- W2362945567 abstract "Objective:To improve CT detectability of abdominal neurogenic tumors.Methods:34 cases of abdominal neurogenic tumors confirmed by operation and pathological findings were studied,included neurinoma(n=16),neurofibroma (n=12),ganglioneuroma and neuroblastoma(n=6).In the total patients,there were 18 cases of benign and 16 of malignant.CT scanning was performed using 10mm slice thickness and additional enhanced CT scanning in 28 cases.Results:Most of the abdominal neurogenic tumors located in the retroperitoneal space (23/34,67.65%).The other 11 cases originated from the abdominal organs or the abdominal wall.Most of the benign neurogenic tumors showed round or oval soft tissue density shadow with smooth edges and homogenous density.Ganglioneuroma showed spotty calcification.Enhanced CT demonstrated moderate homogenous or heterogeneous enhancement of the tumor in most cases.The malignant tumors usually showed big size,irregular shape,rough edges and heterogeneous density,sometimes with necrosis,fusion or invasion to surrounding tissues.Conclusion:If the abdominal neurogenic tumors are far from the large nerve trunk,it is hard to make a nature diagnosis.The size and density of the tumor are not the characteristics in differentiation between the benign and malignant tumor.However,the rough edge,irregular shape of the tumor and invasion of the surrounding tissue are the features of the malignant neurogenic tumors." @default.
