BACKGROUND Pheochromocytoma is a rare catecholamine-secreting tumor of neuroendocrine origin. It has a prevalence of <1% in adults with hypertension. In some cases, hypertension is associated with the classical triad of headache, sweating, and tachycardia. Cardiogenic shock due to stress-induced cardiomyopathy caused by catecholamine excess may rarely be the initial symptom of pheochromocytoma, mimicking Takotsubo Syndrome. METHODS We report the case of a 58-year-old female patient with pheochromocytoma-induced cardiogenic shock (PICS) in the early postoperative period after thyroidectomy. RESULTS PICS is caused by a catecholamine storm, which induces myocardial stress and cardiac dysfunction. In such cases, early management with mechanical circulatory assistance may be promptly considered, given the increased risk of mortality. CONCLUSION PICS is a rare and serious condition. Prompt diagnosis and adequate resuscitation measures are necessary to avoid high mortality.
