Abstract
Spinal strokes are often localised in the anterior spinal artery territory, whereas an involvement of the posterior spinal arteries (PSA) is uncommon, and usually unilateral. Bilateral PSA stroke is exceptional. A 70-year-old woman, after a mild head trauma, presented with cervical pain, left hypoaesthesia and sensitive ataxia, which then extended to the right hemibody, including face. A Doppler ultrasound showed an only systolic flow signal in the left vertebral artery (VA). MR showed a bilateral infarction extending from the posterior medulla oblongata to C4 and a left hypoplasic VA with lack of visualisation of the V3 segment. This case was peculiar, implying a bilateral stroke in the PSA territory, possibly related to a left VA dissection, and in the presence of a dominant PSA, originating from the hypoplasic VA and of hyposupply of posterior radiculomedullary arteries and anastomoses.
