Introduction
Lipoma of the adrenal gland is rare with a reported incidence of between 2% to 4%. Improved imaging techniques have helped in the diagnosis of these lesions.
Case presentation
We report an incidentally detected giant adrenal lipoma in a 43-year-old Asian man with a six year history of hypertension. He had a myocardial infarction one year earlier, for which he was taking an antiplatelet agent in addition to antihypertensive medication.
The tumor was detected by computed tomography and magnetic resonance imaging, and was a large, well-defined, altered signal intensity lesion 12 cm in size in the right suprarenal region. The tumor was resected laparoscopically and sent for histopathologic evaluation. It measured 15 cm × 11.5 cm × 6.5 cm on gross examination, weighed 810 g and had a homogenous yellow cut surface. The postoperative course was smooth. Microscopy revealed mature adipose tissue with myxoid degeneration. Over the course of a four month follow-up the patient recovered.
Conclusion
Giant lipoma of the adrenal gland, a benign tumor, is rare compared with myelolipoma. Improved radiologic modalities have led to increased reporting of these benign tumors. Laparoscopic removal of the tumor has helped in early recovery and in reinstating patients to normal lives.
