(a) A 75-year old patient with mixed-type laryngopyocele presented with fever, right neck swelling, and shortness of breath. Plain lateral neck radiograph demonstrated air-fluid level (arrow) and swelling (asterisk) over the upper cervical paralaryngeal soft tissues, (b) Axial contrast-enhanced computed tomography image revealed cystic lesion with internal gas pockets and enhancing wall in the supraglottic region with epicenter at the right thyrohyoid membrane. It spanned medially (small arrow) and laterally (asterisk) to the hyoid bone crossing thyrohyoid membrane. Mass effect was noted with narrowing of the larynx (large arrow). The overall features were suggestive of a mixed-type laryngopyocele complicating airway obstruction (c and d) Axial and coronal contrast-enhanced computed tomography images showed marked narrowing of airway (arrow) by compressive effect of laryngopyocele. With signs of stridor and airway obstruction, subsequent intubation was performed for this patient.

Plain lateral neck radiograph demonstrated air-fluid level (arrow) and swelling (asterisk) over upper cervical parapharyngeal soft tissues [Figure 1a]. Overall features were suggestive of a mixed-type laryngopyocele complicating airway obstruction [Figure 1b]. With signs of stridor and airway obstruction, subsequent intubation was performed for this patient [Figure 1c and d].
