The authors report two paediatric cases with unusual presentation. Case 1: a 15-year-old girl was admitted following a period of fever, vomiting and left hypochondrium pain which became more localised to the left lower ribs. Blood tests suggested bacterial infection, but urinalysis and culture were negative. Renal CT scan presented features of bilateral pyelonephritis and left renal abscesses, while ultrasound remained normal until the ninth day of disease. Case 2: a 2-year-old girl, with diagnosis of \u03b2-thalassemia minor, had intermittent diffuse abdominal pain with 2\u2005weeks of evolution. Renal ultrasonography and CT scan showed a heterogeneous mass compatible with Willms tumour. Intraoperative diagnosis was compatible with renal abscess with isolation of <jats:italic>Proteus mirabilis<\/jats:italic> in the fluid. Both responded well to long-term antibiotics and to surgical drainage (in the second case).<\/jats:p>","DOI":"10.1136\/bcr-2013-202408","type":"journal-article","created":{"date-parts":[[2014,3,26]],"date-time":"2014-03-26T05:47:03Z","timestamp":1395812823000},"page":"bcr2013202408","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":8,"title":["Renal abscesses in childhood: report of two uncommon cases"],"prefix":"10.1136","volume":"2014","author":[{"given":"Candida","family":"Cancelinha","sequence":"first","affiliation":[{"name":"Department of Hospital Pedi\u00e1trico, Centro Hospitalar Universit\u00e1rio de Coimbra, Coimbra, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lea","family":"Santos","sequence":"additional","affiliation":[{"name":"Department of Hospital Pedi\u00e1trico, Centro Hospitalar Universit\u00e1rio de Coimbra, Coimbra, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carmen","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Department of Hospital Pedi\u00e1trico, Centro Hospitalar Universit\u00e1rio de Coimbra, Coimbra, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Clara","family":"Gomes","sequence":"additional","affiliation":[{"name":"Department of Hospital Pedi\u00e1trico, Centro Hospitalar Universit\u00e1rio de Coimbra, Coimbra, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2014,3,26]]},"reference":[{"key":"2025082701383989000_2014.mar26_1.bcr2013202408.1","first-page":"197","article-title":"Renal abscess in children: a clinical retrospective study","volume":"44","author":"Wang","year":"2003","journal-title":"Acta Paediatr Taiwan"},{"key":"2025082701383989000_2014.mar26_1.bcr2013202408.2","first-page":"167","article-title":"Perinephric abscess in pediatric patients: report of six cases and review of literature","volume":"8","author":"Edelstein","year":"1989","journal-title":"Pediat Infect Dis J"},{"key":"2025082701383989000_2014.mar26_1.bcr2013202408.3","doi-asserted-by":"publisher","DOI":"10.1007\/s00268-006-0162-x"},{"key":"2025082701383989000_2014.mar26_1.bcr2013202408.4","doi-asserted-by":"publisher","DOI":"10.1097\/INF.0b013e31817b617b"},{"key":"2025082701383989000_2014.mar26_1.bcr2013202408.5","doi-asserted-by":"publisher","DOI":"10.1007\/s00467-004-1646-2"},{"key":"2025082701383989000_2014.mar26_1.bcr2013202408.6","doi-asserted-by":"crossref","first-page":"341","DOI":"10.1590\/S0036-46652002000600009","article-title":"Perinephric and renal abscesses in children: a study of three cases","volume":"44","author":"Fernandes","year":"2002","journal-title":"Rev Inst Med Trop S Paulo"},{"key":"2025082701383989000_2014.mar26_1.bcr2013202408.7","doi-asserted-by":"publisher","DOI":"10.1007\/BF00878371"},{"key":"2025082701383989000_2014.mar26_1.bcr2013202408.8","doi-asserted-by":"publisher","DOI":"10.1097\/00006454-198403000-00013"},{"key":"2025082701383989000_2014.mar26_1.bcr2013202408.9","first-page":"1150","article-title":"Bilateral renal abscesses in a healthy child","volume":"4","author":"Laufer","year":"2002","journal-title":"Isr Med Assoc J"},{"key":"2025082701383989000_2014.mar26_1.bcr2013202408.10","doi-asserted-by":"publisher","DOI":"10.1097\/00006454-199106000-00006"},{"key":"2025082701383989000_2014.mar26_1.bcr2013202408.11","doi-asserted-by":"publisher","DOI":"10.1097\/INF.0b013e318204dcf3"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2013-202408","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T08:38:48Z","timestamp":1756283928000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2013-202408"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,3,26]]},"references-count":11,"alternative-id":["10.1136\/bcr-2013-202408"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2013-202408","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,3,26]]}}}
