Primary adrenal ganglioneuroma: CT findings in four patients.

Abstract

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.
