Spontaneous resolution of a suspected nasopharyngeal polyp in a young cat

To detail a case of a suspected inflammatory nasopharyngeal polyp, in a young cat, that disappeared without medical or surgical therapy.

A 5-month-old neutered male domestic shorthair cat that was client-owned and indoor-only.

Serial head computed tomographic scans were done on a young cat to diagnose and monitor the size and location of the suspected inflammatory nasopharyngeal polyp.

At 145 d after diagnosis of a suspected inflammatory nasopharyngeal polyp in a young cat via head computed tomographic scan, the mass was no longer present. The cat had not undergone any surgical or medical therapy from Day 0 to Day 145.

Although the standard of care for nasopharyngeal polyps in cats is to conduct the appropriate diagnostics and surgical treatment, this case may provide an alternative management approach if surgical treatment is not feasible or euthanasia is being considered.

This article presents a case in which a nasopharyngeal mass, a suspected inflammatory polyp, in a young cat spontaneously resolved with no medical or surgical intervention.
