Their opportunistic nature and tendency to develop antibiotic resistance make Citrobacter species challenging to treat. Renal or perinephric abscess formation as a result of Citrobacter infection is uncommon, having only previously been reported in four cases. We present a case of a 70-year-old man with diabetes and prostate cancer who was diagnosed with an 18\u2009cm perinephric and a 10\u2009cm perihepatic abscess caused by Citrobacter koseri. The patient required drains and re-positioning of the drains multiple times in addition to a prolonged course of antibiotics to achieve complete radiographic resolution. This case highlights the challenges in treating renal and perinephric abscess, as it required drain re-placements two additional times after the initial placement and an additional 4\u2009weeks of antibiotics. Successful treatment for larger abscesses usually requires a two-arm approach, with antibiotics in combination with either percutaneous or surgical abscess drainage. <\/jats:p>","DOI":"10.1177\/2050313x221135347","type":"journal-article","created":{"date-parts":[[2022,11,1]],"date-time":"2022-11-01T11:23:27Z","timestamp":1667301807000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["A case of <i>Citrobacter koseri<\/i> renal abscess and review of the literature"],"prefix":"10.1177","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7636-751X","authenticated-orcid":false,"given":"Duong Tommy","family":"Hua","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Harbor-UCLA Medical Center, Torrance, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica","family":"Lo","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Harbor-UCLA Medical Center, Torrance, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huy Quang","family":"Do","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Harbor-UCLA Medical Center, Torrance, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles Dac","family":"Pham","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Harbor-UCLA Medical Center, Torrance, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2022,11,1]]},"reference":[{"key":"bibr1-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1128\/9781555817381"},{"key":"bibr2-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2014-204095"},{"key":"bibr3-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1016\/j.jinf.2006.01.015"},{"key":"bibr4-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1007\/s10096-008-0598-z"},{"key":"bibr5-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.2169\/internalmedicine.50.4962"},{"key":"bibr6-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajic.2003.07.009"},{"key":"bibr7-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1017\/S0950268816001102"},{"key":"bibr8-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1016\/j.idcr.2021.e01159"},{"key":"bibr9-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1093\/clinids\/16.Supplement_4.S299"},{"key":"bibr10-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1016\/0163-4453(93)93058-C"},{"key":"bibr11-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1159\/000109725"},{"key":"bibr12-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1016\/S0090-4295(74)80168-8"},{"key":"bibr13-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1016\/j.eucr.2016.11.013"},{"issue":"4","key":"bibr14-2050313X221135347","first-page":"642","volume":"6","author":"Khanna A","year":"2012","journal-title":"J Clin Diagn Res"},{"key":"bibr15-2050313X221135347","first-page":"23","volume":"4","author":"Sami H","year":"2017","journal-title":"J Health Res"},{"key":"bibr16-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.3947\/ic.2019.51.1.1"},{"key":"bibr17-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.3349\/ymj.2010.51.4.569"},{"key":"bibr18-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5347(01)66536-4"},{"key":"bibr19-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.155.1.2112870"},{"key":"bibr20-2050313X221135347","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-6757(99)90060-8"}],"container-title":["SAGE Open Medical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X221135347","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/2050313X221135347","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X221135347","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,3]],"date-time":"2025-03-03T11:57:48Z","timestamp":1741003068000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/2050313X221135347"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,1]]},"references-count":20,"alternative-id":["10.1177\/2050313X221135347"],"URL":"https:\/\/doi.org\/10.1177\/2050313x221135347","relation":{},"ISSN":["2050-313X","2050-313X"],"issn-type":[{"value":"2050-313X","type":"print"},{"value":"2050-313X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,1]]},"article-number":"2050313X221135347"}}
