Patient 10. Patient 10. A 67-year-old man after radiation therapy at an outside hospital for base-of-tongue cancer. A and B, Axial contrast-enhanced CT scans show an air-filled soft-tissue defect in the left posterior tongue (arrow, A). Lower down, this communicates with the hyoid (B). There is an unrelated nodal recurrence in the right neck (arrowhead, A). B, Soft-tissue CT image more inferiorly shows air (arrowheads) and fluid (arrows) surrounding the hyoid. C, CT bone window shows intraosseous air (arrowheads) and a hyoid fracture (arrow). J.S. Yoo et al. AJNR Am J Neuroradiol 2010;31:761-766 ©2010 by American Society of Neuroradiology
