Undiagnosed pheochromocytoma poses significant intraoperative challenges to the anesthesiologist. These tumors generally cause profound hypotension after spinal anesthesia. We present an unusual case of a hypertensive crisis occurring in a patient under spinal anesthesia. Due to intraoperative hemodynamic instability, the case was converted to general anesthesia with a volatile anesthetic. Postoperative workup was consistent with a pheochromocytoma. Pheochromocytomas are rare, but given their significant intraoperative morbidity and mortality, they should be considered in the differential diagnosis of unexpected intraoperative hemodynamic changes.
