Ultrasound of Ovarian Serous Cystadenocarcinoma

Listen Later

In this radiology lecture, we review the ultrasound appearance of ovarian serous cystadenocarcinoma!

Key teaching points include:

  • Serous cystadenocarcinoma is the common ovarian malignancy and most common ovarian epithelial tumor
  • High-grade and low-grade types
    • Peak incidence 6th-7th decades
  • Ultrasound appearance: Mixed cystic and solid mass with papillary projections and thick septations
  • Elevated CA-125 in greater than 90%
  • Serous tumors are more commonly bilateral than other tumors
  • Four main categories of ovarian neoplasms: Epithelial (most common), germ cell (second most common), sex cord-stromal and metastases
  • Epithelial ovarian tumors are thought to originate outside the ovary (within fallopian tube or endometrium) and involve ovary secondarily
  • Epithelial ovarian tumor types: Serous, mucinous, endometrioid, clear cell and Brenner
  • 60% of epithelial tumors are benign: Unilocular with thin wall or thin septations (less than 3 mm in thickness)
  • 40% of epithelial tumors are malignant or borderline: Papillary projection (distinctive feature of epithelial tumors) with thick, irregular wall or septations (greater than 3 mm in thickness). Can also present as a large soft tissue mass with necrosis. Advanced findings include peritoneal implants, pelvic wall invasion, adenopathy and ascites
