Plain-English summary
A 10-year-old female Labrador was brought in for sudden balance problems and a head tilt to the right. An MRI revealed a blockage in a blood vessel in the brain, which was likely caused by a blood clot, possibly related to an underlying cancer. The dog showed signs of a central vestibular syndrome, which affects balance and coordination. Treatment focused on managing the underlying condition and supporting her recovery. After treatment, the dog improved and regained better balance.

Abstract
Clinical signs and magnetic resonance imaging findings of a caudal cerebellar artery infarct are reported for the first time in a dog. Clinical signs were characterised by a peracute, non-progressive, right-sided central vestibular syndrome with paradoxical right-sided head tilt. Magnetic resonance images were consistent with a territorial, non-haemorrhagic, ischaemic lesion affecting the caudo-ventral part of the right cerebellar hemisphere, mainly involving the right paramedian lobe, the ansiform lobe and the caudal cerebellar peduncle. Bloodwork results were suggestive of an underlying hypercoagulable state, although the concomitant presence of a histologically confirmed mammary gland adenocarcinoma could have also been related to the cerebellar vascular obstruction through metastatic emboli formation. Posterior-inferior cerebellar artery infarction is the human equivalent of caudal cerebellar artery infarct in dogs.
