Although it is reported to be safe and effective, immune dysregulation leading to autoimmunity has become an area of concern. Retroperitoneal fibrosis (RPF) is an immune\u2010mediated fibroinflammatory disease characterized by the deposition of fibrous tissues, primarily around the abdominal aorta and iliac arteries. Herein, we report a case of RPF following Pfizer BioNTech COVID\u201019 mRNA vaccination. To the best of our knowledge, there have been no published reports on RPF after COVID\u201019 mRNA vaccination. A 58\u2010year\u2010old woman with no history of autoimmune diseases presented with acute onset of epigastric pain 5\u2009weeks after the second dose of the Pfizer\u2010BioNTech vaccine. She had been diagnosed with stage I breast cancer 9\u2009years ago and was in complete remission on admission. Abdominal computed tomography showed preaortic soft\u2010tissue infiltration around the origin of the superior mesenteric artery but no evidence of breast cancer recurrence. Considering the temporal relationship between current symptoms and vaccination and the absence of other possible causes, she was diagnosed with RPF secondary to Pfizer\u2010BioNTech vaccine\u2010induced autoimmunity. This case may raise awareness of the possibility of RPF development following COVID\u201019 mRNA vaccination.<\/jats:p>","DOI":"10.1111\/1756-185x.14621","type":"journal-article","created":{"date-parts":[[2023,2,23]],"date-time":"2023-02-23T06:34:18Z","timestamp":1677134058000},"page":"1368-1372","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["New\u2010onset retroperitoneal fibrosis following COVID\u201019 mRNA vaccination: Coincidental or vaccine\u2010induced phenomenon?"],"prefix":"10.1111","volume":"26","author":[{"given":"Hirut Yadeta","family":"Ture","sequence":"first","affiliation":[{"name":"Division of Rheumatology, Department of Internal Medicine Kyungpook National University School of Medicine  Daegu South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Na Ri","family":"Kim","sequence":"additional","affiliation":[{"name":"Division of Rheumatology, Department of Internal Medicine Kyungpook National University School of Medicine  Daegu South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2671-6392","authenticated-orcid":false,"given":"Eon Jeong","family":"Nam","sequence":"additional","affiliation":[{"name":"Division of Rheumatology, Department of Internal Medicine Kyungpook National University School of Medicine  Daegu South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,2,22]]},"reference":[{"doi-asserted-by":"publisher","key":"e_1_2_7_2_1","DOI":"10.1111\/imm.13443"},{"doi-asserted-by":"publisher","key":"e_1_2_7_3_1","DOI":"10.1056\/NEJMoa2110345"},{"doi-asserted-by":"publisher","key":"e_1_2_7_4_1","DOI":"10.1016\/j.clim.2020.108480"},{"doi-asserted-by":"publisher","key":"e_1_2_7_5_1","DOI":"10.1007\/s10067-022-06126-x"},{"doi-asserted-by":"publisher","key":"e_1_2_7_6_1","DOI":"10.1016\/j.intimp.2021.107970"},{"doi-asserted-by":"publisher","key":"e_1_2_7_7_1","DOI":"10.1016\/j.clim.2020.108426"},{"doi-asserted-by":"publisher","key":"e_1_2_7_8_1","DOI":"10.1007\/s11926-018-0789-2"},{"doi-asserted-by":"publisher","key":"e_1_2_7_9_1","DOI":"10.1681\/ASN.2015101110"},{"doi-asserted-by":"publisher","key":"e_1_2_7_10_1","DOI":"10.1002\/art.41024"},{"doi-asserted-by":"publisher","key":"e_1_2_7_11_1","DOI":"10.1080\/14740338.2020.1766022"},{"doi-asserted-by":"publisher","key":"e_1_2_7_12_1","DOI":"10.1007\/s12094-018-1936-y"},{"doi-asserted-by":"publisher","key":"e_1_2_7_13_1","DOI":"10.4103\/0366-6999.201606"},{"doi-asserted-by":"publisher","key":"e_1_2_7_14_1","DOI":"10.1016\/j.jhep.2021.06.044"},{"doi-asserted-by":"publisher","key":"e_1_2_7_15_1","DOI":"10.1016\/0002-8703(83)90412-X"},{"doi-asserted-by":"publisher","key":"e_1_2_7_16_1","DOI":"10.1016\/j.amsu.2022.103590"},{"doi-asserted-by":"publisher","key":"e_1_2_7_17_1","DOI":"10.1016\/j.jhep.2021.02.006"},{"doi-asserted-by":"publisher","key":"e_1_2_7_18_1","DOI":"10.1093\/rheumatology\/kez667"},{"doi-asserted-by":"publisher","key":"e_1_2_7_19_1","DOI":"10.1038\/s41584-020-0372-x"},{"doi-asserted-by":"publisher","key":"e_1_2_7_20_1","DOI":"10.1016\/S0140-6736(11)60934-3"}],"container-title":["International Journal of Rheumatic Diseases"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1756-185X.14621","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/1756-185X.14621","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1756-185X.14621","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,18]],"date-time":"2023-08-18T05:33:36Z","timestamp":1692336816000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/1756-185X.14621"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,2,22]]},"references-count":19,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2023,7]]}},"alternative-id":["10.1111\/1756-185X.14621"],"URL":"https:\/\/doi.org\/10.1111\/1756-185x.14621","archive":["Portico"],"relation":{},"ISSN":["1756-1841","1756-185X"],"issn-type":[{"type":"print","value":"1756-1841"},{"type":"electronic","value":"1756-185X"}],"subject":[],"published":{"date-parts":[[2023,2,22]]},"assertion":[{"value":"2023-01-01","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-02-07","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-02-22","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
