- Abstract
Uniform circumferential bladder wall thickening is almost always due to benign disease, with the differential diagnosis including any type of cystitis, neurogenic bladder, and chronic mechanical bladder outlet obstruction. An axial portal venous phase contrast-enhanced CT image through the pelvis in a patient who had undergone transurethral resection of a bladder tumor and topical treatment with BCG 6 months earlier demonstrates marked asymmetric thickening of the bladder wall on the left side laterally and anteriorly (arrow). On CT urography, affected patients usually present with diffuse circumferential bladder wall thickening [[20]], although a minority will have asymmetric areas of bladder wall thickening that mimic urothelial neoplasms (Fig. An axial portal venous phase contrast-enhanced CT image through the pelvis in a patient who had had a transurethral resection of a bladder tumor followed by topical mitomycin therapy demonstrates the bladder wall to be irregularly thickened, with lobulated mass-like thickening particularly along the right lateral and anterior walls (arrows). Coronal imaging can be helpful to localize the abnormality. b An axial portal venous phase contrast-enhanced CT image through the pelvis in a different female patient with incontinence demonstrates high attenuation material in a crescentic shape in the periurethral region, consistent with the carbon-coated bead type of bulking agent. c A coronal image from this same female patient's CT helps localize the agent.
