In this radiology lecture, we review the ultrasound appearance of polycystic ovarian syndrome (PCOS)! • Key teaching points include: • 1) PCOS often presents with the clinical triad of oligomenorrhea and/or anovulation, hirsutism, and obesity. Associated with subfertility and recurrent pregnancy loss. • 2) Rotterdam criteria (2003) states that PCOS diagnosis requires at least two of the following: Oligo- or anovulation (ovulatory dysfunction), hyperandrogenism (clinical and/or biochemical signs), and polycystic ovarian morphology on ultrasound. • 3) Ovaries can be sonographically normal in PCOS. “Hyperandrogenic anovulation” proposed as a more accurate term. • 4) Ovaries can also appear polycystic on ultrasound without clinical diagnosis of PCOS. • 5) Rotterdam description of polycystic ovaries: 12 or more follicles 2-9 mm in size, and/or ovarian volume greater than 10 cc in at least one ovary (with no dominant cysts). • 6) Specific diagnostic cutoffs debated, and 20-25 or more follicles has been more recently (2018) suggested as a more accurate cutoff. • 7) Supportive morphologic features of PCOS include the “string of pearls sign” (peripheral location of follicles) and prominent, hyperechoic central ovarian stroma. • 8) Ovarian morphology typically more important than ovarian size, although a single enlarged, polycystic ovary sufficiently meets ultrasound criteria for PCOS. • 9) The term “polycystic” is generally incorrect and “multifollicular” has been offered as a more accurate ultrasound description, but PCOS remains the most widely used term. • 10) In post-menopausal women with new or worsening hyperandrogenism, also consider androgen-secreting tumors of ovaries or adrenal glands. • To learn more about the Samsung RS85 Prestige ultrasound system, please visit: https://www.bostonimaging.com/rs85-pr... • Click the YouTube Community tab or follow on social media for bonus teaching material posted throughout the week! • Website: https://radiologisthq.com/ • Spotify Video Podcast: https://bit.ly/spotify-rhq • Apple Video Podcast: http://bit.ly/radiologistHQ • Instagram: / radiologisthq • Facebook: / radiologistheadquarters • Twitter: / radiologisthq • Reddit: / radiologisthq
