Adrenal Myelolipoma: Report of Diagnosis by Fine Needle Aspiration

Abstract

We report 2 cases of adrenal myelolipoma. The diagnosis was suspected preoperatively in the first case on the basis of radiographic findings, ultrasonography and computerized tomography, and was confirmed by an operation. In the second case the diagnosis was established by fine needle biopsy. Computerized tomography and ultrasonography help in the preoperative diagnosis of myelolipoma but only fine needle biopsy can differentiate this lesion from a malignant neoplasm and avoid an operation.

Adrenal Myelolipoma Simulating Virilizing Adrenal Tumor

“…All the reported findings are compatible with but not pathognomonic for the diagnosis of adrenal myelolipo ma, therefore, in unclear cases, CT-guided neddle biopsy of the mass may be useful to establish the correct diag nosis [3,13] and thus avoid radical surgery of a benign disease.…”

Ultrasonography and Computed Tomography in Adrenal Myelolipoma

“…Retroperitoneal lipoma is a rare, benign and homogeneous mass without solid components [10], Ret roperitoneal liposarcoma arising in the perinephric space can be distinguished if CT displays irregular margination or local extension [3,6,10,12], CT-guided fine needle aspiration biopsy can be obtained to make a spe cific histologic diagnosis [1,[13][14][15].…”

Myelolipoma of the Adrenal Gland

“…liposarcoma and adrenal tu mors. Ultrasound has the advantage of fine needle aspira tion diagnosis, and if the tumor has no endocrine activity, it may reflect on the decision of conservative manage ment of this benign condition [5], Myelolipomas are usually found in obese and hyper tensive persons, like our cases, and may be associated with endocrine disorders such as hermaphrodism, Cush ing's and Addison's diseases or congenital deficiency of [7], rupture [8] and necrosis [9], Fur thermore, differential diagnostic problems and larger masses which produce pain or symptoms of vague ab dominal and chest discomfort due to their size, as in our cases, are suggested to be managed surgically.…”
