The patient presented with a left-sided head tilt and right-sided hemiparesis. Magnetic resonance imaging (MRI) revealed a right-sided extra-axial cavitated lesion in the cerebellum, and mild right-sided otitis media without evidence of otitis interna. Surgical decompression was performed, guided by the use of a 3D-printed model, and purulent material was evacuated. Bacterial culture identified <jats:italic>Peptostreptococcus canis<\/jats:italic>, <jats:italic>Filifactor villosus,<\/jats:italic> and a Gram-negative rod population; all were suspectible to amoxicillin-clavulanic acid. Cerebellar subdural lesion histopathologic analysis confirmed a pyogranulamatous to lymphoplasmocytic inflammatory process. The patient showed rapid postoperative neurological improvement and was discharged with targeted antimicrobial therapy. Follow-up MRI at 2\u202fmonths revealed resolution of the cerebellar lesion but progression of right-sided otitis media without evidence of otitis interna. A ventral bulla osteotomy was subsequently performed, and tympanic mucosa biopsy confirmed chronic inflammation with cholesterol granuloma formation. To our knowledge, this is the first report of successful surgical treatment of a cerebellar subdural empyema in a feline patient.<\/jats:p>","DOI":"10.3389\/fvets.2025.1655305","type":"journal-article","created":{"date-parts":[[2025,9,15]],"date-time":"2025-09-15T04:13:08Z","timestamp":1757909588000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Successful
