Abstract:
Objective To investigate the clinical and CT features of non-epithelial malignant tumors of bladder to improve the understanding.Methods Clinical and CT data of 1 1 patients with non-epithelial malignant tumors of bladder were analyzed retrospectively. All patients underwent plain and contrast enhanced CT scan,and confirmed by surgery and pathology.Results Of 1 1 patients,there were 4 rhabdomyosarcomas,3 cancerous sarcomas,2 leiomyosarcomas and 2 small cell carcinomas.The CT performance were mostly cauliflower like or papillary,with wide basis and thickening of adjacent bladder wall.Diffuse thickening of the bladder wall was detected in all rhabdomyosarcoma lesions.The lesions were homogeneous or heterogeneous soft tissue-like density.CT showed calcification in 1 cancerous sarcoma,necrosis in 1 leiomyosarcoma and 1 rhabdomyosarcoma.Contrast enhanced scan showed mild to moderate or significant enhancement.Conclusion Besides the age of rhabdomyosarcoma,other non-epithelial malignant tumors of bladder have no special clinical and CT characteristics.CT examination can provide the information about location,size,surrounding tissue change,which is helpful to make the treatment plan.
