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.
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.
一只3岁已绝育的雄性室内英国短毛猫因右前肢间歇性跛行2周前来就诊。影像学检查显示右侧尺骨干骺端有一个单骨、膨胀性、梭形、溶骨性病变。CT进一步明确了病变情况，并显示同侧肺部实变。组织学检查确诊为骨髓炎，需氧菌和厌氧菌培养以及真菌培养的微生物学和荧光原位杂交分析（FISH）均为阴性。抗炎治疗和短时间的初始抗菌治疗后，临床和影像学表现有所改善。
这是猫骨髓炎在干骺端皮质的一个不寻常的单骨位置，此外，可能代表一例罕见的无菌性骨髓炎。据我们所知，兽医文献中尚未报道猫在此位置的非创伤性骨髓炎。
