ABSTRACT

Adrenal incidentalomas (AI) are increasingly common due to modern use of several imaging modalities. Adrenal adenomas comprise 75% of all adrenal incidentalomas while adrenal myelolipomas (AML) are the second most common. Several studies report different incidence rates for AML ranging from 2.6% to 6%. Other differentials for adrenal tumors include: pheochromocytoma, adrenocortical carcinoma, metastatic cancer, hematomas, hormone-producing tumors and adrenal hyperplasia. On this case report, we discuss a patient with bilateral adrenal tumors - a right adrenal adenoma and a left myelolipoma.We discuss the embryology, pathophysiology, histology, and clinical importance of myelolipoma to create awareness in the medical community. The clinical awareness of myelolipoma may help to decrease cost of care by decreasing the need for unnecessary medical procedures and repeat imaging.
