Abstract
Adrenocorticotropic hormone production by pancreatic neuroendocrine tumor (PNET) is rare and results in hyperstimulation of the adrenal gland to produce ectopic Cushing syndrome. Our case showcases the safety and effectiveness of percutaneous CT-guided microwave ablation of the adrenal gland in a 49-year-old female with PNET and hepatic metastases who presented with ectopic Cushing syndrome despite surgical resection of the primary pancreatic tumor and left adrenal gland. Prior to ablation, the right adrenal gland measured 4.3×1.6×2.0cm and the patient had malignant hypertension with elevated morning serum cortisol level (1976nmol/L). After microwave ablation of the right adrenal gland, the hypertension resolved and the cortisol level decreased dramatically (74nmol/L). As expected after successful treatment, the patient developed adrenal insufficiency and was placed on glucocorticoid and mineralocorticoid supplementation.
