Examination revealed pallor and decreased breath sounds on the right side of the chest. On transthoracic echocardiography, there was moderate pericardial effusion with features of constrictive pericarditis. Cardiac magnetic resonance imaging confirmed thickened pericardium with septations and multiple pockets in the pericardial cavity filled with pericardial effusion along with late gadolinium enhancement. Despite all the supportive treatment, the patient\u2019s condition worsened and pericardiectomy was planned. During surgery, the pericardium was found to be densely adherent to the myocardium and highly vascular; therefore, the procedure was abandoned. However, multiple pericardial biopsies were taken, which later revealed high-grade B-cell lymphoma. Postoperatively, the patient developed worsening shock. Despite aggressive resuscitation, her condition continued to decline, and her family chose no further escalation of care. The patient eventually passed away.<\/jats:p>","DOI":"10.1136\/bcr-2025-268261","type":"journal-article","created":{"date-parts":[[2025,11,24]],"date-time":"2025-11-24T02:05:15Z","timestamp":1763949915000},"page":"e268261","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Constrictive pericarditis secondary to underlying pericardial lymphoma"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-3382-9279","authenticated-orcid":false,"given":"Ateeb Mahmood","family":"Khan","sequence":"first","affiliation":[{"name":"Section of Cardiology, Department of Medicine, The Aga Khan University Hospital, Karachi, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3391-1973","authenticated-orcid":false,"given":"Umair","family":"Javed","sequence":"additional","affiliation":[{"name":"Section of Cardiology, Department of Medicine, The Aga Khan University Hospital, Karachi, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8148-0194","authenticated-orcid":false,"given":"Fateh Ali Tipoo","family":"Sultan","sequence":"additional","affiliation":[{"name":"Section of Cardiology, Department of Medicine, The Aga Khan University Hospital, Karachi, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,11,23]]},"reference":[{"key":"2025112318050673000_18.11.e268261.1","first-page":"87","article-title":"Effusive-Constrictive Pericarditis Secondary to Primary Pericardial Lymphoma: A Case Report","volume":"3","author":"Anaya-Cisneros","year":"2012","journal-title":"World J Oncol"},{"key":"2025112318050673000_18.11.e268261.2","first-page":"1745","article-title":"Primary cardiac lymphoma: a case report and review of literature","volume":"13","author":"Chen","year":"2020","journal-title":"Int J Clin Exp Pathol"},{"key":"2025112318050673000_18.11.e268261.3","doi-asserted-by":"crossref","first-page":"S253","DOI":"10.1016\/j.ihj.2016.01.006","article-title":"CD20 negative B-cell lymphoma presenting as constrictive pericarditis: Rare etiology of acute heart failure","volume":"68","author":"Jariwala","year":"2016","journal-title":"Indian Heart J Teach Ser"},{"key":"2025112318050673000_18.11.e268261.4","doi-asserted-by":"crossref","DOI":"10.1093\/ehjcr\/ytad463","article-title":"Brugada phenocopy with altered ST-segment elevation in pericardial diffuse large B-cell lymphoma and effusive-constrictive pericarditis: a case report","volume":"7","author":"Ishibashi","year":"2023","journal-title":"Eur Heart J Case Rep"},{"key":"2025112318050673000_18.11.e268261.5","doi-asserted-by":"crossref","first-page":"689","DOI":"10.1016\/j.rcl.2016.03.006","article-title":"Cardiac Lymphoma","volume":"54","author":"Jeudy","year":"2016","journal-title":"Radiol Clin North Am"},{"key":"2025112318050673000_18.11.e268261.6","doi-asserted-by":"crossref","first-page":"208","DOI":"10.1016\/j.ijcard.2006.11.159","article-title":"A rare cause of constrictive pericarditis: primary cardiac lymphoma","volume":"123","author":"Ho","year":"2008","journal-title":"Int J Cardiol"},{"key":"2025112318050673000_18.11.e268261.7","doi-asserted-by":"crossref","first-page":"510","DOI":"10.1002\/hon.2301","article-title":"Primary cardiac lymphoma: diagnosis, treatment and outcome in a modern series","volume":"35","author":"Carras","year":"2017","journal-title":"Hematol Oncol"},{"key":"2025112318050673000_18.11.e268261.8","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcard.2010.02.016"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2025-268261","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,11,24]],"date-time":"2025-11-24T02:05:16Z","timestamp":1763949916000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2025-268261"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,11]]},"references-count":8,"journal-issue":{"issue":"11","published-online":{"date-parts":[[2025,11,23]]},"published-print":{"date-parts":[[2025,11]]}},"alternative-id":["10.1136\/bcr-2025-268261"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2025-268261","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,11]]}}}
