Abstract
OBJECTIVE AND IMPORTANCE: An exceedingly rare, isolated spinal arterial aneurysm and its management are presented. CLINICAL PRESENTATION: A 30-year-old man who presented with severe lower back pain and headache underwent a computed tomographic study of his head that disclosed nothing abnormal and a lumbar puncture that revealed bloody, xanthochromic cerebrospinal fluid. The findings from cerebral angiography were normal, and the results from spinal angiography were consistent with a diagnosis of an aneurysm of the artery of Adamkiewicz. INTERVENTION: A transthoracic approach with a partial T11 vertebrectomy gained exposure to this anteriorly located lesion. A fusiform aneurysm of the intradural portion of the artery of Adamkiewicz was discovered. Excision of the aneurysm with a vascular bypass was deemed impossible. The lesion was treated with muslin wrapping. One year after surgery, the patient remains at his baseline neurological condition. CONCLUSION: A review of the literature revealed only one other reported case of a ruptured aneurysm of the artery of Adamkiewicz, which was discovered postmortem. Therefore, this case represents the first report of a diagnosed and treated artery of Adamkiewicz aneurysm.
