Fine‐Needle Aspiration Biopsy of Adrenal Gland Lesions: The Roles of Image Guidance, Rapid On‐Site Evaluation and Additional Tissue Sampling

Our study demonstrates that FNA has great efficacy for evaluation of adrenal lesions, either via EUS or CT guidance. Incorporation of ROSE evaluation into FNA procedure does not directly affect the performance of FNA biopsy but may help direct additional tissue sampling to salvage the cases with a non-diagnostic or indeterminate cytology diagnosis, increasing diagnostic yield.
