Concurrent pericardial and myocardial infiltration can mimic acute myocardial infarction on electrocardiography, posing diagnostic challenges. Case Presentation: We present a 64-year-old female with biopsy-confirmed DLBCL who developed acute respiratory symptoms and electrocardiographic changes mimicking ST-elevation myocardial infarction (STEMI). Multimodal imaging revealed a large pericardial effusion, myocardial infiltration, and no obstructive coronary disease. Despite chemotherapy and supportive care, the patient succumbed to cardiopulmonary failure. Conclusion: This case highlights a rare manifestation of lymphoma-associated cardio-infiltration presenting as STEMI mimic. Early multidisciplinary evaluation is essential to differentiate pseudo-infarction syndromes and prevent unnecessary invasive interventions.<\/jats:p>","DOI":"10.1159\/000550935","type":"journal-article","created":{"date-parts":[[2026,6,1]],"date-time":"2026-06-01T16:03:55Z","timestamp":1780329835000},"page":"758-766","source":"Crossref","is-referenced-by-count":0,"title":["Tumor-Related Pericardial and Myocardial Infiltration in Diffuse Large B-Cell Lymphoma Presenting as an ST-Elevation Myocardial Infarction Mimic: A Case Report"],"prefix":"10.1159","volume":"19","author":[{"given":"Zhandos","family":"Burkitbayev","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8336-391X","authenticated-orcid":false,"given":"Ainur","family":"Bilmakhanbetova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aliya","family":"Omarbek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kulshat","family":"Aidarbekova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Assel","family":"Zhumabekova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aigerim","family":"Tanyrbergenova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-8934-8327","authenticated-orcid":false,"given":"Bairam","family":"Kochiev","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandr","family":"Kolesnev","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2026,6,1]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1253\/jcj.60.389"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1093\/ehjcr\/ytab192"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2015-210821"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaccas.2020.02.004"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.3390\/cancers16122150"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1186\/s40959-024-00244-2"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.3389\/fcvm.2024.01342"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1253\/circj.CJ-23-0521"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1097\/CRD.0000000000000505"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2011.38.4798"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/S1010-7940(01)00848-0"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1186\/s12245-021-00352-x"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000022992"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.cjca.2025.01.002"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1097\/CRD.0000000000000469"}],"container-title":["Case Reports in Oncology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000550935","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,19]],"date-time":"2026-06-19T16:00:57Z","timestamp":1781884857000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000550935"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6,1]]},"references-count":15,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026,1,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000550935","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.32530158","asserted-by":"subject"}]},"ISSN":["1662-6575"],"issn-type":[{"value":"1662-6575","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,6,1]]}}}
