MRI revealed a large well-defined T1 and T2 hypointense mildly enhancing lesion in the right anterior pararenal space displacing the right kidney and encasing the right ureter with T2 hyperintense wall thickening of the left renal pelvis and ureter. A provisional diagnosis of solitary fibrous tumour was kept. Bilateral double J stenting was done for hydronephrosis. Surgical debulking of the lesion was done with biopsy from the left periureteral wall thickening and was found to be myelolipoma on histopathological examination. This case is a novel variety of myelolipoma which is lipid poor, extra-adrenal and in bilateral perirenal and periureteric location.<\/jats:p>","DOI":"10.1136\/bcr-2017-221846","type":"journal-article","created":{"date-parts":[[2017,10,9]],"date-time":"2017-10-09T09:11:24Z","timestamp":1507540284000},"page":"bcr-2017-221846","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["A rare case of extra-adrenal bilateral perirenal and periureteric myelolipoma"],"prefix":"10.1136","volume":"2017","author":[{"given":"Samireddypalle","family":"Yugandhar","sequence":"first","affiliation":[{"name":"Department of Radiology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanjoy Kumar","family":"Sureka","sequence":"additional","affiliation":[{"name":"Department of Urology and Renal Transplant, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Priyank","family":"Yadav","sequence":"additional","affiliation":[{"name":"Department of Urology and Renal Transplant, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hira","family":"Lal","sequence":"additional","affiliation":[{"name":"Department of Radiology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2017,10,9]]},"reference":[{"key":"2025082701465476000_2017.oct07_1.bcr-2017-221846.1","first-page":"665","article-title":"Adrenal myelolipoma","volume":"73","author":"Olsson","year":"1973","journal-title":"Surgery"},{"key":"2025082701465476000_2017.oct07_1.bcr-2017-221846.2","doi-asserted-by":"crossref","first-page":"279","DOI":"10.12998\/wjcc.v2.i7.279","article-title":"Perirenal extra-adrenal myelolipoma","volume":"2","author":"Hajiran","year":"2014","journal-title":"World J Clin Cases"},{"key":"2025082701465476000_2017.oct07_1.bcr-2017-221846.3","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.17.6.9397452"},{"key":"2025082701465476000_2017.oct07_1.bcr-2017-221846.4","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.183.3.1830833"},{"key":"2025082701465476000_2017.oct07_1.bcr-2017-221846.5","doi-asserted-by":"publisher","DOI":"10.1148\/rg.323115020"},{"key":"2025082701465476000_2017.oct07_1.bcr-2017-221846.6","doi-asserted-by":"crossref","first-page":"204","DOI":"10.1016\/j.diii.2011.12.010","article-title":"Retroperitoneal extra-adrenal myelolipoma: appearance in CT and MRI","volume":"93","author":"Butori","year":"2012","journal-title":"Diagn Interv Imaging"},{"key":"2025082701465476000_2017.oct07_1.bcr-2017-221846.7","doi-asserted-by":"publisher","DOI":"10.1002\/dc.23178"},{"key":"2025082701465476000_2017.oct07_1.bcr-2017-221846.8","doi-asserted-by":"publisher","DOI":"10.1259\/bjr\/28801968"},{"key":"2025082701465476000_2017.oct07_1.bcr-2017-221846.9","doi-asserted-by":"crossref","first-page":"1049","DOI":"10.5858\/2006-130-1049-EMITRH","article-title":"Extra-adrenal myelolipoma in the renal hilum: a case report and review of the literature","volume":"130","author":"Talwalkar","year":"2006","journal-title":"Arch Pathol Lab Med"},{"key":"2025082701465476000_2017.oct07_1.bcr-2017-221846.10","doi-asserted-by":"crossref","first-page":"164","DOI":"10.5489\/cuaj.971","article-title":"Bilateral renal sinus myelolipomas","volume":"4","author":"Cox","year":"2010","journal-title":"Can Urol Assoc J"},{"key":"2025082701465476000_2017.oct07_1.bcr-2017-221846.11","doi-asserted-by":"crossref","first-page":"317","DOI":"10.1016\/S1000-1948(11)60019-1","article-title":"Myelolipoma of the kidney: a seldom site for a rare extra-adrenal tumor","volume":"25","author":"Xuefeng","year":"2010","journal-title":"Journal of Medical Colleges of PLA"},{"key":"2025082701465476000_2017.oct07_1.bcr-2017-221846.12","first-page":"1","article-title":"Extra-adrenal myelolipoma presenting as efferent limb obstruction","volume":"2012","author":"Conley","year":"2012","journal-title":"Case Rep Surg"},{"key":"2025082701465476000_2017.oct07_1.bcr-2017-221846.13","doi-asserted-by":"crossref","first-page":"631","DOI":"10.5858\/1999-123-0631-MOTRS","article-title":"Myelolipoma of the renal sinus.
