Cervical Posterior Spinal Artery Syndrome: A Case Report and Literature Review

      We report a case of left upper cervical posterior spinal artery (PSA) syndrome caused by atherosclerosis of the left vertebral artery. A 70-year-old female experienced sudden dizziness and paralysis of the left upper and lower limbs. Diffusion-weighted magnetic resonance imaging (DWI) of the brain showed high signal intensity at the vermis and lower left hemisphere of the cerebellum, and magnetic resonance angiography showed that the entire left vertebral artery was thin. The patient was treated with an intravenous infusion of tissue plasminogen activator 2 hours after symptom onset and made a full recovery. Repeat DWI, fluid-attenuated inversion recovery images, and T2-weighted images showed high signal intensity in the left upper cervical PSA area from the lower medulla oblongata to the C2 level in addition to the cerebellum. Previously reported cases of cervical posterior artery syndrome are reviewed.
