Single-Port Robotic Left Retroperitoneal Mass Excision of Paraganglioma

Introduction: A 44-year-old woman with a BMI of 49 presented to our clinic with a 2.6 cm left retroperitoneal mass. She had a 3-year history of headaches, flushing, anxiety, and uncontrolled blood pressure despite several antihypertensive medications. She underwent a metabolic work-up with a negative dexamethasone suppression test and elevated plasma metanephrine level (normetanephrine 2.83 nmol/L, which is more than twice the upper limit of normal). A Dotatate PET scan confirmed paraganglioma or pheochromocytoma in the left retroperitoneum. Upon referral to endocrinology, she was started on 2 mg of doxazosin daily, and 4 days later, was also given 25 mg of atenolol daily.
