  • Figure 1
    Axial T1 weighted

    Well-defined thin-walled cysts noted in both ovaries showing homogeneous T1 hyperintense signal (yellow arrows). Also note a isointense and ill-defined lesion in the posterior wall of the uterus (black star).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;
     
     
  • Figure 2
    Axial T2 weighted

    The left ovarian cyst shows mixed T2 hyper and hypointense signal (yellow arrow). Also note ill-defined hypointense lesion in posterior wall of uterus (white star).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;
     
     
  • Figure 3
    Axial T1 fat saturation

    Fat saturation images show hyperintense cysts in both ovaries (yellow arrows). Also note ill-defined isointense lesion in the posterior wall of the uterus (black star).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;
     
     
  • Figure 4
    Axial STIR

    The left ovarian cyst is completely suppressed in STIR mimicking dermoid (yellow arrow). Note ill-defined hypointense lesion in the posterior wall of the uterus (white star).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;
     
     
  • Figure 5
    Sagittal T2 weighted

    A hypointense lesion is noted in the posterior wall of the uterus distinct from the junctional zone (yellow arrow). Also note multiple tiny T2 hyperintense foci within the lesion.

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;
     
     
  • Figure 6
    Axial and sagittal T1 contrast
     

    The uterine lesion shows predominant peripheral enhancement (yellow arrow).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    The uterine lesion shows predominant peripheral enhancement (yellow arrow).
