Rotation-induced vertebral artery compression and occlusion with the outcome of cerebellar infarction (as opposed to the outcome of transient ischemia from hemodynamic insufficiency, known as bow hunter's stroke) is extremely rare. We report a 40-year-old male who suffered from ipsilateral neck-rotation-induced right vertebral artery compression and occlusion that resulted in right cerebellar infarction. In most reported cases, the rotation-compressed vertebral artery is located at the C1–2 level; however, our patient's compressed artery was located at the C6–7 level as demonstrated clearly by 3-dimensional CT angiography. This case report is based on a literature review and an investigation of the likely factors of this specific incident via the patient's personal details, clinical course, and diagnostic images.
