Posterior reversible encephalopathy syndrome (PRES) in kidney transplant recipients is commonly attributed to calcineurin inhibitor (CNI) toxicity; however, the biochemical signatures of CNI toxicity and TRAS differ markedly. Case Presentation: We report a 32-year-old woman, 5 months post-transplant, presenting with seizures, severe hypertension, and MRI-confirmed PRES. She exhibited hypokalaemia (2.6 mmol\/L) and metabolic alkalosis (pH 7.50, bicarbonate 34 mmol\/L) \u2013 findings less typical of tacrolimus toxicity, which more typically produces a Gordon-like physiology with hyperkalaemia and metabolic acidosis due to excess activity of the NCC (Na-Cl cotransporter). Doppler ultrasound and digital subtraction angiography confirmed TRAS. Percutaneous angioplasty resulted in rapid renal recovery. Conclusion: PRES with hypokalaemia should prompt evaluation for renovascular hypertension rather than tacrolimus toxicity.<\/jats:p>","DOI":"10.1159\/000552595","type":"journal-article","created":{"date-parts":[[2026,5,19]],"date-time":"2026-05-19T16:00:45Z","timestamp":1779206445000},"page":"100-105","source":"Crossref","is-referenced-by-count":0,"title":["Transplant Renal Artery Stenosis Presenting as Posterior Reversible Encephalopathy Syndrome in a Post-Kidney Transplant Patient: A Case Report"],"prefix":"10.1159","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6099-2329","authenticated-orcid":false,"given":"Mihiran","family":"Thanigasalan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thivacaren","family":"Sritharan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4876-3632","authenticated-orcid":false,"given":"Mehatheepan","family":"Rasanayagam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anura Priyantha","family":"Hewageegana","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2026,5,19]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.4236\/ojneph.2024.142025"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097\/01.asn.0000099379.61001.f8"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199602223340803"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A0928"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1097\/01.tp.0000889576.52364.48"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1038\/nm.2497"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.3390\/ijms20133210"}],"container-title":["Case Reports in Nephrology and Dialysis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000552595","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,10]],"date-time":"2026-07-10T16:01:06Z","timestamp":1783699266000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000552595"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,5,19]]},"references-count":7,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026,1,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000552595","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.32325030","asserted-by":"subject"}]},"ISSN":["2296-9705"],"issn-type":[{"value":"2296-9705","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,5,19]]}}}
