What does a limpoma on adrenal gland mean?

May be: It is probably not causing any problems. This is a fat tumor. Talk to your doctor about this also.

Adrenal mass: A lipoma or other small mass is relatively common but if you have high blood pressure your doctor should check some bloodwork to see if the adrenal is functioning correctly or if the mass is secreting BP raising chemicals. Generally most adrenal masses greater than 5 cm or functioning masses should be removed. An MRI may be able to tell if the smaller masses are serious.
