“…The anterior spinal artery (ASA) territory is more often affected because the posterior cord is protected by a pial collateral network and dual posterior spinal arteries (PSA) . Concomitant ischemia can lead to varied clinical manifestations, especially with cardinal sensory symptoms . Etiology is variable as traditional stroke risk factors are less applicable.…”

“…Most people have 4–10 anterior radicular arteries and 10–23 posterior radicular arteries. The posterior spinal arteries, therefore, comprise plexiform channels, rather than separate arteries due to their number of anastomotic channels 2. Therefore, infarction in the distribution of the posterior spinal arteries is extremely rare.…”

Posterior spinal artery syndrome has a variable presentation and often poses a clinical challenge. We describe an acute posterior spinal artery syndrome in a man in his 60s with vascular risk factors, who presented with altered sensation in the left arm and left side of his torso but with normal tone, strength and deep tendon reflexes. MR imaging showed a left paracentral T2 hyperintense area affecting the posterior spinal cord at the level of C1. Diffusion-weighted MRI (DWI) showed high signal intensity in the same location. He was medically managed as having ischaemic stroke and made a good recovery. Three-month MRI follow-up showed a persisting T2 lesion but the DWI changes had resolved, consistent with the time course for infarction. Posterior spinal artery stroke has a variable presentation and is probably under-recognised clinically, requiring careful attention to MR imaging for its diagnosis.

“…Most individuals have 4-10 anterior radicular arteries, as well as 10-23 posterior radicular arteries. 1 The posterior spinal arteries are smaller in diameter and more evenly distributed than the anterior ones. Furthermore, patients with infarction of the spinal artery region range from young to old, whereas cerebral artery infarction occurs much more often in the elderly.…”

Objective: To describe a rare autopsy case of posterior spinal artery syndrome with marked swelling of the spinal cord, an unusually subacute onset and short clinical course. Methods: Case report. Findings: An 84-year-old Japanese woman presented with bilateral muscle weakness of the lower legs and sensory disturbance 1 week after head contusion. Neurological findings worsened gradually. She developed phrenic nerve paralysis and died of respiratory failure 6 weeks after the onset of neurological symptoms. On pathological examination, the spinal cord was markedly swollen in the cervical and upper thoracic segments. Microscopically, there was loss of myelin sheath in the bilateral posterior columns and neuronal loss of the posterior horns in all of the spinal segments. However, findings were unremarkable in the bilateral anterior columns and bilateral anterior horns in most of the spinal segments. Posterior spinal arteries had no stenosis, occlusion, or thrombosis. We considered that pathogenesis was infarction associated with head injury. Conclusion: To our knowledge, this is the first report of a case of posterior spinal artery syndrome with a markedly swollen spinal cord and poor prognosis.
