BackgroundPatients with pheochromocytomas are often diagnosed with acute myocardial infarction (AMI) due to initial symptoms of palpitations and chest tightness. We describe a case of AMI syndrome where a giant paraganglioma was unexpectedly identified. The anesthetic management of the paraganglioma resection was challenging and complex.Case PresentationA 66-year-old woman was admitted to the emergency department for complaints of palpitations, chest tightness and vomiting. A laboratory test revealed that troponin I and N-terminal pro-brain natriuretic peptide levels were dramatically increased. Emergency percutaneous coronary angiography (CAG) showed normal coronary arteries. In addition, the serum levels of free catecholamines were increased, and computed tomography and magnetic resonance imaging revealed a heterogenous mass lesion in the right retroperitoneal. All of this ultimately confirmed the diagnosis of pheochromocytoma. After three weeks of careful preoperative preparation by a multidisciplinary team, and an anesthesiologist team develops detailed perianesthesia management strategies to maintain hemodynamics and blood glucose stability and regulate acid-base balance, pheochromocytoma resection was performed successfully. About 2 weeks later, the patient was discharged healthy. A postoperative pathology test confirmed paraganglioma.ConclusionsTo our knowledge, giant pheochromocytoma resection is a complex challenge for the anesthesiologists, this clinical case may supply a thoughtful experience for anesthetic management in the resection of giant pheochromocytomas. Adequate preoperative evaluation and prudent perianesthesia management by anesthesiologists are important guarantees for patients to obtain a good prognosis and discharge healthily.© 2022.
