Intraoperative Hemodynamic Instability and Diagnosis of Pheochromocytoma During Excision of Adrenal Incidentaloma With Incomplete Workup: A Case Report.

Preoperative evaluation of incidentalomas for pheochromocytoma is imperative. This case report describes a scheduled adrenalectomy in an asymptomatic patient with what was eventually determined to be an incomplete biochemical workup. The intraoperative course was complicated by labile and rapid increases in blood pressure and heart rate, suggesting the missed diagnosis of pheochromocytoma. It is important for anesthesiologists to ensure adequate preoperative biochemical workup before excluding the possibility of coexisting pheochromocytoma.
