Abstract
SUMMARY: We describe a 56-year-old postmenopausal woman with hypertension, hypokalemia and severe alopecia who was found to have a 4.5-cm lipid-poor left adrenal mass on CT scan performed to evaluate her chronic right-sided abdominal pain. Hormonal studies revealed unequivocal evidence of primary aldosteronism and subclinical hypercortisolemia of adrenal origin. Although a laparoscopic left adrenalectomy rendered her normotensive, normokalemic and adrenal insufficient for 2.5 years, her alopecia did not improve and she later presented with facial hyperpigmentation acne, worsening hirsutism, clitoromegaly, and an estrogen receptor-positive breast cancer. Further testing demonstrated markedly elevated serum androstenedione and total and free testosterone and persistently undetectable DHEAS levels. As biochemical and radiologic studies ruled out primary adrenal malignancy and obvious ovarian neoplasms, a bilateral salpingo-oophorectomy was undertaken, which revealed bilateral ovarian hyperthecosis. This case highlights how the clinical manifestations associated with hyperaldosteronism and hypercortisolemia masqueraded the hyperandrogenic findings. It was only when her severe alopecia failed to improve after the resolution of hypercortisolism, hyperandrogenic manifestations worsened despite adrenal insufficiency and an estrogen receptor-positive breast cancer was found, did it becomes apparent that her symptoms were due to ovarian hyperthecosis. LEARNING POINTS: As cortisol cosecretion appears to be highly prevalent in patients with primary aldosteronism, the term 'Connshing' syndrome has been suggested. The associated subclinical hypercortisolemia could be the driver for the increased metabolic alterations seen in patients with Conn syndrome. The identification of these dual secretors before adrenal venous sampling could alert the clinician about possible equivocal test results. The identification of these dual secretors before unilateral adrenalectomy could avoid unexpected postoperative adrenal crises. Hyperfunctioning adrenal and ovarian lesions can coexist, and the clinical manifestations associated with hypercortisolemia can masquerade the hyperandrogenic findings.
