Adrenal Myelolipoma Associated with Contralateral Secretory Adenoma: A Case Report

Adrenal myelolipomas are benign lipomatous tumors containing myeloid cell elements, most of which present as adrenal incidentalomas and account for 6% of all adrenal masses. Adrenal myelolipomas are usually unilateral in size, most often discovered in midlife, and affect both sexes almost equally. On imaging, adrenal myelolipomas have pathognomonic imaging features consistent with the presence of gross fat. Large adrenal myelolipomas may cause symptoms of mass effect and may occasionally be complicated by hemorrhage. If there is a concomitant adenoma or adrenal hyperplasia, excess adrenal hormones may be detected in patients with adrenal myelolipoma. We report the case of an adrenal myelolipoma associated with a contralateral secretory adenoma, responsible for Cushing syndrome in the patient.
