Patient
female, 26 year(s)
 
 
  • Figure 1
    Abdominal US

    Longitudinal sonogram of the pelvis shows a marked hypoechoic solid lesion (arrow), posterior to the uterus.

     
    Area of Interest: unknown; Imaging Technique: Abdominal US;
     
     
  • Figure 2
    Transvaginal US
     

    This sonogram displays a well-defined, hypoechoic moderately heterogeneous solid lesion, with a small central cystic area and posterior enhancement. It measures 7cm x 5.4cm.

     
    Area of Interest: unknown; Imaging Technique: Transvaginal US;

    The lesion is partially seen here, adjacent to the right ovary.

     
    Area of Interest: unknown; Imaging Technique: Transvaginal US;
     
     
  • Figure 3
    Gross specimen

    Tumour section: encapsulated tumour with haemorrhagic foci, measuring 8cm in the longest axis.

     
    Area of Interest: unknown; Imaging Technique: Gross specimen;
     
     
  • Figure 4
    Photomicrograph (H & E, 40X)

    The tumour was composed of alternating areas of compact cells (Antoni A areas) and less cellular zones presenting a loose matrix (Antoni B areas), a pattern consistent with a diagnosis of schwannoma.
