Her clinical symptoms rapidly resolved. Echocardiography revealed reversible left ventricular dysfunction with apical ballooning and coronary angiography was normal. Based on these findings, we diagnosed takotsubo syndrome. Over the next two months, the patient experienced repeated bouts of elevated sympathetic activity. On workup, we found an adrenal mass and elevated urine metanephrines. After adrenalectomy, histology confirmed pheochromocytoma. Our patient had the rare diagnosis of postpartum pheochromocytoma-induced takotsubo syndrome.<\/jats:p>","DOI":"10.1136\/bcr-2020-240098","type":"journal-article","created":{"date-parts":[[2021,3,19]],"date-time":"2021-03-19T12:20:53Z","timestamp":1616156453000},"page":"e240098","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Postpartum pheochromocytoma-induced takotsubo syndrome"],"prefix":"10.1136","volume":"14","author":[{"given":"Masaki","family":"Itagane","sequence":"first","affiliation":[{"name":"Medicine, Okinawa Chubu Hospital, Uruma, Okinawa, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Nakazato","sequence":"additional","affiliation":[{"name":"Cardiology, Okinawa Chubu Hospital, Uruma, Okinawa, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8342-230X","authenticated-orcid":false,"given":"Mitsuyo","family":"Kinjo","sequence":"additional","affiliation":[{"name":"Medicine, Okinawa Chubu Hospital, Uruma, Okinawa, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,3,19]]},"reference":[{"key":"2025082804263119000_14.3.e240098.1","doi-asserted-by":"publisher","DOI":"10.1097\/00006254-199911000-00025"},{"key":"2025082804263119000_14.3.e240098.2","doi-asserted-by":"crossref","first-page":"458","DOI":"10.1055\/a-0669-9556","article-title":"Catecholamine-Induced cardiomyopathy in pheochromocytoma: how to manage a rare complication in a rare disease?","volume":"51","author":"Santos","year":"2019","journal-title":"Horm Metab Res"},{"key":"2025082804263119000_14.3.e240098.3","doi-asserted-by":"crossref","first-page":"233","DOI":"10.4158\/EP13498.CR","article-title":"Pheochromocytoma presenting as takotsubo-like cardiomyopathy following delivery","volume":"20","author":"J\u00f3\u017awik-Plebanek","year":"2014","journal-title":"Endocr Pract"},{"key":"2025082804263119000_14.3.e240098.4","doi-asserted-by":"crossref","first-page":"2032","DOI":"10.1093\/eurheartj\/ehy076","article-title":"International expert consensus document on takotsubo syndrome (Part I): clinical characteristics, diagnostic criteria, and pathophysiology","volume":"39","author":"Ghadri","year":"2018","journal-title":"Eur Heart J"},{"key":"2025082804263119000_14.3.e240098.5","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2002-021251"},{"key":"2025082804263119000_14.3.e240098.6","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(01)01316-X"},{"key":"2025082804263119000_14.3.e240098.7","doi-asserted-by":"crossref","DOI":"10.1186\/s12884-019-2233-7","article-title":"Takotsubo cardiomyopathy in pregnancy: a case report and literature review","volume":"19","author":"Oindi","year":"2019","journal-title":"BMC Pregnancy Childbirth"},{"key":"2025082804263119000_14.3.e240098.8","first-page":"802","article-title":"Occurrence of pheochromocytoma in Rochester, Minnesota, 1950 through 1979","volume":"58","author":"Beard","year":"1983","journal-title":"Mayo Clin Proc"},{"key":"2025082804263119000_14.3.e240098.9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jamcollsurg.2009.09.022"},{"key":"2025082804263119000_14.3.e240098.10","doi-asserted-by":"publisher","DOI":"10.1097\/00005792-199101000-00004"},{"key":"2025082804263119000_14.3.e240098.11","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjhyper.2005.04.021"},{"key":"2025082804263119000_14.3.e240098.12","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.8976"},{"key":"2025082804263119000_14.3.e240098.13","doi-asserted-by":"crossref","first-page":"241","DOI":"10.1016\/j.ijcard.2011.03.027","article-title":"Takotsubo-like cardiomyopathy in pheochromocytoma","volume":"153","author":"Agarwal","year":"2011","journal-title":"Int J Cardiol"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2020-240098","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T11:27:04Z","timestamp":1756380424000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2020-240098"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,3]]},"references-count":13,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2021,3,19]]},"published-print":{"date-parts":[[2021,3]]}},"alternative-id":["10.1136\/bcr-2020-240098"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2020-240098","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,3]]}}}
