From: Mature cystic teratoma of the ovary: a cutting edge overview on imaging features
Axial T1-weighted MR image of a 31-year-old female with mature cystic teratoma (a) shows high signal intensity of the supernatant fatty layer creating an interface with a low signal intensity aqueous layer. Fat-saturated T1-weighted image (b) demonstrates a major fat component with decreased signal intensity in the supernatant layer and free-floating hypointense fat particles in the aqueous layer. A Rokitansky nodule with cystic components is seen in the posterior part of the cyst. Cut section of the tumour (c) shows yellowish sebaceous material leaking from the cystic lumen. Note the black hairs in that material
