Imaging of Pediatric Extragonadal Pelvic Soft Tissue Tumors: A COG Diagnostic Imaging Committee / SPR Oncology Committee White Paper

The most common pediatric extragonadal pelvic cancers include germ cell tumors, sacrococcygeal teratomas, and rhabdomyosarcomas (arising from the urinary bladder, prostate, paratesticular tissues, vagina, uterus, and perineum). This manuscript describes the radiological and nuclear medicine features of these entities and provides consensus-based recommendations for the assessment at diagnosis, during and after treatment.
