The \u201cvasogenic theory\u201d suggests that, in this condition, disrupted cerebrovascular autoregulation leads to blood\u2010brain barrier failure and vasogenic edema. Posterior reversible encephalopathy syndrome is commonly associated with hypertension, chemotherapy, and transplantation, but neurosurgical patients, including those undergoing digital subtraction angiography, are also at elevated risk. A patient with a history of traumatic brain injury underwent surveillance digital subtraction angiography for a clipped pseudoaneurysm. Periprocedurally, the patient developed left gaze deviation, right hemiplegia, seizures, and magnetic resonance imaging findings consistent with posterior reversible encephalopathy syndrome. The diagnosis relied on distinct radiographic features, normal laboratory results, electroencephalography consistent with encephalopathy, no evidence of infection, a history of traumatic brain injury, and spontaneous clinical improvement. Posterior reversible encephalopathy syndrome can be triggered by cerebral blood flow changes or cytotoxic endothelial damage, particularly in individuals with compromised blood\u2010brain barrier integrity. Awareness of risk factors, pathophysiology, and clinical and radiographic patterns is crucial for accurate diagnosis.<\/jats:p>","DOI":"10.1161\/svin.124.001362","type":"journal-article","created":{"date-parts":[[2025,3,12]],"date-time":"2025-03-12T11:50:24Z","timestamp":1741780224000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Pressurized Contrast\u2010Related Posterior Reversible Encephalopathy Syndrome After Cerebral Digital Subtraction Angiography"],"prefix":"10.1161","volume":"5","author":[{"given":"Lea","family":"Scherschinski","sequence":"first","affiliation":[{"name":"St. Joseph's Hospital and Medical Center","place":["Phoenix"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tyler D.","family":"Schriber","sequence":"additional","affiliation":[{"name":"St. Joseph's Hospital and Medical Center","place":["Phoenix"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan W.","family":"Koester","sequence":"additional","affiliation":[{"name":"St. Joseph's Hospital and Medical Center","place":["Phoenix"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adam T.","family":"Eberle","sequence":"additional","affiliation":[{"name":"St. Joseph's Hospital and Medical Center","place":["Phoenix"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joshua S.","family":"Catapano","sequence":"additional","affiliation":[{"name":"St. Joseph's Hospital and Medical Center","place":["Phoenix"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ethan A.","family":"Winkler","sequence":"additional","affiliation":[{"name":"St. Joseph's Hospital and Medical Center","place":["Phoenix"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Felipe C.","family":"Albuquerque","sequence":"additional","affiliation":[{"name":"St. Joseph's Hospital and Medical Center","place":["Phoenix"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael T.","family":"Lawton","sequence":"additional","affiliation":[{"name":"St. Joseph's Hospital and Medical Center","place":["Phoenix"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew F.","family":"Ducruet","sequence":"additional","affiliation":[{"name":"St. Joseph's Hospital and Medical Center","place":["Phoenix"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruchira M.","family":"Jha","sequence":"additional","affiliation":[{"name":"St. Joseph's Hospital and Medical Center","place":["Phoenix"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9454-0678","authenticated-orcid":false,"given":"Ashutosh P.","family":"Jadhav","sequence":"additional","affiliation":[{"name":"St. Joseph's Hospital and Medical Center","place":["Phoenix"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(15)00111-8"},{"issue":"1","key":"e_1_3_2_3_2","doi-asserted-by":"crossref","first-page":"45","DOI":"10.1016\/j.diii.2012.02.005","article-title":"Posterior reversible encephalopathy syndrome (PRES): features on CT and MR imaging","volume":"94","author":"Hugonnet E","year":"2013","unstructured":"Hugonnet E, Da Ines D, Boby H, Claise B, Petitcolin V, Lannareix V, Garcier JM.
