Patient
male, 42 year(s)
 
 
  • Figure 1
    CT images of a primary presacral choriocarcinoma
     

    Unenhanced CT image showing a large presacral lesion extending to the lesser pelvis. Note the small hyperdense areas, representing hemorrhage. The air-fluis level in the urinary bladder is due to Folley insertion.

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

    CECT image showing no significant enhancement of the lesion. Note a bubble of air, suggesting infiltration of the intestine.

  • Figure 2
    T2W images of a primary presacral choriocarcinoma
     

    Axial T2W image reveals a large heterogeneous mass in the lesser pelvis, with central areas of high signal, representing necrosis.

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

    Coronal T2W image showing the heterogeneous mass.

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

    Axial T2W image with fat saturation. High signal is not suppressed.

  • Figure 3
    T1W images of a primary presacral choriocarcinoma
     

    T1W image showing a heterogeneous mass with areas of high-signal, corresponding to areas of hemorrhage.

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

    Axial contrast-enhanced T1W image showing intense enhancement of the solid parts of the lesion. Areas of necrosis are depicted as well.
