15y M Domestic Shorthair with stertor, sneezing, and progressive open‐mouth breathing. The left and right nasal passages are completely
opacified with soft tissue material, but bony turbinates are largely preserved (a: arrows). The left and right maxillary recesses, the
nasopharynx (c: open arrow), and the left frontal (d: black open arrow) and sphenopalatine (d: asterisk) sinuses are also completely
opacified with soft‐tissue or fluid attenuating material. The dorsal wall of the nasopharynx appears irregular and thickened (d: black
arrow), and the nasopharyngeal lumen is narrowed. Rhinoscopy revealed polypoid pharyngeal mucosal inflammation (e), and
Cryptococcus neoformans was cultured from the tissue.
