Abstract：【Objective】To explore the CT imaging features of rhabdomyosarcoma in the pelvic and urogenital tracts of children.【Methods】A retrospective analysis was conducted on the imaging and clinical data of children admitted to our hospital from January 2017 to December 2022 who were pathologically confirmed as rhabdomyosarcoma after surgery. All patients underwent plain and enhanced CT scans to analyze the CT imaging features and pathological examination results of the tumor.【Results】All 15 cases of pediatric lesions in this group were located in the pelvic cavity and reproductive tract,with 5 cases occurring in the trigone of the bladder,2 cases in the testicles,3 cases in the pelvic cavity,5 cases in the perineum,and 2 cases with metastasis. The solid density of the tumor is lower than that of the muscle,and the enhanced scan shows uneven enhancement,delayed enhancement,and multiple new blood vessels around it,without any calcification,fat,or bleeding changes.【Conclusion】Rhabdomyosarcoma of the pelvic and urogenital tracts in children has certain CT imaging features and can be differentiated from other malignant tumors,but the final diagnosis requires pathological biopsy.
