The radiographic features were non-specific. However, the similar CT characteristics of both lesions and background history raised the suspicion of a synchronous mesenchymal tumor, and histopathology confirmed the diagnosis. The rarity of these tumors in the pediatric population and lack of specific diagnostic criteria impose reporting the case and emphasize the need for further research on imaging features of such tumors. <\/jats:p>","DOI":"10.1259\/bjrcr.20220105","type":"journal-article","created":{"date-parts":[[2022,11,21]],"date-time":"2022-11-21T13:01:02Z","timestamp":1669035662000},"source":"Crossref","is-referenced-by-count":1,"title":["Renal and mediastinal perivascular epithelioid cell tumors (PEComas) in a young child with tuberous sclerosis; a rare case report"],"prefix":"10.1093","volume":"9","author":[{"given":"Kamal H.","family":"Attia","sequence":"first","affiliation":[{"name":"Department of Radiology and Medical Imaging, King Saud university medical city, Riyadh, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmad A.","family":"Al Boukai","sequence":"additional","affiliation":[{"name":"Department of Radiology and Medical Imaging, King Saud university medical city, Riyadh, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muammar H.","family":"Mohammed","sequence":"additional","affiliation":[{"name":"Department of Radiology and Medical Imaging, King Saud university medical city, Riyadh, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maha","family":"Arafah","sequence":"additional","affiliation":[{"name":"Department of Pathology, King Saud University, Riyadh, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","reference":[{"doi-asserted-by":"publisher","key":"b1","DOI":"10.1007\/s00428-007-0509-1"},{"doi-asserted-by":"publisher","key":"b2","DOI":"10.1111\/j.1365-2559.2005.02316.x"},{"doi-asserted-by":"publisher","key":"b3","DOI":"10.2214\/AJR.13.10909"},{"doi-asserted-by":"publisher","key":"b4","DOI":"10.1002\/ijc.27800"},{"doi-asserted-by":"publisher","key":"b5","DOI":"10.1038\/nrdp.2016.35"},{"doi-asserted-by":"publisher","key":"b6","DOI":"10.15761\/CCRR.1000158"},{"doi-asserted-by":"publisher","key":"b7","DOI":"10.1016\/j.crad.2012.10.021"},{"key":"b8","first-page":"415","volume":"38","author":"Mai KT","year":"2006","journal-title":"Pathology"},{"doi-asserted-by":"publisher","key":"b9","DOI":"10.1097\/01.pas.0000173232.22117.37"}],"container-title":["BJR|case reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.birpublications.org\/doi\/pdf\/10.1259\/bjrcr.20220105","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,1,12]],"date-time":"2024-01-12T15:51:52Z","timestamp":1705074712000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/bjrcr\/article\/7279122"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,3]]},"references-count":9,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2023,3]]}},"alternative-id":["10.1259\/bjrcr.20220105"],"URL":"https:\/\/doi.org\/10.1259\/bjrcr.20220105","relation":{},"ISSN":["2055-7159"],"issn-type":[{"type":"electronic","value":"2055-7159"}],"subject":[],"published":{"date-parts":[[2023,3]]},"article-number":"20220105"}}
