They are typically diagnosed via magnetic resonance imaging and treated with laminectomy and excision.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>A 61-year-old male presented after a mechanical fall and had an incidentally discovered SAW on imaging. He was initially asymptomatic and was therefore conservatively managed. Several years later, however, the patient experienced new-onset back pain, paresthesia, and balance problems, with interval imaging demonstrating worsening of the edema surrounding his SAW. The patient subsequently underwent resection of the SAW, which led to significant resolution of his symptoms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>An SAW can be asymptomatic or can manifest with a wide variety of symptoms. When this condition is incidentally discovered in asymptomatic patients, neurosurgeons should guide these patients to follow-up urgently if they develop any neurological symptoms. At that time, further imaging can be performed to determine if surgical treatment is indicated. Although SAW is rare, clinicians should be aware of the signs and symptoms, because prompt surgical intervention can significantly improve neurological symptoms.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case23701","type":"journal-article","created":{"date-parts":[[2024,3,11]],"date-time":"2024-03-11T13:00:26Z","timestamp":1710162026000},"source":"Crossref","is-referenced-by-count":3,"title":["Resection of an incidentally discovered spinal arachnoid web: illustrative case"],"prefix":"10.3171","volume":"7","author":[{"given":"Vikas N","family":"Vattipally","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sina","family":"Ahmadi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carly","family":"Weber-Levine","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ann","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nancy","family":"Abu-Bonsrah","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jawad","family":"Khalifeh","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jordina","family":"Rincon-Torroella","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali","family":"Bydon","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Clin Imaging","first-page":"1","article-title":"Dorsal arachnoid web: a rare clinical entity","volume":"85","author":"Allen C","year":"2022","unstructured":"Allen C, Rao SJ, Raza R, Haas CJ Dorsal arachnoid web: a rare clinical entity.
