In 2016, the European Society of Endocrinology (ESE), in collaboration with the European Network for the Study of Adrenal Tumors, asserted that adrenal incidentalomas <4 cm and ≤10 Hounsfield units do not require follow-up imaging.
A paper recently published in the European Journal of Endocrinology reports results of a study designed specifically to assess the application of the recommended follow up strategies.
The retrospective cohort study looked at clinical characteristics and natural course of incidental adrenal masses in a single center over 13 years in more than 1000 patients.
The authors conclusions helped validate recommendations from the ESE that no follow up imaging is needed for adrenal masses less than 4 cm that have clearly benign features.
