A diagnosis of mediastinal teratoma with extension to the neck was made. Robot-assisted thymectomy was initiated but was complicated by dense tumor adherence to the superior vena cava and brachiocephalic veins, prompting a switch to a midline sternotomy. Simultaneous resection of the right thyroid lobe was performed due to inflammation. The transition to a midline sternotomy allowed successful excision of the tumor, which was confirmed to be a mature teratoma confined to the thoracic region. The patient's favorable postoperative course led to discharge on day 5 with no recurrence at nine months.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Emphasizing the challenges and the importance of prompt intervention in the management of mediastinal teratomas with neck extension.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s40792-024-01946-2","type":"journal-article","created":{"date-parts":[[2024,11,5]],"date-time":"2024-11-05T04:33:51Z","timestamp":1730781231000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A case of anterior mediastinal mature teratoma with severe inflammatory extension into the neck"],"prefix":"10.1186","volume":"10","author":[{"given":"Tomoki","family":"Keiya","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hirofumi","family":"Uehara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miho","family":"Aoyagi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atsushi","family":"Watanabe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,11,5]]},"reference":[{"key":"1946_CR1","doi-asserted-by":"publisher","first-page":"727","DOI":"10.1016\/S0022-5223(19)39090-7","volume":"86","author":"BD Lewis","year":"1983","unstructured":"Lewis BD, et al.
