Axial C+ portal venous phase
An incidentally discovered well-circumscribed mass in the left adrenal gland, with fat-containing components.
Case Discussion
The proportion of fatty tissue in a myelolipoma is variable, ranging from only a few small regions in an otherwise mostly soft tissue density mass (10%) to masses made up of roughly equal components of fat and soft tissue (50%) or almost completely composed of fatty tissue (40%).
Small punctate calcifications may be seen in 25-30% of cases.
If hemorrhage is present then regions of higher attenuation may be seen. This is more frequently seen in large lesions (>10 cm).
