From: Mature cystic teratoma of the ovary: a cutting edge overview on imaging features
Axial T1-weighted (a), diffusion-weighted (b 800) image (b) and ADC map (c) images of a 22-year-old female with a mature cystic teratoma (same case as in Fig. 21). A hypointense cauliflower-like mass is seen near the interface of the fat-fluid level and a Rokitansky nodule is seen in the posterior part of the cystic lesion (a). The cauliflower-like mass shows diffusion restriction regarding the keratin content (b, c). Whitish cheese-like material regarding keratin (arrows) is seen in the lumen in the macroscopic specimen of the tumour (d). Cut section of the Rokitansky nodule (arrowheads) shows a yellowish fat component, creamy keratin and fine hair shafts arising from the nodule
