Abstract:
Objective To analyze the MSCT features of subepithelial lesions of the urinary bladder.Methods Thirty-one patients with subepithelial lesions of the urinary bladder proved by pathology were enrolled in this study.The MSCT findings were analyzed. Results Among the 3 1 cases with subpeithelial lesions of the urinary bladder,7 cases were non-epithelial tumors (including 3 cases of leiomyomas,2 cases of paragangliomas,1 case of hemangioma and 1 case of granulocytic sarcoma),and other 24 cases were inflammatory/reactive lesions,all as cystitis glandularis.MSCT findings were as follows:paragangliomas were solitary masses with homogeneous density,smooth border and wide base,with rapid wash-in and wash-out enhancement pattern and peak enhancement in the arterial phase.Hemangiomas and leiomyomas both presented as single round mass with slight enhancement.Granulocytic sarcoma appeared as diffuse bladder wall thickening with pebble-like projections,and slight enhancement.Cystitis glandularis was characterized by local thickening of the bladder wall with nodular or aquatics-like uplift,and was also characterized by diffuse thickening,with slight and progressive enhancement in 22 cases,and significant enhancement in venous phase in 2 cases.Conclusion The subepithelial lesions of urinary bladder may present with tumor-like appearance.The key characteristic feature for cystitis glandularis is local thickening of the bladder wall with nodular or aquatics-like uplift.Rapid wash-in and wash-out enhancement pattern is considered to be diagnostically significant for paragangliomas.However,the rest of the lesions overlap in the imaging appearances,and the diagnosis should be combined with clinical manifestations to improve the accuracy of preoperative diagnosis.
