Catecholamine producing tumor -> not likely since the presentation would be more of an intemittent episode of HTN and other sympathetic symptoms
Decreased distensibility caused by atherosclerosis: could be describing RAS which is discounted by the lack of abdominal bruits
Execess production of ANP -> can be seen in volume overload states and would also result in a reduction of Na+ in the serum due to the actions of ANP- maximal point of impulse not displaced, no edema, low-normal resp.
Juxtaglomeular cell hypertrophy and sclerosis -> this would suggest findings of diabetic nephropathy. Patient doesnt have hx or HTN.
along with patients labs suggesting high aldosterone state - answer is most likely pointing toward autonomous production of aldosterone.
305charlie94if aldosterone is increased, and aldosterone increases NaCl retention, then why is the Cl low here? Wouldn't it have to be increased as well with the sodium? +
