A 51-year-old woman is evaluated following an emergency department visit for abdominal pain. The pain spontaneously resolved. A CT scan in the emergency department revealed an incidentally discovered 1.4-cm left adrenal nodule with smooth borders and low attenuation and vascularity. She is otherwise healthy and takes no medications, On physical examination, blood pressure is 120/80 mm Hg, pulse rate is 60/min, and respiration rate is 14/min. The remainder of the physical examination is normal. A comprehensive metabolic profile, including electrolytes, is normal. Which of the following diagnostic tests should be done next?

الإجابة: C. Plasma metanephrine levels and overnight dexamethasone suppression test
Even a small, benign-looking incidentaloma needs a functional work-up: plasma metanephrines (pheochromocytoma) and an overnight 1 mg dexamethasone suppression test (subclinical Cushing).
- She is normotensive with normal electrolytes, so an aldosterone/renin ratio is not required; DHEA-S/testosterone are not part of routine screening.
ليش كل خيار صح أو غلط

A
ليش غلط
The aldosterone/renin ratio is for patients with hypertension; she is 120/80 with normal electrolytes, and this choice omits the plasma metanephrines.

B
ليش غلط
Aldosterone/renin is for hypertensive patients, and DHEA-S/testosterone address androgen-secreting tumours (virilization in women); this choice also omits metanephrines and the dexamethasone test.

C
ليش صح
Every incidentaloma is screened for pheochromocytoma (plasma metanephrines) and Cushing syndrome (overnight 1 mg dexamethasone suppression test).

D
ليش غلط
Metanephrines are right, but DHEA-S/testosterone are for androgen-secreting tumours (virilization in women) and this choice omits the overnight dexamethasone suppression test for Cushing.
