In this radiology lecture, we review the ultrasound appearance of sublingual dermoid cyst and explain floor of mouth anatomy! • Key teaching points include: • 1) The floor of the mouth is a horseshoe-shaped area beneath tongue and in between sides of mandible, inferiorly bounded by mylohyoid muscle, and containing sublingual space (SLS) • 2) SLS medial border: Midline genioglossus/geniohyoid muscle complex; SLS inferolateral border: Mylohyoid muscle • 3) Anterior margin of hyoglossus muscle projects into posterior SLS • 4) Sublingual dermoid cyst is a rare, benign cyst with squamous epithelial lining and contains skin appendages • 5) Dermoid and epidermoid cysts are in same family, terminology often used interchangeably although epidermoid cysts less common and tend to contain fluid contents only • 6) Dermoid cyst mean age of presentation late teens to twenties, average age 30 • 7) Presents as a slowly enlarging neck mass, may cause dysphagia • 8) Often round or oval in shape and homogeneously hypoechoic with punctate echogenic foci • 9) May have pathognomonic “sack of marbles” appearance • 10) Relationship to mylohyoid is key for surgical planning: Intraoral resection for sublingual (above mylohyoid) location, extraoral approach for submental/submandibular (below mylohyoid) location • 11) Most cysts are midline • 12) DDx: Suprahyoid thyroglossal duct cyst, ranula (simple and diving), abscess and lymphangioma • 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://Radquarters.com/ • Spotify Video Podcast: https://spoti.fi/462r0F2 • Apple Video Podcast: https://apple.co/3ZhHuGu • Instagram: / radquarters • Facebook: / radquarters • X (Twitter): / radquarters • Reddit: / radiologisthq
