Plain-English summary
A 3-year-old neutered male British Shorthair cat was brought to the vet for a 2-week history of limping on his right front leg. X-rays revealed a concerning bone lesion in his right ulna, and further tests showed signs of osteomyelitis, which is an infection of the bone. However, tests for bacteria and fungi came back negative, suggesting it was a rare case of sterile osteomyelitis, meaning there was no infection present. After starting anti-inflammatory medication and a short course of antibiotics, the cat showed improvement in both his symptoms and the radiographic findings.

Abstract
Case summary A 3-year-old neutered male indoor British Shorthair cat was referred for a 2-week history of intermittent right forelimb lameness. Radiographic examination showed a diaphyseal monostotic, expansile, fusiform, lytic lesion in the right ulna. CT further defined the lesion and also demonstrated ipsilateral pulmonary consolidation. Histology was conclusive of osteomyelitis, and microbiology and fluorescence in situ hybridisation analysis (FISH) were negative on aerobic and anaerobic bacterial culture, as well as fungal culture. Clinical and radiographic improvement was seen after anti-inflammatory treatment and a short initial period of antibiosis. Relevance and novel information This is an unusual monostotic diaphyseal cortical location for osteomyelitis in cats and, moreover, may represent a rare case of sterile osteomyelitis. To our knowledge, non-traumatic osteomyelitis in this location in cats has not been reported in the veterinary literature.
