Abstract
Case summary
A 2-year-old cat was presented with nasopharyngeal stridor and stertor. Radiographs of the upper neck region showed a mass lesion in the nasopharynx. A nasopharyngeal polyp was suspected, but an attempt at endoscopic removal failed, owing to fragmentation of the mass and excessive haemorrhage. A sample was taken and histology confirmed a dermoid cyst. CT was performed and the lesion was described as most likely to be a dermoid cyst, consistent with the histopathological findings. Surgical exploration and subsequent complete removal of the mass led to a full recovery.
Relevance and novel information
The nasopharyngeal location represents a previously unreported location of a dermoid cyst. This report raises awareness of dermoid cysts as a potential differential diagnosis within the nasopharyngeal region and highlights the importance of pre-interventional diagnostic imaging.
