Plain-English summary
A 15-year-old female spayed domestic long-haired cat was brought to the vet for difficulty closing her mouth (trismus), excessive drooling (hypersalivation), and eye discharge. The vet found pain in her face and limited movement of her eyes. A special CT scan showed serious damage to her skull and signs of a rare and aggressive cancer called sinonasal adenosquamous carcinoma. Unfortunately, the cat did not survive, and the biopsy confirmed the diagnosis after she passed away.

Abstract
A 15-year-old female spayed domestic long-haired cat was referred for trismus, hypersalivation, and bilateral ocular discharge. On examination, the cat showed pain on palpation of the left zygomatic arch, palpable crepitus of the frontal region, and limited retropulsion of both globes. A contrast-enhanced sinonasal computed tomographic study was performed, showing facial distortion and extensive osteolysis of the skull, extending beyond the confines of the sinonasal and paranasal cavities. Additionally, soft tissue and fluid accumulation were observed in the nasal cavities and paranasal sinuses. Postmortem biopsy samples acquired from the calvarium yielded a histologic diagnosis of sinonasal adenosquamous carcinoma, a rare and particularly aggressive neoplasm previously only reported in the esophagus of one cat.
