His medical history was significant for metastatic renal cell carcinoma treated 5\u2005years previously with cytoreductive nephrectomy and adjuvant chemotherapy. Following an abnormal chest radiograph showing an ill-defined right paratracheal mass, a CT scan showed eggshell calcification (circumferential calcification) of enlarged low right paratracheal lymph nodes. An endobronchial ultrasound\u2013guided transbronchial needle aspiration of an involved large paratracheal lymph node showed cytology consistent with metastatic renal cell carcinoma.<\/jats:p>","DOI":"10.1136\/bcr-2014-209202","type":"journal-article","created":{"date-parts":[[2015,4,28]],"date-time":"2015-04-28T07:16:08Z","timestamp":1430205368000},"page":"bcr2014209202","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Metastatic renal cell carcinoma presenting with mediastinal eggshell calcification"],"prefix":"10.1136","volume":"2015","author":[{"given":"Jacob S","family":"Heng","sequence":"first","affiliation":[{"name":"Imperial College London, London, UK"},{"name":"Department of Rheumatology and General Medicine, Northwick Park Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abeer S","family":"Ghuman","sequence":"additional","affiliation":[{"name":"Department of Rheumatology and General Medicine, Northwick Park Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shahir S","family":"Hamdulay","sequence":"additional","affiliation":[{"name":"Department of Rheumatology and General Medicine, Northwick Park Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hassan","family":"Hirji","sequence":"additional","affiliation":[{"name":"Department of Radiology, Northwick Park Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,4,28]]},"reference":[{"key":"2025082722052158000_2015.apr28_1.bcr2014209202.1","doi-asserted-by":"publisher","DOI":"10.1016\/0037-198X(67)90015-6"},{"key":"2025082722052158000_2015.apr28_1.bcr2014209202.2","doi-asserted-by":"publisher","DOI":"10.1148\/119.3.554"},{"key":"2025082722052158000_2015.apr28_1.bcr2014209202.3","doi-asserted-by":"publisher","DOI":"10.3109\/02841867709133951"},{"key":"2025082722052158000_2015.apr28_1.bcr2014209202.4","doi-asserted-by":"publisher","DOI":"10.1016\/S0009-9260(96)80343-6"},{"key":"2025082722052158000_2015.apr28_1.bcr2014209202.5","doi-asserted-by":"publisher","DOI":"10.1378\/chest.66.5.515"},{"key":"2025082722052158000_2015.apr28_1.bcr2014209202.6","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.135.6.1265"},{"key":"2025082722052158000_2015.apr28_1.bcr2014209202.7","unstructured":"Felson B .
