ABSTRACT:
Primary hyperaldosteronism is not as uncommon as we thought, and by recent estimates the prevalance may be as high as 11% among hypertensives. We present a case of a 33 years old male patient came with a complaint of headache in occipital area & weakness in both lower limb since 4 weeks. The patient was a diagnosed case of hypertension and was already on tablet Atenolol (25 mg) once a day. At the time of admission, the patient was found to have a pulse of 96/min and blood pressure of 170/100 mm of Hg. Power was 3/5 for both right and left lower limbs. At the time of admission, serum potassium was 2.8. As a result, the patient was shifted to tablet Metroprolol and Amlodipine (50 + 5 mg) once a day. We also added tablet Cilnidipine (10 mg) and Telmisartan (80 mg) once a day and syrup Potklor thrice a day with water. The patient was sent for renal artery doppler, urine for metanephrines and vanillylmandelic acid, serum aldosterone, plasma aldosterone/plasma renin activity ratio (PAC/PRA ratio), urinary aldosterone, urinary cortisol and adrenocorticotrophic hormone level and computed tomography (CT) abdomen to rule out hyperaldostronism. Plasma aldosterone/plasma renin activity ratio, urinary aldosterone was high and CT abdomen revealed a solitary nodule in the left adrenal gland measuring 1.2 × 1.0 cm in maximum transverse diameter, which was suggestive of adrenal adenoma. Diagnosis of Conn’s syndrome secondary to adrenal adenoma was made. The patient was advised tablet Aldactone (25 mg) once a day and serum electrolytes were repeated which showed normalization with normal blood pressure.
