Summary
Sublingual dermoid cysts are rare floor of mouth lesions. Magnetic resonance imaging findings suggest an hourglass shape is characteristic of extended sublingual dermoid cysts.
Area of Science:
- Oral pathology
- Medical imaging
Background:
- Dermoid cysts in the floor of the mouth are classified as submental or sublingual based on their anatomical relationship to the mylohyoid muscle.
- Accurate classification is crucial for diagnosis and treatment planning.
Observation:
- A midline lesion involving the genioglossus and geniohyoid muscles was identified.
- The cyst extended superior to the mylohyoid muscle, presenting an hourglass morphology on imaging.
Findings:
- The observed magnetic resonance imaging (MRI) features, specifically the hourglass shape, are indicative of an extended sublingual dermoid cyst.
- This presentation aids in differentiating it from other floor of mouth masses.
Implications:
- Recognizing this characteristic MRI finding can improve diagnostic accuracy for sublingual dermoid cysts.
- This contributes to the understanding of rare oral cavity pathologies and their imaging features.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins the common...
