We present a clinical case of a giant ectopic parathyroid adenoma (PA) in an unusual location, which brought significant diagnostical and therapeutical challenges. The tumour in the mediastinum was found incidentally on chest computed tomography (CT). A biopsy was conducted, and histological examination revealed a well-differentiated neuroendocrine tumour. The tumour was excised via right thoracotomy. The final histological examination revealed a parathyroid adenoma, which was unexpected for our team. After three years of observation, there is no evidence of tumour recurrence.<\/jats:p>","DOI":"10.3390\/medicina60101666","type":"journal-article","created":{"date-parts":[[2024,10,11]],"date-time":"2024-10-11T03:53:47Z","timestamp":1728618827000},"page":"1666","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Giant Parathyroid Adenoma of the Posterior Mediastinum"],"prefix":"10.3390","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-9426-0713","authenticated-orcid":false,"given":"Rokas","family":"Jagminas","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Vilnius University, LT-03225 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jolanta","family":"Jocien\u0117","sequence":"additional","affiliation":[{"name":"Clinic of Chest Disease, Immunology and Allergology, Institute of Clinical Medicine, Faculty of Medicine, Vilnius University, LT-03225 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9352-9135","authenticated-orcid":false,"given":"Vygant\u0117","family":"Maskoli\u016bnait\u0117","sequence":"additional","affiliation":[{"name":"Department of Pathology and Forensic Medicine, Institute of Biomedical Sciences, Faculty of Medicine, Vilnius University, LT-03225 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6344-8596","authenticated-orcid":false,"given":"\u017dymantas","family":"Jagelavi\u010dius","sequence":"additional","affiliation":[{"name":"Clinic of Chest Disease, Immunology and Allergology, Institute of Clinical Medicine, Faculty of Medicine, Vilnius University, LT-03225 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"63","DOI":"10.1007\/s00423-019-01751-8","article-title":"The prevalence and anatomy of parathyroid glands: A meta-analysis with implications for parathyroid surgery","volume":"404","author":"Taterra","year":"2019","journal-title":"Langenbeck\u2019s Arch.
