The retroperitoneal tumors in children represent the majority of abdominal masses child before the age of 7 years and half between 7 and 15 years. Nephroblastoma or Wilms tumor and neuroblastoma are the most common etiologies. The aim of this study is to recall the contribution of imaging methods in the diagnosis and monitoring of retroperitoneal tumors in children. It is a retrospective study conducted over a period of 10 years (from January 2010 to December 2019), 126 benign and malignant retroperitoneal tumors, explored by ultrasound in all patients and by the abdominal CT scan in (88% of patients. All diagnostics were confirmed histologically by the examination of the surgical specimen. The average age of our patients was 8 years with a slight female predominance. We identified 75 cases of nephroblastoma (59.52%), 38 cases of neuroblastoma (30.15%), 5 cases of SRCC (3,96 %),4 cases of mesoblastic nephroma (3.17 %), 3 cases of pheochromocytoma (2.38%), and a case of malignant non Hodgkinian lymphoma (Burkitt) (0,79%). The imaging plays a vital role in the diagnosis of retroperitoneal tumors in children. Ultrasound remains the predominant method made its availability, its diagnosis and its non- radiating performance character. It allows, before the discovery of an abdominal mass, confirmed the presence of a tumor and make the differential diagnosis with other non- tumor lesions. Then comes the role of abdominal CT in second plan to confirm the ultrasound data and identify locoregional and distant as well as anatomical and vascular reporting and it also helps in cases of large tumors to determine its organ of origin and measures in the 3 spatial planes.
