Detection of severe hypertension in a patient with neurofibromatosis type 1 during anesthesia induction: a case report

Abstract

Abstract Background Neurofibromatosis type 1 has a higher prevalence of pheochromocytoma and paraganglioma than the general population: 1.0–5.7% versus 0.2–0.6%. Currently, there are no generally accepted guidelines for screening for pheochromocytoma and paragangliomas in asymptomatic patients with neurofibromatosis type 1. Case presentation Severe hypertension developed during anesthesia induction in our patient, a 44-year-old Chinese man with neurofibromatosis type 1. We screened for catecholamine level after glioma resection, and the patient was diagnosed with combined pheochromocytoma and paraganglioma. Conclusions A delay in diagnosis or lack of a diagnosis in pheochromocytoma and paraganglioma may increase the perioperative morbidity and mortality risk due to excess catecholamine secretion. Therefore, routine pheochromocytoma and paraganglioma screening preoperatively in patients with neurofibromatosis type 1 is very important.
