Adrenal Ganglioneuroma: A Case Report

Adrenal ganglioneuroma (AGN) are sympathetic differentiated tumors that originate from neural crest cells. It is a rare benign tumor in children and young adults. These lesions are usually asymptomatic and tend to be hormonally silent. Their discovery is fortuitous in imaging examinations. Preoperative diagnosis remains difficult, and the gold standard treatment is adrenalectomy. There is a good prognosis after surgery without recurrence. We herein report a case of adrenal ganglioneuroma in a 40-year-old man who benefited from an abdominal CT scan in the face of a complaint of abdominal discomfort and as part of the extension assessment of his colonic adenocarcinoma. Abdominal CT scan with contrast showed a left retroperitoneal mass of triangular shape within the adrenal lodge of tissue density, containing some calcifications not enhanced after injection of contrast product, measuring 90 x 62 mm in diameter (AP x T) with a relative washout calculated at 30%. Biopsy and histological examination of the mass suggested an adrenal ganglioneuroma.
