Findings and Diagnosis
A well-circumscribed fatty mass is seen in the right adrenal gland on these contrast enhanced images. This is most consistent with a benign myelolipoma. The differential diagnosis would include a benign lipoma which is less commonly seen.
The image below was obtained 3 months later showing a stable appearance to the mass.
Myelolipomas are relatively rare benign adrenal masses containing fat and hematopoetic elements. Occasionally they occur elsewhere in the retroperitoneum.
