A 42-year-old woman presents with progressive muscle weakness, hypokalemia (K+ 2.8 mEq/L), and hypertension over 6 months. Laboratory studies reveal metabolic alkalosis, suppressed plasma renin activity, and elevated aldosterone levels despite sodium repletion. Imaging shows a 1.5 cm left adrenal mass. Which of the following is the most likely diagnosis?

  1. A)Adrenal insufficiency with compensatory hypertension
  2. B)Pheochromocytoma with concurrent hypertension
  3. C)Cushing syndrome with hypertensive manifestations
  4. D)Secondary aldosteronism due to renal artery stenosis
  5. E)Primary aldosteronism due to aldosterone-producing adenomaGABARITO

Explicação

Primary aldosteronism (Conn syndrome) presents with hypertension, hypokalemia, metabolic alkalosis, and suppressed plasma renin activity—the key finding distinguishing it from secondary causes. The elevated aldosterone-to-renin ratio (>30) and adrenal adenoma ... Ver explicação completa e trilha adaptativa →
