This is a unique case of extradural AVF of the cervical spine manifesting with purely radicular symptoms and treated endovascularly with coil and liquid embolization.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description: <\/jats:title>\n<jats:p>A 55-year-old woman presented with neck pain and right upper extremity radiculopathy persisting for 9 months. Imaging studies demonstrated an AVF spanning from C4\u2013C6 with extension into the C5\u2013C6 foramen supplied primarily from the deep cervical branch of the costocervical trunk. The patient underwent successful coil and liquid (Onyx) embolization. Six-week postoperatively, the patient\u2019s symptoms completely resolved and magnetic resonance imaging and angiographic imaging confirmed complete obliteration of the fistula.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>While extradural AVFs typically present with myelopathic symptoms, they may present with solely radicular symptoms and can be successfully treated endovascularly.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_306_2023","type":"journal-article","created":{"date-parts":[[2023,7,28]],"date-time":"2023-07-28T07:29:12Z","timestamp":1690529352000},"page":"265","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Cervical extradural arteriovenous fistula with radiculopathy managed endovascularly"],"prefix":"10.25259","volume":"14","author":[{"given":"Gabrielle","family":"Santangelo","sequence":"first","affiliation":[{"name":"Department of Neurosurgery,University of Rochester, Strong Memorial Hospital, Rochester, New York, United States."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aman","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery,University of Rochester, Strong Memorial Hospital, Rochester, New York, United States."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Redi","family":"Rahmani","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery,University of Rochester, Strong Memorial Hospital, Rochester, New York, United States."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Kessler","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Rochester, Strong Memorial Hospital, Rochester, New York, United States."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew","family":"Bender","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery,University of Rochester, Strong Memorial Hospital, Rochester, New York, United States."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2023,7,28]]},"reference":[{"key":"10.25259\/SNI_306_2023\/ref-1","first-page":"1372","article-title":"Exclusively epidural arteriovenous fistula in the cervical spine with spinal cord symptoms: Case report","volume":"48","author":"Asai","year":"2001","journal-title":"Neurosurgery"},{"key":"10.25259\/SNI_306_2023\/ref-2","doi-asserted-by":"crossref","first-page":"144","DOI":"10.7461\/jcen.2022.E2021.12.003","article-title":"Comparison of transarterial n-BCA and Onyx embolization of brain arteriovenous malformations: A single-center 18-year retrospective analysis","volume":"24","author":"Behzadi","year":"2022","journal-title":"J Cerebrovasc Endovasc Neurosurg"},{"key":"10.25259\/SNI_306_2023\/ref-3","first-page":"75","article-title":"Classification and Therapeutic Modalities of Spinal Vascular Malformations in 80 Patients","volume":"40","author":"Bao","year":"1997","journal-title":"Neurosurgery"},{"key":"10.25259\/SNI_306_2023\/ref-4","doi-asserted-by":"crossref","first-page":"755","DOI":"10.3171\/2019.11.SPINE19798","article-title":"Clinical and angioarchitectural characteristics of spinal vascular malformations of the cervical spine","volume":"32","author":"Brinjikji","year":"2020","journal-title":"J Neurosurg Spine"},{"key":"10.25259\/SNI_306_2023\/ref-5","doi-asserted-by":"crossref","first-page":"161","DOI":"10.1016\/B978-0-444-63640-9.00016-3","article-title":"Endovascular treatment of spinal arteriovenous malformations","volume":"143","author":"Brinjikji","year":"2017","journal-title":"Handb Clin Neurol"},{"key":"10.25259\/SNI_306_2023\/ref-6","doi-asserted-by":"crossref","first-page":"1065","DOI":"10.1148\/88.6.1065","article-title":"Selective arteriography of arteriovenous aneurysms of spinal cord","volume":"88","author":"di Chiro","year":"1967","journal-title":"Radiology"},{"key":"10.25259\/SNI_306_2023\/ref-7","doi-asserted-by":"crossref","first-page":"108","DOI":"10.2176\/nmc.49.108","article-title":"Cervical epidural arteriovenous fistula with radiculopathy mimicking cervical spondylosis","volume":"49","author":"Kawabori","year":"2009","journal-title":"Neurol Med Chir (Tokyo)"},{"key":"10.25259\/SNI_306_2023\/ref-8","doi-asserted-by":"crossref","first-page":"119","DOI":"10.3171\/jns.1996.84.1.0119","article-title":"A cervical dural arteriovenous fistula in a patient presenting with radiculopathy.
