Report of 66 cases of adrenal incidentalomas

Abstract

Objective To investigate the clinical features,diagnosis and therapy of adrenal incidentalomas. Methods The data of 66 cases of adrenal incidentalomas were retrospectively analyzed. Results The accuracy rates of localization detected by B-Ultrasound,CT scan and MRI were 84.3%,100% and 100% respectively. The accuracy rates of qualitative diagnosis by B-Ultrasound, CT scan and MRI were 30.0%,75.5% and 79.2% respectively. There were 60 cases underwent operation and the postoperative pathological examination confirmed that there were 31 cases of adrenal cortical adenoma, 6 cases adrenal cyst, 5 myelolipoma, 5 pheochromocytoma, 3 adrenal cortical carcinoma, 3 metastatic carcinoma, 3 ganglioneuroma, 1 adrenal neurilemmoma, 1 adrenal hematoma, and 1 nodular hyperplasia of adrenal cortex. Conclusions Ultrasonography is the first choice of scanning adrenal incidentaloma. However the CT scan and MRI are satisfactory in localization of the tumour. The qualitative diagnosis of adrenal incidentaloma will depend on the diameter, imaging features of tumors, the age of patients, and endocrine examination. Key words: Incidentaloma; Adrenal tumor
