Image Description
Ganglioneuromas usually present as large masses in the posterior mediastinum (40% of cases) or retroperitoneum (30% of cases). Although adrenal involvement is comparatively less common (20% of cases), they must be considered during the evaluation of an adrenal mass. The image shows a thin rim of stretched out adrenal cortex overlying the tumor. The tumor is well-circumscribed and contains a fibrous capsule.
