    Axial T1-weighted image shows a left adnexal mass (arrow) with a fluid-fluid level and a floating solid element (long arrow), the latter corresponding to Rokitansky nodule on histology. Parts of the lesion appear...

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Comparative studies; Special Focus: Neoplasia;

    Axial T2-weighted image depicts heterogeneous left adnexal mass, mainly of high signal intensity. Normal right ovary (arrow) and uterus (long arrow).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Comparative studies; Special Focus: Neoplasia;

    Axial fat-suppressed T1-weighted image demonstrates saturation of the hyperintense T1 components (arrow, long arrow) of the lesion, findings compatible with the presence of fat.

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Comparative studies; Special Focus: Neoplasia;

    ADC map derived from source image with b value of 1000 s/mm2 shows severely restricted diffusion of the fatty components (arrow, long arrow).
