ABSTRACT

Objective To investigate the retroperitoneal ganglioneuroma ( GN) imaging findings ,and analyze its enhanced features .Methods 37 patients with retroperitoneal GN confirmed by pathology were chosen as subjects , the imaging features were analyzed and were compared with the pathologic results .All 37 cases underwent CT scan ,22 patients underwent CT enhance scan .Results 37 cases of retroperitoneal GN ,the lesions were located in the right side in 23 cases,14 cases located on the left.All lesions were demarcated,round or oval in 19 cases,18 cases of irreg-ular shape.CT scan 26 cases of 34 lesions of uniform density ,and density close to cystic lesions ,11 cases of 17 une-ven density,showed a little patchy,small strips calcification.Enhanced arterial phase lesions no enhancement ,venous phase and delayed phase showed progressive enhancement .Conclusion Retroperitoneal GN has certain characteristic imaging findings and strengthen the characteristics contribute to its diagnosis and differential diagnosis .
