Abstract Objective: To analyze the CT imaging characteristics of children with retroperitoneal paraganglioma, combined with its pathological features, and to improve the level of diagnosis and treatment of the disease. Methods: The CT data of 4 cases(male 2, female 2) of retroperitoneal paraganglioma confirmed by pathology were analyzed retrospectively, including 1 case for CT scan+3D, the other 3 cases for scan+enhancement. Results: CT scan showed that the retroperitoneal lesions were the soft tissue density, the CT values of the tumors were 26～40 HU, the density was uneven, and the tumor diameters were 4～9.5 cm. Enhanced CT demonstrated that tumors were heterogeneous enhanced, the internal liquid necrotic areas showed no enhancement, multiple blood vessels were in and around tumors. Three dimensional reconstruction of 1 case exhibited that the boundary between cystic mass and adjacent vascular structure was not clear. Conclusion: Retroperitoneal paraganglioma is a rare tumor in children. CT scan can clearly show the size, boundary, density, blood flow, and the substance composition of retroperitoneal paraganglioma, and combined with the clinical manifestations and pathological examination can make more accurate diagnosis and treatment of the disease.
