Sonographic detection of rhabdomyosarcoma of the urinary bladder.

ABSTRACT

Rhabdomyosarcoma (RMS) is the most common malignant pelvic tumor in the young child, occurring typically in children aged 2-4 years. It arises from the prostate or the trigone of the bladder in boys, and from the vagina or uterus in girls. We report a case of bladder rhabdomyosarcoma and discuss the ultrasonographic images. The mass produced filling defect on the contrast cystogram and also was demonstrated with CT.
