This specific subtype is characterised by spinal venous drainage into peri-medullary veins, which presents as progressive or ascending myelopathy in 50% of cases. Case Presentation: A 59-year-old man with 3 weeks of worsening quadriparesis, along with abnormal sensory findings, gait deterioration, and bowel and bladder dysfunction, was admitted to the hospital. MRI revealed extensive T2 hyper-intense signal changes in the brainstem and myelopathy in the cervical spinal cord extending down to C7. The differential diagnosis for extensive myelopathy and brainstem lesions seen on MRI included a tumour, autoimmune inflammation, and suspicion of vascular malformation. The administration of corticosteroids resulted in a worsening of the patient\u2019s neurological symptoms. Conventional angiography confirmed the presence of a dural AVF (a small arteriovenous short shunt receiving arterial supply from the middle meningeal and occipital artery) in the territory of the left external carotid artery. A minimally invasive endovascular treatment was successfully performed. Conclusion: We present this case considering that only 100 patients with Cognard type V fistula have been reported to date. Additionally, we aim to highlight the importance of caution when administering corticosteroids in cases of diagnostic uncertainty. &lt;\/p&gt;<\/jats:p>","DOI":"10.1159\/000549322","type":"journal-article","created":{"date-parts":[[2025,11,3]],"date-time":"2025-11-03T17:01:55Z","timestamp":1762189315000},"page":"168-175","source":"Crossref","is-referenced-by-count":0,"title":["Extensive Brainstem Lesion and Cervical Myelopathy: Overcoming a Grim Prognosis \u2013 Case Report"],"prefix":"10.1159","volume":"17","author":[{"given":"Michaela","family":"Mencl","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Franti\u0161ek","family":"Charv\u00e1t","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Radek","family":"P\u00e1dr","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helena","family":"Hlav\u00e1\u010dov\u00e1","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kry\u0161tof","family":"Hlinka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julie","family":"Nov\u00e1kov\u00e1 Mart\u00ednkov\u00e1","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luk\u00e1\u0161","family":"Martinkovi\u010d","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ale\u0161","family":"Tomek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2025,10,31]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1007\/s10072-023-06870-1"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A2798"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1995.82.2.0166"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1161\/01.str.0000014772.02908.44"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.3171\/2009.7.JNS08490"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1002\/lary.20084"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-017-4946-5"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.194.3.7862961"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.3171\/2009.2.FOCUS0928"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2377-7-32"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.3389\/fneur.2020.526550"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2018.09.029"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.3171\/2014.11.JNS142278"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1136\/jnis.2009.001750"}],"container-title":["Case Reports in Neurology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000549322","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,10]],"date-time":"2025-12-10T09:12:24Z","timestamp":1765357944000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000549322"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10,31]]},"references-count":14,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2025,1,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000549322","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.30498425","asserted-by":"subject"}]},"ISSN":["1662-680X"],"issn-type":[{"type":"electronic","value":"1662-680X"}],"subject":[],"published":{"date-parts":[[2025,10,31]]}}}
