Its diagnosis is often challenging because of the tumour\u2019s rarity and the non-specific, often paroxysmal nature of symptoms. We present the case of a previously healthy woman in her 30s who developed non-specific symptoms, including nausea, vomiting and palpitations, progressing to cardiogenic shock with severely impaired biventricular function requiring mechanical circulatory support. Further investigations revealed a pheochromocytoma-induced Takotsubo syndrome, which was successfully treated with adrenalectomy. This case report supports current evidence that early recognition and aggressive supportive care, including mechanical circulatory support as a bridge to surgery, can lead to full recovery from severe catecholamine-induced cardiac dysfunction.<\/jats:p>","DOI":"10.1136\/bcr-2025-269482","type":"journal-article","created":{"date-parts":[[2026,1,30]],"date-time":"2026-01-30T11:25:14Z","timestamp":1769772314000},"page":"e269482","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["A rare clinical presentation of pheochromocytoma: a young patient in severe cardiogenic shock with secondary Takotsubo syndrome"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-8426-5282","authenticated-orcid":false,"given":"Andreas","family":"Corraro","sequence":"first","affiliation":[{"name":"Department of Emergency Medicine, Baden Cantonal Hospital, Baden, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Max","family":"Fleck","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Baden Cantonal Hospital, Baden, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philipp","family":"Theil","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Universit\u00e4tsSpital Z\u00fcrich, Z\u00fcrich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Markus","family":"Schwendinger","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Baden Cantonal Hospital, Baden, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2026,1,30]]},"reference":[{"key":"2026013003250774000_19.1.e269482.1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(05)67139-5"},{"key":"2026013003250774000_19.1.e269482.2","doi-asserted-by":"publisher","DOI":"10.1097\/HJH.0b013e32834a4ce9"},{"key":"2026013003250774000_19.1.e269482.3","first-page":"215","article-title":"Cardiovascular Manifestations of Pheochromocytoma","volume":"25","author":"Gu","year":"2017","journal-title":"J Cardiovasc Transl Res"},{"key":"2026013003250774000_19.1.e269482.4","first-page":"276","article-title":"Adrenal incidentaloma: an important component of the clinical presentation spectrum of benign sporadic adrenal pheochromocytoma","volume":"134","author":"Kudva","year":"1999","journal-title":"Arch Surg"},{"key":"2026013003250774000_19.1.e269482.5","doi-asserted-by":"crossref","first-page":"319","DOI":"10.1016\/j.ijcard.2017.07.014","article-title":"Pheochromocytoma as a reversible cause of cardiomyopathy: Analysis and review of the literature","volume":"249","author":"Zhang","year":"2017","journal-title":"Int J Cardiol"},{"key":"2026013003250774000_19.1.e269482.6","doi-asserted-by":"crossref","first-page":"1036","DOI":"10.1002\/ejhf.683","article-title":"A Novel Clinical Score (InterTAK Diagnostic Score) to Differentiate Takotsubo Syndrome from Acute Coronary Syndrome: Results from the International Takotsubo Registry","volume":"19","author":"Ghadri","year":"2017","journal-title":"Eur J Heart Fail"},{"key":"2026013003250774000_19.1.e269482.7","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.121.055854"},{"key":"2026013003250774000_19.1.e269482.8","unstructured":"Sato H , Tateishi H , Uchida T , et al .
