The first step in identifying its etiology is to determine the serum-ascites albumin gradient (SAAG). According to this parameter, a high SAAG is regarded as a gradient greater than 1.1 g\/dL. This condition has some differential diagnoses such as liver cirrhosis, Budd-Chiari syndrome, heart failure, and idiopathic portal fibrosis.  In the present article, we present a young man with abdominal distention due to a high SAAG. Further evaluation of the abdominal and thoracic cavity revealed a mass in the posterior mediastinum, which had compressed the inferior vena cava and left atrium and led to Budd-Chiari syndrome. Evaluation of the biopsy sample showed fibrosarcoma.  Mediastinal fibrosarcomas, though rare, should be considered in the differential diagnosis of mediastinal masses.<\/jats:p>","DOI":"10.15171\/mejdd.2018.120","type":"journal-article","created":{"date-parts":[[2018,12,6]],"date-time":"2018-12-06T12:47:19Z","timestamp":1544100439000},"page":"258-262","update-policy":"http:\/\/dx.doi.org\/10.15171\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A High Serum-Ascites Albumin Gradient and Mediastinal Fibrosarcoma: A Case Report"],"prefix":"10.34172","volume":"10","author":[{"given":"Ahmad","family":"Hormati","sequence":"first","affiliation":[{"name":"Assistant Professor of Gastroenterology, Research Center for Gastroenterology and Hepatology, Qom University of Medical Sciences, Qom, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maryam","family":"Jameshorani","sequence":"additional","affiliation":[{"name":"Assistant Professor of Internal Medicine, Metabolic Disease Research Center, Zanjan University of Medical Sciences, Zanjan, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saeid","family":"Sarkeshikian","sequence":"additional","affiliation":[{"name":"Assistant Professor of Gastroenterology, Research Center for Gastroenterology and Hepatology, Qom University of Medical Sciences, Qom, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammad Reza","family":"Ghadir","sequence":"additional","affiliation":[{"name":"Associate Professor of Gastroenterology, Research Center for Gastroenterology and Hepatology, Qom University of Medical Sciences, Qom, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Faezeh","family":"Alemi","sequence":"additional","affiliation":[{"name":"General Practitioner, Research Center for Gastroenterology and Hepatology, Qom University of Medical Sciences, Qom, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"20123","published-online":{"date-parts":[[2018,9,7]]},"reference":[{"key":"R1","unstructured":"Runyon BA.
