumor (white arrow)
