Classifying and categorizing ovarian masses can feel like a daunting task for radiology trainees. In this episode Dr. Alan Goldstein will discuss with us his approach to these lesions to help simplify the process. First, a few mimics and pitfalls will be presented. Then Dr. Goldstein will break down the three basic types of ovarian tumors with an emphasis on imaging features:1. First, make sure the mass is truly ovarian in origin(A) Appendiceal mucocele, peritoneal inclusion cyst, hydrosalpinx, subserosal fibroid, endometrioma, metastasis2. Then break it down(A) Epithelial tumors (cystic with solid components)- Benign- Borderline- Malignant(B) Sex cord stromal tumors (solid with cystic components)- Fibroma- Other stuff(C) Germ cells tumors (bizarre masses in young patients)- Dermoid cyst- Other stuffHosts: Christopher Cerniglia, DO, ME, FAOCR.
