Non-Hodgkin lymphoma under work-up.

Patient Data

Age: 50 years
Gender: Male

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).
