Plain-English summary
A 5-year-old domestic shorthair cat was brought in for noisy breathing and coughing. The veterinarian suspected a condition called dynamic pharyngeal collapse, which is when the throat partially collapses during breathing. Standard X-rays didn't show the problem, but a special test called fluoroscopy confirmed the diagnosis. In two of the three cats studied, a biopsy revealed high-grade B-cell lymphoma, a type of cancer. This case highlights the importance of using fluoroscopy to diagnose breathing issues in cats, especially when they have unusual upper respiratory sounds.

Abstract
Dynamic pharyngeal collapse (PC) is a rarely reported condition in cats defined as the partial or complete collapse of the pharyngeal lumen during inspiration. Herein, we report the imaging findings and clinical features of three cats with dynamic PC. Lateral radiograph of the head was insufficient to detect dynamic PC, but fluoroscopy in conscious cats revealed dynamic PC. Magnetic resonance imaging was not helpful to reveal dynamic PC and underlying diseases. We obtained biopsy samples from the irregular nasopharyngeal mucosal membrane through endoscopy in two of the three cases and high-grade B-cell lymphoma was histopathologically diagnosed. In feline cases with abnormal upper respiratory sounds, dynamic PC should be considered, and fluoroscopy is the imaging technique of choice to diagnose the condition.
