What is an Ovarian Dermoid Cyst?
An ovarian dermoid cyst, also known as a mature cystic teratoma, is a common type of ovarian tumor. It originates from germ cells, which are the cells that develop into eggs.
These cysts are typically benign and contain a variety of tissue types, including skin, hair, teeth, and sometimes even organs. They can range in size from a few centimeters to over 10 centimeters.
MRI findings play a crucial role in the identification and characterization of ovarian dermoid cysts. The imaging features of these cysts on MRI are distinctive and aid in accurate diagnosis.
Key MRI Findings for Dermoid Cysts:
• Presence of fat: Dermoid cysts often contain fat, which appears bright on T1-weighted MRI images and suppresses on fat-suppressed images.
• Hair and sebaceous material: These structures can be visualized as dark areas within the cyst.
• Rokitansky protuberance: A focal protrusion within the cyst that represents mucus-filled appendices testis or tubae.
• Fluid-fluid levels: Layering of fluids with different signal intensities within the cyst.
• Teeth-like structures: These structures, known as “dermoid teeth,” may occasionally be visible on MRI and are a characteristic finding.
| MRI Findings | Characteristic Feature |
|---|---|
| Presence of fat | Bright appearance on T1-weighted images, fat suppression |
| Hair and sebaceous material | Dark areas within the cyst |
