In brief: Different tumor type

An adrenal adenoma is just made up of adrenal cortical cells (the normal cells of the gland).
A myelolipoma is composed of mature fat and bone marrow elements (also normal). This tumor has a very specific appearance by imaging -- and is usually not a functional tumor. It does not have to be removed, unless there are symptoms.

In brief: Myelolipoma = fat

Myelolipomas have predominately fat density on ct scan and are almost always benign and do not produce hormones.
Adrenal adenomas resemble normal adrenal tissue and may produce hormones.
