LBODP014 Hyperaldosteronism Caused By Adrenal Cyst

Cyst adrenal lesions are uncommon with a reported incidence in autopsies of 0. 064% to 0.18%. Functional adrenal cysts are rarer, to our knowledge with 3 cases reported in the literature, 2 producing catecholamines and 1 producing aldosterone. Clinical case: A 39-year-old male patient with arterial hypertension since the age of 38 without target organ involvement or hydroelectrolytic alterations was taken to studies of secondary hypertension, as a positive finding we found aldosterone in 10.5 ng/dl (n <10 ng/dl) and direct renin 0. 0296 mU/L (n >1 mU/L) for an aldosterone-renin ratio of 354 (n <3.7); Confirmation of hyperaldosteronism was performed with a saline solution suppression test, with basal aldosterone of 14.4 ng/dl and post saline of 9.53 ng/dl. (n <5ng/dl). He was taken to localization studies with contrast-enhanced CT scan of the abdomen, finding a low-density left adrenal adenoma. A laparoscopic adrenalectomy was performed, on pathology an adrenal cyst was report without nodular lesions. 4 months later clinical and biochemical resolution was confirmed.

This patient is the 4th case published in the literature of a biochemically confirmed functional adrenal cyst, which is important in order not to rule out the presence of adrenal cysts as a possible etiology of hormone overproduction.
