Multimodality imaging of ovarian cystic lesions: Review with an imaging based algorithmic approach

Figure 10 Mature cystic teratoma. A 51-year-old woman with pelvic mass and constipation. (A) Transvaginal ultrasonography demonstrates a complex cystic mass in the right ovary with septations and solid component, causing posterior acoustic shadowing (arrowhead) suggesting calcification. Axial precontrast T1 weighted image of the pelvis without fat saturation (B), post contrast T1 weighted image with fat saturation (C) and sagittal T2 weighted image though the pelvis (D) demonstrates a left ovarian complex mass with cystic component (arrow) showing mild to moderate low signal intensity on T1 weighted image and high signal intensity on T2 weighted image. Hyperintense foci on T1 weighted image with signal loss on T1 fat saturation (thick arrow) representing fat content, T1 and T2 hypointense foci representing calcific foci (arrowhead). Ut: Uterus.
