Background: Ganlioneuroma is a rare, benign, neurogenic tumor originating from the neural sheath and frequently localized in the retroperitoneum.
Aim: Report of a new case.
Case: We report a case of a 36-year-old woman presenting isolated right lumbar pain. Computed tomography revealed a heterogeneous, right, retroperitoneal mass, 13 cm in diameter. Complete resection of the tumor and right nephrectomy were performed. Histology confirmed the diagnosis of ganglioneuroma. Follow-up was 10 months with no recurrence. Through this case, we discuss diagnostic, therapeutic and prognostic aspects of this disease.
