Bilateral cystic nephromas are even rarer with only a handful cases reported in the literature. A case of a 2-year-old male child who presented with bilateral renal cystic masses later diagnosed as cystic nephromas is presented here. Ultrasound, CT scan and histopathological investigations aided in arriving at the correct diagnosis. The most concerning feature was the presence of a fluid filled cystic mass in the lungs, most probably a pleuropulmonary blastoma which is a rare malignant neoplasm known to be associated with bilateral cystic nephromas. The most common presenting symptoms of cystic nephroma are painless abdominal mass, abdominal or flank pain and haematuria. These tumours usually follow a benign course and nephrectomy alone is curative. A close surveillance of such patients is recommended because of elevated risk of other tumours.<\/jats:p>","DOI":"10.1136\/bcr.05.2011.4171","type":"journal-article","created":{"date-parts":[[2011,8,18]],"date-time":"2011-08-18T14:04:05Z","timestamp":1313676245000},"page":"bcr0520114171","source":"Crossref","is-referenced-by-count":8,"title":["Bilateral cystic nephroma with pleuropulmonary blastoma"],"prefix":"10.1136","volume":"2011","author":[{"given":"Anand Kumar","family":"Bhardwaj","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Prem Dass","family":"Sharma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amit","family":"Mittal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akshay","family":"Sharma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2011,8,18]]},"reference":[{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.1","doi-asserted-by":"publisher","DOI":"10.1259\/bjr\/62643156"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.2","doi-asserted-by":"publisher","DOI":"10.1007\/s003830050290"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.3","doi-asserted-by":"publisher","DOI":"10.1007\/s00383-005-1544-0"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.4","doi-asserted-by":"publisher","DOI":"10.1007\/s00467-010-1528-8"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.5","doi-asserted-by":"crossref","first-page":"1358","DOI":"10.1016\/S0022-5347(17)35258-8","article-title":"Partial nephrectomy in a metachronous multilocular cyst of the kidney (cystic nephroma).","volume":"151","author":"Ferrer","year":"1994","journal-title":"J Urol"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.6","doi-asserted-by":"publisher","DOI":"10.1067\/msy.2003.57"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.7","doi-asserted-by":"publisher","DOI":"10.1002\/ppul.20917"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.8","first-page":"89","article-title":"Cystic adenoma of the kidney","volume":"43","author":"Edmunds","year":"1892","journal-title":"Trans Pathol Soc Lond"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.9","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.1951.tb02576.x"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.10","doi-asserted-by":"crossref","first-page":"530","DOI":"10.1016\/S0022-5347(17)66732-6","article-title":"Benign multilocular cystic nephroma: report of two cases of so-called multilocular cyst of the kidney.","volume":"76","author":"Boggs","year":"1956","journal-title":"J Urol"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.11","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19890715)64:2<466::AID-CNCR2820640221>3.0.CO;2-V"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.12","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5347(05)67562-3"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.13","doi-asserted-by":"publisher","DOI":"10.1016\/S0090-4295(98)00386-0"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.14","doi-asserted-by":"crossref","first-page":"1391","DOI":"10.1016\/S0033-8389(22)00732-1","article-title":"Renal neoplasms of childhood.","volume":"35","author":"Geller","year":"1997","journal-title":"Radiol Clin North Am"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.15","doi-asserted-by":"publisher","DOI":"10.1148\/rg.242035070"},{"key":"2025042708001994000_2011.aug17_1.bcr0520114171.16","doi-asserted-by":"crossref","first-page":"653","DOI":"10.1148\/radiographics.15.3.7624570","article-title":"Multilocular cystic renal tumor in children: radiologic-pathologic correlation.","volume":"15","author":"Agrons","year":"1995","journal-title":"Radiographics"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr.05.2011.4171","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T15:00:27Z","timestamp":1745766027000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr.05.2011.4171"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,8,18]]},"references-count":16,"alternative-id":["10.1136\/bcr.05.2011.4171"],"URL":"https:\/\/doi.org\/10.1136\/bcr.05.2011.4171","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2011,8,18]]}}}
