Ultrasound of Ovarian Serous Cystadenocarcinoma

What this episode covers

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 To learn more about the Samsung RS85 Prestige ultrasound system, please visit: https://www.bostonimaging.com/rs85-prestige-ultrasound-system-4 Click the YouTube Community tab or follow on social media for bonus teaching material posted throughout the week!
