Case contributed by Dr J. Ray Ballinger

Presentation

Lung mass found on chest x-ray

Patient Data

Age: 62 years
Gender: Male
CT

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.

Case Discussion

Adrenal myelolipomas are relatively rare benign adrenal masses containing fat and hematopoietic elements. Occasionally they occur elsewhere in the retroperitoneum.
Myelolipomas account for about 2.6% of primary adrenal masses and have a prevalence of at autopsy of 0.06%. In contrast, lipomas account for only 0.7% of primary adrenal masses.
