Adrenal CT scan of woman with poorly controlled hypertension
Adrenal CT scan of a 37-year-old woman with poorly controlled hypertension despite taking 3 antihypertensive drugs. The scan shows an 18-mm right adrenal nodule (arrow, left panel) and 2 left adrenal nodules of 7 mm and 4 mm (arrows, right panel). Adrenal venous sampling lateralized the aldosterone secretion to the right adrenal gland. A cortical adenoma (20×17×12 mm) was found at laparoscopic right adrenalectomy. At 18 months after surgery, the patient's postoperative plasma aldosterone concentration was low, and her blood pressure was normal without the aid of antihypertensive medications.
