Here, we present a patient who developed recurrent bilateral lower extremity paraplegia secondary to spinal cord infarction 1 day after a successful L4-5 microdiscectomy in a patient who originally presented with a cauda equina syndrome.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description:<\/jats:title>\n<jats:p>A 56-year-old patient presented with an acute cauda equina syndrome characterized by severe lower back pain, a right foot drop, saddle anesthesia, and acute urinary retention. When the lumbar magnetic resonance imaging (MRI) revealed a large right paracentral lumbar disc herniation at the L4-L5 level, the patient underwent an emergency minimally invasive right-sided L4-5 discectomy. Immediately, postoperatively, the patient regained normal function. However, 1 day later, while having a bowel movement, he immediately developed the recurrent paraplegia. The new lumbar MRI revealed acute ischemia and an infarct involving the distal conus medullaris. Further, workup was negative for a spinal cord vascular malformation, thus leaving an inflammatory postsurgical vasculitis as the primary etiology of delayed the conus medullaris infarction.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusions:<\/jats:title>\n<jats:p>Acute neurologic deterioration after spinal surgery which does not neurologically correlate with the operative level or procedure performed should prompt the performance of follow-up MR studies of the neuraxis to rule out other etiologies, including vascular lesions versus infarctions, as causes of new neurological deficits.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni-148-2019","type":"journal-article","created":{"date-parts":[[2019,8,25]],"date-time":"2019-08-25T12:02:39Z","timestamp":1566734559000},"page":"80","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Spinal
