2-years-old male neutered cat. No other symptoms except rattling since he was rescued. He does not sneeze or had secretions since the owner had it. No improvement with antibiotics or steroids. A head CT scan was performed
Description
There is a partial stenosis at the most caudal aspect of the nasopharynx (orange arrows). At this level, the lumen of the nasopharynx decreases circumferentially (blue line) in comparison to its rostral aspect (yellow line), remaining aerated without presence of nodules or masses.
Central image: orange arrows marking the area of nasopharyngeal stenosis. Left and right images: showing the rostral and caudal aspect of the area of nasopharyngeal stenosis, where the nasopharynx has a normal size (yellow arrows).
Diagnosis
- Findings in nasopharynx consistent with a focal nasopharyngeal stenosis at its caudal aspect, without associated nodules or masses. Its lumen remains aerated without secretions.
comments
The findings are consistent with nasopharyngeal stenosis, which could be causing the symptoms described (stertor). The aetiology is uncertain; however, considering the history, it could be associated with an inflammatory / infectious (viral) process.
