Abstract:Objective: To study the cystography and CT features of bladder rhabdomyosarcoma in children for further understanding the disease. Materials and Methods: Clinical data and imaging findings in 16 cases with bladder rhabdomyosarcoma were retrospectively analyzed. All cases had intravenous urography or cystogram, and 6 cases had CT scan. Results: Botryoidal filling defects were found in 13 cases, massive phylloid filling defects in 3 cases and rigid bladder in 6 cases in intravenous urography or cystogram. Botryoidal shadow of low-muscular density and thick-walled bladder were showed on CT scan while after the administration of contrast media the tumors were mildly or moderately enhanced. Conclusions: There are some certain radiographic characteristics in pediatric bladder rhabdomyosarcoma, we can make a correct diagnosis combining with clinical features.
