1. Review the wide spectrum of pediatric gynecologic masses 2. Describe imaging findings of these masses including imaging algorithm & diagnostic approach.  

Introduction Histogenesis Classification with imaging illustrations A. Gonadal 1. Tumors a. Germ cell tumors (GCTs) • Gonadal • Extragonadal (Sacrococcygeal, retroperitoneal) b. Non-GCTs • Sex cord stromal tumors • Epithelial tumors c. Miscellaneous (e.g. Metastases, PNET) 2. Non-neoplastic masses a. Ovarian torsion b. Corpus luteum cyst c. Endometriosis B. Uterocervical masses 1. Tumors [e.g. Rhabdomyosarcoma (RMS), PEComa] 2. Non-tumors (Hydrometrocolpos, Endometritis, Mullerian anomaly) C. Vaginal masses 1. Tumors (e.g. RMS) 2. Non-tumors (Hydrocolpos, Mullerian anomaly/cyst) D. Mimics (e.g. mesenchymal, desmoplastic small round cell tumors)    

"Children are not young adults". Many pediatric gynecologic masses are benign & include hydrometrocolpos, ovarian torsion, mullerian anomalies and endometriosis. One can reach the pertinent differential diagnosis by considering the age, serum markers and distinguishing imaging features of these masses. GCTs constitute majority of pediatric ovarian masses; epithelial & sex cord ovarian tumors occur mostly after age 15. RMS typically involves the vulvo-vaginal region.
