Patient
female, 16 year(s)
 
 
  • Figure 1
    Abdominal US
     

    a) Axial plane abdominal-US shows a large and well defined cystic lesion

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

    b) Right oblique sagittal plane abdominal-US depicts right hydronephrosis

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Cysts;
     
     
  • Figure 2
    Portal phase CT
     

    a) Portal phase CT showing the cystic lesion extending cranially over the bladder (arrow) through the 5th spinal vertebra level. Uterine fundus (arrowhead).

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

    b) Portal phace CT confirms right hydronephrosis.

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

    c) CT portal phase. Axial plane; a well-defined the homogeneous cystic lesion presents homogeneous hypodense content. Left and right ovaries are seen (arrows)

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Cysts;
     
     
  • Figure 3
    Pyelographic phase
     

    a) Pyelographic phase. Axial plane. No CE can be seen in the cyst. The right ureter is dilated (arrow)

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

    b) CT Pyelographic phase. Coronal plane. Right hydronephrosis is clearly appreciated

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Cysts;
     
     
  • Figure 4
    T2WI MRI
     

    a) Axial T2WI MRI shows a unilocular thin-walled cyst with smooth margins. The left ovary with some small follicles (arrow) can be appreciated

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

    b) Axial T2WI MRI image shows the left ovary stretched and dislocated laterally by the lesion (arrow)

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

    c) Saggital T2WI MRI. The left ovary (arrow) is seen. There are no MRI imaging features of malignancy

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

    d) Coronal T2WI MRI. Left ovary (arrow heads)
