Adrenal Myelolipoma: A Series of Three Cases

Abstract

Adrenal myelolipomas are rare benign adrenal tumour composed of mature adipocytes intermixed with myeloid tissue. They are second most common cause after adrenal adenomas and comprise 6-16% of all the adrenal incidentalomas. They are often asymptomatic and therefore rarely detected but in recent times due to radiological advancements, these cases are increasingly being detected and therefore treated. Extra-adrenal myelolipoma are the myelolipomas, detected outside the adrenal gland but occurs rarely. Three cases (53 years old male patient, 60 years old male patient and 46 years old female patient) of clinically and radiologically suspected cases of symptomatic adrenal myelolipoma are discussed here. The first case described, presented with right flank pain radiating to back which was suspected as adrenal mass by Computed Tomography (CT) evaluation. The second case presented with right flank pain, haematuria and weight loss which was suspected on Ultrasonography (USG) and Contrast Enhanced Computed Tomography (CECT) as an adrenal mass. The third patient presented with bilateral pedal oedema and suspected adrenal mass was found on USG. All three cases were histopathologically confirmed as adrenal myelolipoma and managed by surgical excision. The uniqueness of the case lies in its early detection due to technological advancements and hence proper management of the patients.
