We describe a 59\u2010year\u2010old man who presented with transient right\u2010sided weakness and facial droop following new\u2010onset seizures. CT demonstrated asymmetric arterial\u2010phase enhancement of the left transverse sinus and cortical veins, while MRI revealed left occipitotemporal and cerebellar hemorrhages consistent with venous congestion. Digital subtraction angiography confirmed a high\u2010grade left anterior condylar iDAVF with cortical venous reflux (Borden II; Cognard IIa+b). Endovascular embolization was unsuccessful because of challenging vascular anatomy. Definitive management was achieved through surgical disconnection and targeted sinus coiling. This case highlights the diverse presentations of iDAVFs and emphasizes the importance of considering a vascular etiology in patients with atypical stroke\u2010like or postictal deficits.<\/jats:p>","DOI":"10.1002\/ccr3.73102","type":"journal-article","created":{"date-parts":[[2026,7,7]],"date-time":"2026-07-07T04:14:47Z","timestamp":1783397687000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Stroke\u2010Mimic: An Intracranial Dural Arteriovenous Fistula Revealed by New\u2010Onset Seizures and Post\u2010Ictal Deficit"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0170-2170","authenticated-orcid":false,"given":"Michael","family":"Van Haute","sequence":"first","affiliation":[{"name":"Stroke Unit Naas General Hospital  Naas, Co.
