Incidentally discovered well-differentiated retroperitoneal liposarcoma with inguinal canal herniation: report of 2 cases

Figures

• 

  Fig. 1. Baseline axial CT shows right ureteral stone (A) with distention of the ipsilateral ureter (B, white arrow). CT also shows the presence of a partially adipose retroperitoneal mass located in the left iliac region. Coronal (C) and sagittal (D) CT showing the retroperitoneal mass herniated through the left inguinal canal to the ipsilateral scrotal region. CT, computed tomography.

• 

  Fig. 2. Axial (A and B), coronal (C), and sagittal (D) CT images after contrast medium administration, showing soft-tissue component and foci and septa of contrast enhancement. Abdominal evaluation did not reveal other organs abnormalities. CT, computed tomography.

• 

  Fig. 3. Contrast-enhanced CT (A-C) shows the presence of a giant retroperitoneal capsulated, mainly adipose, mass with thin septa and some nodular foci with early contrast enhancement. This lesion presents herniation in the left inguinal canal. CT, computed tomography.

• 

  Fig. 4. Axial and coronal contrast-enhanced CT showing displacement of the aorta (A and B), of the colon (C, black arrow), of the sigmoid colon, of the bladder and of the left ureter (D, white arrow) which results regularly pervious. CT, computed tomography.

  Fig. 5. Surgical images show resection of the mass and the surgical specimen.
