CT Evaluation of Primary Retroperitoneal Tumors / 实用放射学杂志

ABSTRACT

Objective To discuss the CT features of primary retroperitoneal tumor(PRT) ,so that to improve the knowledge of these diseases.Methods 24 cases with PRT confirmed by surgery and pathology were assessed retrospectively,and their CT manifestations were analyzed in comparison with pathology. Results All cases included8 cases of liposarcoma with predominant fat components, 2 cases of fibrosarcoma with evident involvement of adjacent tissues,2 cases of leiomyosarcoma with multiple centers fused, 4 cases of schwannoma localized at paraspine and cystic generation commonly,1 case of ganglioma with hypodense parenchyma,1 case of neuroblastoma with large calcification, 1 case of paraganglioma and 2 cases of chemodectoma and enhanced obviously,1 case of pheochromocytoma enhanced evidently with cystic generation ,1 case of neuroendocrinoma without specific characteristic and 1 case of teratoma with 3 layers of embryo tissues. Conclusion CT acan is able to localize the primary retroperitoneal tumors accurately,but specific CT features only see in some cases.
