Adrenal neuroblastoma (ANB) originates from neural crest cells in the adrenal medulla and is rare in adults, with fewer
than 10% of cases occurring after age 14 and with a prevalence of about 0.12 per million. Clinical presentations are
nonspecific, often including abdominal pain or mass, leading to delayed diagnosis. Imaging typically shows a
heterogeneous adrenal mass. Due to its rarity, adult cases are treated using paediatric protocols. ANB is highly
aggressive and carries a poor prognosis in adults. This report describes a 17-year-old male with a large ANB,
successfully treated with radical surgical resection and chemotherapy, followed by an uneventful recovery.
