Lesions arising in the cardiophrenic angle can pose a diagnostic challenge, as they may mimic other mediastinal cystic lesions on imaging. We report the case of a 43-year-old male who was incidentally found to have a well-defined lesion in the right cardiophrenic angle on contrast-enhanced computed tomography. The mass appeared as a heterogeneously enhancing solid\u2013cystic lesion closely abutting the pericardium, raising suspicion for a cystic mediastinal lesion. The patient underwent robotic-assisted thoracoscopic excision of the mass. Intraoperatively, the lesion was well encapsulated and separable from surrounding structures. Complete excision was achieved without the need for pericardial resection. Histopathological examination confirmed the diagnosis of a thymoma. This case highlights the diagnostic challenges associated with unusual mediastinal masses and demonstrates the feasibility and effectiveness of robotic-assisted minimally invasive resection.<\/jats:p>","DOI":"10.4103\/jmas.jmas_36_26","type":"journal-article","created":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T12:00:07Z","timestamp":1786708807000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Robotic excision of an ectopic thymoma in the cardiophrenic angle presenting as a cystic mediastinal mass"],"prefix":"10.4103","author":[{"given":"Abhinav","family":"Deshpande","sequence":"first","affiliation":[{"name":"Department of Surgical Oncology and Robotic Oncosurgery, Max Healthcare, Nagpur, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kawadu Shivdas","family":"Jawade","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology and Robotic Oncosurgery, Max Healthcare, Nagpur, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nitin","family":"Wadaskar","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Max Healthcare, Nagpur, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ketan","family":"Chaturvedi","sequence":"additional","affiliation":[{"name":"Department of Neurology, Max Healthcare, Nagpur, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amol","family":"Dongre","sequence":"additional","affiliation":[{"name":"Department of Medical Oncology, Max Healthcare, Nagpur, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahesh","family":"Deshmukh","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, Max Healthcare, Nagpur, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kapilnath","family":"Muralimanohar","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology and Robotic Oncosurgery, Max Healthcare, Nagpur, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nimish","family":"Ganvir","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology and Robotic Oncosurgery, Max Healthcare, Nagpur, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,8,13]]},"reference":[{"key":"R2-20260814","first-page":"4297","article-title":"Ectopic thymoma: Report of 2 cases and review of the literature","volume":"12","author":"Wu","year":"2019","journal-title":"Int J Clin Exp Pathol"},{"key":"R3-20260814","doi-asserted-by":"crossref","first-page":"245","DOI":"10.1007\/s00428-016-1967-0","article-title":"The spectrum of ectopic thymomas","volume":"469","author":"Weissferdt","year":"2016","journal-title":"Virchows Arch"},{"issue":"(Suppl 3)","key":"R4-20260814","doi-asserted-by":"crossref","first-page":"5884","DOI":"10.1007\/s12070-021-02481-4","article-title":"Ectopic cervical thymoma: An uncommon entity","volume":"74","author":"Kairanna","year":"2022","journal-title":"Indian J Otolaryngol Head Neck Surg"}],"container-title":["Journal of Minimal Access Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/jmas.jmas_36_26","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T12:00:08Z","timestamp":1786708808000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/jmas.jmas_36_26"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,8,13]]},"references-count":3,"URL":"https:\/\/doi.org\/10.4103\/jmas.jmas_36_26","relation":{},"ISSN":["0972-9941","1998-3921"],"issn-type":[{"value":"0972-9941","type":"print"},{"value":"1998-3921","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,8,13]]},"assertion":[{"value":"2026-01-15","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-03-30","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
