A significant proportion of adrenal incidentalomas are functioning or malignant, highlighting the need for detailed endocrine and imaging evaluation.
Adrenal incidentalomas may include functioning or malignant lesions; Level 5 data leaves open optimal evaluation thresholds.
BACKGROUND AND OBJECTIVES: The aim of our study was to review the imaging characteristics, endocrinologic screening and histologic diagnoses of adrenal incidentaloma cases encountered in our institute. METHODS: Thirty-three adrenal incidentaloma cases that had been evaluated in Hacettepe University Hospital between 1985 and 1995 were reviewed retrospectively. Adrenal masses were discovered incidentally by abdominal ultrasonography (USG) and/or computed tomography (CT). Detailed endocrine evaluation was carried out to rule out a possible functioning mass. RESULTS: Among these incidentaloma cases, 2 silent Cushing syndrome (6.06%) cases, 6 silent pheochromocytoma (18.18%) cases, 2 adrenocortical carcinoma (6.06%) cases, and 2 metastatic masses (6.06%) were diagnosed. CONCLUSIONS: An optimal diagnostic approach to an adrenal incidentaloma would consider the results of the biochemical tests and a review of anatomical qualities depicted on CT or magnetic resonance imaging (MRI) while taking into account the previous clinical epidemiologic data.
