Preoperative 18F‐FDG Uptake is Strongly Correlated with Malignancy, Weiss Score, and Molecular Markers of Aggressiveness in Adrenal Cortical Tumors

Abstract

The nature of atypical adrenal masses can be difficult to define during preoperative investigations. For undetermined tumours smaller than 6 cm, characterization with PET-FDG can be one more diagnostic argument pointing to malignancy. It could potentially change the therapeutic strategy and surgical management. In our experience, molecular analyses are available after surgery and have less impact on the therapeutic strategy than PET-FDG. Preoperative PET-FDG can be an asset in the management of adrenal incidentaloma and adrenocortical carcinoma.
