Posterior spinal artery infarcts are exceedingly rare due to high level of collateral circulation in the spinal cord. Additionally thromboembolic phenomenon is a potential complication during aneurysm stenting via digital subtraction angiography (DSA). Hereby, we report a case of posterior spinal artery syndrome following cerebral angiography and endovascular basilar artery pipeline embolization (PED) for basilar artery aneurysm. Our goal is to outline successful diagnosis and management of this rare event. Our patient is a 59-year-old female with a basilar artery aneurysm. Following treatment of an intracranial proximal basilar artery aneurysm with a Pipeline Embolization Device, she presented as bilateral dorsal cord syndrome. On exam, she had isolated findings of loss of vibration and joint position sense in her feet and ankles, accompanied by the presence of T2 hyperintensity in the nuclei gracilis at C2-3 on MRI cervical spine is consistent with arterial thromboembolism during her procedure. Although posterior spinal artery infarct is infrequently reported in the literature, it is a potential complication of posterior fossa endovascular intervention. The presence of sensory symptoms following a basilar artery procedure should alert physicians to involvement of the dorsal columns of the upper cervical cord due to PSA ischemia.
