Symptomatic giant adrenal myelolipoma associated with cholelithiasis: Two case reports

Abstract

In this article, we have discussed about two cases of adrenal myelolipoma and aim to discuss the role of imaging in their diagnosis and their management. Different imaging techniques such as ultrasound, computed tomography and magnetic resonance imaging were used to aid in diagnosis in each of the cases. The findings have been highlighted here. In each of the cases, the diagnosis could be confirmed by imaging, and there was cholelithiasis seen associated with unilateral adrenal myelolipoma. Adrenal myelolipomas are rare, benign, non-functional tumors of adrenal gland. Most tumors are unilateral and small; bilateral, giant myelolipomas are extremely rare. The association of adrenal myelolipoma with gallstones is uncommon. To our knowledge only two cases of such an association have been reported in the literature. However, the possibility does exist and steps should be taken to ensure a complete diagnosis. Also, it is important to understand the key points which help us in diagnosing adrenal myelolipomas by imaging.
