In this radiology lecture, we discuss the ultrasound appearance of ovarian dermoid cyst, including the rarely seen but highly specific “floating sphere” sign! • Key points include: • 1) AKA mature cystic teratoma. • 2) Most common ovarian neoplasm. • 3) Benign, mean age 30. • 4) 10% bilateral. • 5) Mature tissue from ≥2 embryonic germ cell layers: Sebaceous material, hair follicles, skin derivatives, fat, muscle, bone, and other tissues lined by squamous epithelium. • 6) Specificity of US diagnosis 94-100%. • 7) MRI for changing morphology on f/u and for postmenopausal patients. • 8) Ultrasound findings: Floating echogenic spherical structures = “Floating sphere” sign (uncommon but pathognomonic), hyperechoic component with acoustic shadowing (Rokitanksy nodule), hyperechoic lines and dots, fat-fluid levels, diffuse or regional bright echoes. • 9) Most common complication: Ovarian torsion. • 10) Rare complications: Rupture, infection, malignant transformation, hormone secretion, anti-NMDA receptor encephalitis • To learn more about the Samsung RS85 Prestige ultrasound system, please visit: https://www.bostonimaging.com/rs85-pr... • Click the Community tab or follow on social media for bonus teaching material posted throughout the week! • Website: http://www.radiologistHQ.com • Video Podcast: http://bit.ly/radiologistHQ • Instagram: / radiologisthq • Facebook: / radiologistheadquarters • Twitter: / radiologisthq
