Primary adrenal ganglioneuroma: CT findings in four patients.

Abstract

The purpose of this study was to characterize the appearance of adrenal ganglioneuroma on CT scans and to define the specific imaging features of the tumor. Adrenal ganglioneuroma is an uncommon benign tumor that is revealed as a solid adrenal mass on CT scans. Specific CT features such as calcification and lesion enhancement may simulate a primary adrenal carcinoma. However, in our four patients, no signs of local invasion or vascular extension were noted. The specific diagnosis of adrenal ganglioneuroma requires either biopsy or surgical removal for documentation.
