Ultrasound :Typically an ovarian dermoid is seen as a cystic adnexal mass with some mural components. Most lesions are unilocular. The spectrum of sonographic features includes: diffusely or partially echogenic mass with posterior sound attenuation owing to sebaceous material and hair within the cyst cavity an echogenic interface at the edge of mass that obscures deep structures: the tip of the iceberg sign mural hyperechoic Rokitansky nodule (dermoid plug) echogenic, shadowing calcific or dental (tooth) components the presence of fluid-fluid levels 5 multiple thin, echogenic bands caused by the hair in the cyst cavity: the dot-dash pattern (dermoid mesh) color Doppler: no internal vascularity internal vascularity requires further workup to exclude a malignant lesion intracystic floating balls sign is uncommon but characteristic .
