  • Figure 1
    Pelvic ultrasound

    Abdominal ultrasound revealed mixed echo lumps in the right part of the pelvis (1a), short clavite colour blood flow signal in the internal and blood signal (1b).

     
    Area of Interest: Lymph nodes; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    Abdomino-Pelvic CT

    Abdomino-pelvic CT showed an iso-dense mass of about 11 cm in diameter in the pelvic cavity, with punctate calcification and multiple patchy necrosis area in the centre.

     
    Area of Interest: Pelvis; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 3
    Abdomino-pelvic contrast-enhanced CT

    Abdomino-pelvic contrast-enhanced CT showed a non-homogeneous hypodense mass including variously enhanced patches scattered at arterial phase (2a). At portal phases, the degree and extent of enhancement of the tumour...

     
    Area of Interest: Pelvis; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Neoplasia;
     
     
  • Figure 4
    Pelvic MR

    MRI detected a well-defined solid mass, which was T1-hypointense (4a) and T2-hyperintense (4b).

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

Abdomino-pelvic contrast-enhanced CT showed a non-homogeneous hypodense mass including variously enhanced patches scattered at arterial phase (2a). At portal phases, the degree and extent of enhancement of the tumour gradually increased (2b).
 
MRI detected a well-defined solid mass, which was T1-hypointense (4a) and T2-hyperintense (4b).
