动态咽部塌陷（PC）是一种很少报道的猫的情况，定义为吸气时咽腔部分或完全塌陷。在此，我们报告了三只动态PC猫的影像学表现和临床特征。头部侧位片不足以检测到动态PC，但清醒猫的x线检查显示动态PC。磁共振成像对动态PC和潜在疾病的显示没有帮助。我们在三个病例中的两个通过内窥镜从不规则的鼻咽粘膜获得活检样本，并通过组织病理学诊断为高级别b细胞淋巴瘤。在有异常上呼吸道音的猫病例中，应考虑动态PC，而x线透视是诊断该病症的首选影像学技术。
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.
