Abstract:
Objective To study CT diagnosis and differential diagnosis of primary retroperitoneal neoplasm(PRN).Methods CT data in 23 cases of PRN confirmed by pathology were retrospectively analysed.Results There were 11 results of pathology in 23 cases,of them,14 cases were mesenchymal tissue-origin(12 cases were malignant neoplasm),4 cases were nervous tissue-origin(all benign),4 cases were rudimental embryonal tissue-origin(3 cases were benign diseases and one case was malignant),the source of unknown-origin in one case was malignant neoplasm.Most of these PRN showed such common CT manifestations as other tumors in the same location,but they had own special CT features respectively.Conclusion PRN have many typies,CT features of PRN in combination with the history,age and location can improve the diagnosis of histological classification and the diagnosis of the nature of tumors.
