They may be associated with autoimmune diseases, such as rheumatoid arthritis and systemic sclerosis. Methods: a 61-year-old man with a history of rheumatoid arthritis for 8 years was referred to our unit because of a multiloculated mass in the anterior mediastinum with a high F18\u2009fluorodeoxyglucose uptake at PET-CT scan. Histology showed a multilocular thymic cyst with lymphoid tissue, organized in germinal centers and internodal areas. Results: rheumatoid arthritis-related symptoms progressively disappeared after the excision of the mass. Conclusions: to our knowledge, this is the first report in the English language of rheumatoid arthritis symptoms improvement after multilocular thymic cyst surgical removal.<\/jats:p>","DOI":"10.3390\/jcm14020620","type":"journal-article","created":{"date-parts":[[2025,1,20]],"date-time":"2025-01-20T12:32:52Z","timestamp":1737376372000},"page":"620","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Multilocular Thymic Cyst with High F18\u2009Fluorodeoxyglucose Uptake and Rheumatoid Arthritis: A Case Report"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1580-6379","authenticated-orcid":false,"given":"Francesco","family":"Ferrante","sequence":"first","affiliation":[{"name":"Division of Thoracic Surgery, Policlinico Umberto I, Sapienza University of Rome, 00165 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Camilla","family":"Poggi","sequence":"additional","affiliation":[{"name":"Division of Thoracic Surgery, Policlinico Umberto I, Sapienza University of Rome, 00165 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anastasia","family":"Centofanti","sequence":"additional","affiliation":[{"name":"Division of Thoracic Surgery, Policlinico Umberto I, Sapienza University of Rome, 00165 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rita","family":"Vaz Sousa","sequence":"additional","affiliation":[{"name":"Division of Thoracic Surgery, Policlinico Umberto I, Sapienza University of Rome, 00165 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valerio","family":"Sebastianelli","sequence":"additional","affiliation":[{"name":"Division of Thoracic Surgery, Policlinico Umberto I, Sapienza University of Rome, 00165 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio Pio","family":"Evangelista","sequence":"additional","affiliation":[{"name":"Division of Thoracic Surgery, Policlinico Umberto I, Sapienza University of Rome, 00165 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"Mattoccia","sequence":"additional","affiliation":[{"name":"Division of Thoracic Surgery, Policlinico Umberto I, Sapienza University of Rome, 00165 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beatrice","family":"Zacchini","sequence":"additional","affiliation":[{"name":"Division of Thoracic Surgery, Policlinico Umberto I, Sapienza University of Rome, 00165 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1061-5773","authenticated-orcid":false,"given":"Tiziano","family":"De Giacomo","sequence":"additional","affiliation":[{"name":"Division of Thoracic Surgery, Policlinico Umberto I, Sapienza University of Rome, 00165 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco","family":"Anile","sequence":"additional","affiliation":[{"name":"Division of Thoracic Surgery, Policlinico Umberto I, Sapienza University of Rome, 00165 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Federico","family":"Venuta","sequence":"additional","affiliation":[{"name":"Division of Thoracic Surgery, Policlinico Umberto I, Sapienza University of Rome, 00165 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2722-4974","authenticated-orcid":false,"given":"Massimiliano","family":"Bassi","sequence":"additional","affiliation":[{"name":"Division of Thoracic Surgery, Policlinico Umberto I, Sapienza University of Rome, 00165 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"48","DOI":"10.1016\/j.jbspin.2012.01.016","article-title":"Incomplete thymic involution in systemic sclerosis and rheumatoid arthritis","volume":"80","author":"Meunier","year":"2013","journal-title":"Joint Bone Spine"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"841","DOI":"10.1016\/j.humpath.2005.05.004","article-title":"Multilocular thymic cyst associated with follicular hyperplasia: Clinicopathologic study of 4 resected cases","volume":"36","author":"Izumi","year":"2005","journal-title":"Hum.
