Ruptured dermoid cyst. High T1 signal material is floating on CSF in the anterior horns of the lateral ventricles (blue arrows), and multiple small droplets of T1 hyperintense material can be seen in the subarachnoid space of both hemispheres (yellow arrows). http://radiopaedia.org/articles/intracranial-dermoid-cyst-1
Sublingual Dermoid Cyst: Fig 3a, b and c: T1W axial (3a), T2W axial (3b) and T2W sagittal (3c) MRI scans show well circumscribed mass lesion sharply circumscribed cystic mass lesion in floor of mouth, displacing mylohyoid muscle inferiorly, which appear hypointense on T1W + hyperintense on T2W images. T2-weighted MRI image shows characteristic appearances of midline dermoid cyst in floor of mouth w “sack of marbles” appearance due to presence of fat globules (arrowheads) within dermoid…
Well formed teeth visible in a mature cystic teratoma(dermoid cyst) of the ovary. The tissues of a teratoma, although normal in themselves, may be quite different from surrounding tissues and may be highly disparate; teratomas have been reported to contain hair, teeth, bone and, very rarely, more complex organs or processes such as eyes,torso, and hands, feet, or other limbs.

- Ultrasound features of dermoid cysts. (A) Rokitansky nodule with a strong acoustic shadow. (B) Acoustic shadows and bright echoes representing hair in the cyst. (C) Unusual but interesting presentation of a dermoid cyst which has been described as ‘floating balls’ - secondary to hyperechoic intracystic fat balls.
