They present most frequently in cases of superior vena cava (SVC) obstruction and are related to the recruitment of the cavo-mammary-phrenic\u2013hepatic\u2013capsule\u2013portal and the cavo-superficial\u2013umbilical\u2013portal pathways. We present the case of a 52-year-old female patient with an highly aggressive retroperitoneal liposarcoma with SVC obstruction caused by external compression due to a mediastinal metastatic mass. The patient exhibited no symptoms of SVC obstruction due to the collateral cavo-portal pathways.<\/jats:p>","DOI":"10.1136\/bcr-2020-237317","type":"journal-article","created":{"date-parts":[[2021,1,12]],"date-time":"2021-01-12T14:01:15Z","timestamp":1610460075000},"page":"e237317","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Changes
