  • Figure 1
    US findings
     

    Unilateral enlarged ovary (red arrow) in right paravesical fossa, without visualizing the contralateral ovary. Note the presence of multiple small cysts (yellow arrows). BL: Bladder

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: Ultrasound; Procedure: eLearning; Special Focus: Acute;

    Unilateral enlarged ovary (>4 cm) with multiple peripheral cysts (string of pearls sign). Note the presence of free fluid around the ovary (blue arrows).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: Ultrasound; Procedure: eLearning; Special Focus: Acute;
     
     
  • Figure 2
    Colour Doppler and other findings
     

    Abscence of arterial or venous flow within the mass with some arterial Doppler flow in peripheral areas.

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: Ultrasound; Procedure: eLearning; Special Focus: Acute;

    Presence of free fluid in the right pelvis (yellow arrows). A: Iliac artery; V: Iliac vein; RA: Rectus abdominis; P: Psoas muscle.

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: Ultrasound; Procedure: eLearning; Special Focus: Acute;
     
     
  • Figure 3
    Laparoscopy
     

    Red arrows: Enlarged ischaemic left ovary. Yellow arrow: Left fallopian tube thickening. Blue arrow: Twisted ovarian branches of the uterine artery (mesosalpinx).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: Ultrasound; Procedure: eLearning; Special Focus: Acute;

    Enlarged left ovary showing a purplish color, suggesting ischaemia.

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: Ultrasound; Procedure: eLearning; Special Focus: Acute;
     
     
  • Figure 4
    Laparoscopy: Detorsion
     

    Detorted fallopian tube which appears as a thickened tubular structure (yellow arrows).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: Ultrasound-Colour Doppler; Procedure: Localisation; Special Focus: Acute;

    On US, we could visualize an enlarged left ovary (LO) in the right paravesical fossa but we were not able to see the right ovary (RO) just below.
