Figure 1 A 22 year-old female patient complaining of abdominal pain. Conventional MRI (a–c) showed well-defined right ovarian mixed signal intensity lesion displaying mixed high signal fatty and low signal cystic element with fat fluid intensity and suppression of signal in fat suppression denoting fat content and slight wall enhancement in postcontrast images. DWI (d and e), the lesion showing an area of restricted diffusion that showed high signal on DWI with low signal on the corresponding ADC map. ADC value of the tumor (0.92×10−3 mm2/s) for the cystic component and (1.1×10−3 mm2/s) for the solid component (conventional and DWI-MRI): benign looking right adnexal cystic lesion likely dermoid. Pathology showed mature cystic teratoma (benign germ cell tumor). Mature cystic teratoma showed restricted diffusion may be attributed to keratinoid substance and Rokitansky protuberance. DWI, diffusion-weighted imaging.
