Abstract :

[en] 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.
