Giant Adrenal Neuroblastoma in Adults: Surgical Management and Comprehensive Review.

Neuroblastoma (NB) is a rare solid tumor of the sympathetic nervous system, primarily occurring in children and rarely in adults. Its extracranial origin stems from the medullary region of the adrenal gland or sympathetic ganglia. We report an 18-year-old female who presented with a 6-month history of abdominal swelling and tenderness. Imaging revealed a large retroperitoneal mass causing significant displacement of adjacent structures. Following multidisciplinary optimization, a huge tumor was successfully resected surgically. Histopathology confirmed the diagnosis of adrenal NB. The patient underwent adjuvant chemotherapy and remained symptom-free with favorable outcomes during a 9-month follow-up. This case underscores the importance of comprehensive diagnostic evaluation and multimodal management in treating rare adult adrenal NB.
