A five-month-old Maine Coon tomcat was presented with acute non-ambulatory paraparesis and severe spinal hyperaesthesia. Neurological examination was consistent with a spinal cord lesion between the third thoracic and the third lumbar segment. Diagnostic imaging and further laboratory work revealed an extradural mass consisting of sterile pyogranulomatous inflammation and necrosis of the epidural adipose tissue of unknown origin compressing the spinal cord dorsally at the 12th thoracic vertebra. The cat recovered well after surgical decompression and regained ambulation over the next three months. To the authors’ knowledge, this is the first report of an idiopathic sterile pyogranulomatous inflammation of epidural fat in a cat. Although rare, this disease should be included as a possible differential diagnosis for a paraparetic cat.
