Patient
female, 62 year(s)
 
 
  • Figure 1
    MRI - Invasive scamous cell carcinoma of the cervix
     

    T2-weighted axial image. There was no extension of the cervical mass to the bladder or the rectum.

     
    Area of Interest: Pelvis; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Sagittal T2-weighted image depicts tumor extension to the upper third of the vagina (arrow). The neoplasm has signal intensity similar to that of normal myometrium.

     
    Area of Interest: Adrenals; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Post-gadolinium T1-weighted sagittal image shows better discrimination of tumor margins (arrow). The neoplasm enhances less than normal myometrium.

     
    Area of Interest: Kidney; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Congenital;
     
     
  • Figure 2
    MRI - Pelvic anomaly
     

    Transaxial T1-weighted MRI shows an abnormal structure in right side of the pelvis.

     
    Area of Interest: Pelvis; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Sagittal T1-weighted image shows the extent of this structure better, with morphological characteristics of a kidney.

     
    Area of Interest: Pelvis; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Transaxial T2-weighted images confirms an aspect compatible with kidney tissue.

     
    Area of Interest: Pelvis; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Congenital;
     
     
  • Figure 3
    Pre- and post-contrast (corticomedular phase - 1min) Pelvic CT
     

    Pre-contrast axial CT only shows a pelvic mass lateralised to the right.

     
    Area of Interest: Pelvis; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Pre-contrast coronal reconstruction shows both kidneys better, fused together in right side of the midline, in the pelvic cavity.

     
    Area of Interest: Pelvis; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Pre-contrast sagittal reconstruction.

     
    Area of Interest: Pelvis; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Post-contrast axial CT. The kidneys do not exhibit focal suspicious lesions, pyelocalicial dilatation or perirenal anomalies.

     
    Area of Interest: Pelvis; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Contrast-enhanced coronal reconstruction CT shows fused right and left kidneys which also failed to ascend representing bilateral fused pelvic kidneys.

    Post-contrast sagittal reconstruction.
