Plain-English summary
A 2-year-old neutered male European Shorthair cat was brought to the vet because he had been developing multiple bone growths over three months and was making a strange noise when breathing (stridor). X-rays showed bone masses in several areas, and a CT scan found additional masses, including one on the bone near his throat that was likely causing the breathing issue. The diagnosis was feline osteochondromatosis, a condition where abnormal bone growth occurs. The owner chose not to proceed with surgery to remove the mass due to the risk of it coming back.

Abstract
A 2-year-old neutered male European Shorthair cat was presented for multiple bone proliferations evolving over 3 months and stridor. The osseous masses on the tarsus, vertebral column, and distal third of ribs diaphysis were confirmed by radiographs. A whole-body CT examination was performed, revealing two other masses, one on the left calvarium and one arising from the left epihyoid bone, with the latter thought to be responsible for the stridor. Histopathology confirmed a diagnosis of feline osteochondromatosis. Surgical removal of the epihyoid mass was declined due to the high recurrence rate reported.
