The obstruction can occur either due to tumour invasion of the vessel wall with associated thrombus or due to vessel wall compression by the tumour mass. The patient being reported is a young male who presented with recurrent episodes of syncope and was found to have mediastinal Gardner fibroma causing SVC syndrome. Gardner fibroma is a benign soft tissue lesion; and its occurrence in the mediastinum resulting in SVC syndrome has not been reported yet.<\/jats:p>","DOI":"10.1136\/bcr-2019-232433","type":"journal-article","created":{"date-parts":[[2019,12,5]],"date-time":"2019-12-05T04:55:14Z","timestamp":1575521714000},"page":"e232433","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Superior vena cava syndrome due to mediastinal Gardner fibroma presenting as syncope"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3973-6800","authenticated-orcid":false,"given":"Robin George","family":"Manappallil","sequence":"first","affiliation":[{"name":"Internal Medicine, Baby Memorial Hospital, Calicut, Kerala, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harilal","family":"Nambiar","sequence":"additional","affiliation":[{"name":"Cardiothoracic and Vascular Surgery, Baby Memorial Hospital, Calicut, Kerala, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neena","family":"Mampilly","sequence":"additional","affiliation":[{"name":"Pathology, Baby Memorial Hospital, Calicut, Kerala, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Della","family":"Harigovind","sequence":"additional","affiliation":[{"name":"Radio-diagnosis and Imaging, Baby Memorial Hospital, Calicut, Kerala, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,12,4]]},"reference":[{"key":"2025082723460044000_12.12.e232433.1","first-page":"323","article-title":"The history of an aneurysm of the aorta with some remarks on aneurysms in general","volume":"1","author":"Hunter","year":"1757","journal-title":"Med Obs Enq"},{"key":"2025082723460044000_12.12.e232433.2","first-page":"61","article-title":"Causes and management of superior vena cava syndrome","volume":"7","author":"Escalante","year":"1993","journal-title":"Oncology"},{"key":"2025082723460044000_12.12.e232433.3","unstructured":"Gucalp R , Dutcher JP .
