It usually presents with nodal involvement (cervical, mediastinal, or abdominal), but approximately 30% of patients will exhibit extranodal involvement, with 2-4% presenting as a primary cardiac mass. Multimodal imaging is essential to distinguish these masses from other common benign lesions and to assist in surgical planning. Here, we report a case of DLBCL manifested as a right atrial mass, pericardial e\ufb00usion, and cardiac tamponade. Transesophageal echocardiogram (TEE) and cardiac magnetic resonance imaging (CMR) were complementary to transthoracic echocardiogram in diagnosing the cardiac neoplasm, with positron emission tomography (PET-CT) aiding in staging and localizing the primary tumor. Biopsy of the cardiac mass or extracardiac involvement confirms the histopathological subtype and guides the treatment. Although primary and secondary cardiac tumors have poor outcomes, early diagnosis and aggressive treatment can influence prognosis.<\/jats:p>","DOI":"10.56305\/001c.144088","type":"journal-article","created":{"date-parts":[[2025,10,1]],"date-time":"2025-10-01T14:41:25Z","timestamp":1759329685000},"source":"Crossref","is-referenced-by-count":0,"title":["Di\ufb00use Large B Cell Lymphoma presenting as Right Atrial Mass and Cardiac Tamponade"],"prefix":"10.56305","volume":"4","author":[{"given":"Chinmayi","family":"Kothari","sequence":"first","affiliation":[{"name":"All India Institute of Medical Sciences, New Delhi","department":["Department of Internal Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lakshmi","family":"Kattamuri","sequence":"additional","affiliation":[{"name":"Texas Tech University Health Sciences Center, El Paso","department":["Department of Internal Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prasana","family":"Ramesh","sequence":"additional","affiliation":[{"name":"University of Massachusetts-Baystate Health","department":["Department of Internal Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziad","family":"Zalaquett","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03xjacd83","id-type":"ROR","asserted-by":"publisher"}],"name":"Cleveland Clinic","department":["Division of Cardiology, Department of Internal Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"Collier","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03xjacd83","id-type":"ROR","asserted-by":"publisher"}],"name":"Cleveland Clinic","department":["Division of Cardiology, Department of Internal Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ben","family":"Alencherry","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03xjacd83","id-type":"ROR","asserted-by":"publisher"}],"name":"Cleveland Clinic","department":["Division of Cardiology, Department of Internal Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aravinda","family":"Nanjundappa","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03xjacd83","id-type":"ROR","asserted-by":"publisher"}],"name":"Cleveland Clinic","department":["Division of Cardiology, Department of Internal Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"35509","published-online":{"date-parts":[[2025,10,1]]},"reference":[{"issue":"5","key":"ref1","doi-asserted-by":"publisher","first-page":"1369","DOI":"10.1148\/rg.325115126","article-title":"From the radiologic pathology archives: cardiac lymphoma: radiologic-pathologic correlation","volume":"32","author":"J.
