Adrenal myelolipoma is a rare benign tumor composed of mature lipomatous and hemopoietic tissue. Although it is often discovered as an incidental finding on imaging of the abdomen for some other reason or at autopsy, adrenal myelolipoma has been reported to present with symptoms such as flank pain resulting from tumor bulk, necrosis, or spontaneous retroperitoneal hemorrhage. Myelolipomas are hormonally inactive but have also been reported to coexist with other hormonally active tumors of the adrenal gland. They are usually unilateral but may be bilateral and may also develop in extraadrenal sites like the retroperitoneum, thorax, and pelvis. We report a patient with symptomatic adrenal myelolipoma diagnosed on computed tomography scan and confirmed on computed tomography-guided biopsy. The patient underwent surgical resection for symptomatic relief. We also review the literature to evaluate the presentation and optimal management of this rare adrenal tumor that is not encountered by most general surgeons and therefore not well known to most surgeons.

Insulinoma-associated protein 1 (INSM1) is a relatively new immunostain used in the diagnostic assessment of tumors with neuroendocrine differentiation. While INSM1 positivity has been described in some non-neuroendocrine neoplasms, reactivity in red blood cells (RBCs) has only been anecdotally noted in one prior study without description of the degree/extent of staining. INSM1 staining in nucleated erythroid precursors has not been previously reported.

Myelolipoma of the adrenal gland is a rare, benign, non-functioning tumor characterized by the presence of adipose tissue and bone marrow elements. We present the case of a 48-year-old woman with intermittent left flank pain and an incidental finding of an adrenal tumor on computed tomography. The patient underwent laparoscopic tumor resection due to the large size of the tumor.

Adrenal incidentalomas are increasingly identified through advanced imaging, posing diagnostic challenges due to their varied benign and malignant nature. We present the case of a 29-year-old male who, during evaluation for left renal colic, was found to have a 5.5 cm heterogeneous right adrenal mass on non-contrast CT, initially suggestive of a myelolipoma.

Adrenal diseases pose significant diagnostic challenges due to the wide range of neoplastic and non-neoplastic pathologies. Radiologists have a crucial role in diagnosing and managing these conditions by, leveraging advanced imaging techniques. This review discusses the vital role of computed tomography (CT), magnetic resonance imaging (MRI), and nuclear medicine in adrenal imaging, and focuses on morphological and functional evaluations.
