A Case of Adrenocortical Adenoma Causing Cushing's Syndrome with Contralateral Nonfunctioning Adenoma / 대한내분비학회지

ABSTRACT

We report the case of a 43-year-old woman with Cushing's syndrome showing bilateral adrenococortical adenomas. We performed bilateral selective adrenal vein samplings. Hypersecretion of cortisol on the left sided adrenal tumor was observed, but no evidence of cortisol hypersecretion from the adrenal tumor on the right side was observed. The left adrenal tumor was resected selectively, but the right adrenal gland was reserved. The left adrenal tumor was histologically diagnosed as a adrenal adenoma without any evidence of nodular hyperplasia. Following the resection of the left adrenal gland, no cortisol hypersecretion from the remaining adrenal tumor on the right side was observed until now, suggesting that a selective adrenalectomy of functioning adenoma may be an acceptable treatment modality.
