title: Multiple Cerebral Infarctions due to Unilateral Traumatic Vertebral Artery Dissection after Cervical Fractures.
abstract: We report a case of multiple symptomatic cerebral infarctions from a traumatic vertebral artery dissection (VAD) after cervical fractures. A 73-year-old man was admitted with stuporous mentality and left hemiparesis after a motor-vehicle accident. A brain computed tomography (CT) scan at admission showed a traumatic subarachnoid hemorrhage on the left parietal lobe. A cervical CT scan showed left lateral mass fractures on C2, C5, and C6, involving the transverse foramen. Cervical spine magnetic resonance imaging (MRI) revealed loss of signal void on the left vertebral artery. Neck CT angiography showed left VAD starting at the C5 level. Brain MRI revealed acute, multiple cerebral infarctions involving the pons, midbrain, thalamus, corpus callosum, and parietal and frontal lobes on diffusion weighted images. The patient was treated conservatively at the intensive care unit in the acute stage to prevent extent of stroke. Aspirin was started for antiplatelet therapy in the chronic stage. The possibility of symptomatic cerebral infarctions due to traumatic VAD following cervical fracture should be considered.
