[Retroperitoneal ganglioneuroma in the infancy].

Specific management guides for suprarenal incidentalomas detected after birth do not exist for children, but due to the high proportion of malignant tumors, surgical resection is recommended. We present the case of a 7-year-old patient with a non-functioning left suprarenal incidentaloma. Surgical resection and subsequent anatomopathologic analysis of the mass confirmed the diagnosis of ganglioneuroma in process of maturation. Most ganglioneuromas are incidental and have a good prognosis due to their benign behaviour, even though malignant transformation has also been described, for which reason postoperative controls to detect local recurrence and occurrence of new foci are recommended.
