case_images: Duplex ultrasound of suprapubic venous plexus. Note the tortuosity in the vessel and the continuous flow beneath the ultrasound probe.

case_images: However, Doppler waveforms show continuous forward flow in the large subcutaneous venous plexus, Figure 1.
case_images: Axial MRI of pelvis with contrast showing large suprapubic varicosities (white arrows) and a small right external iliac (short arrows). The left external iliac vein is larger (long arrows).

case_images: Magnetic venous imaging was obtained to evaluate pelvic and intra-abdominal varices and to better characterize the feeding and outflow vessels.  Figure 2 demonstrated large subcutaneous varicosities and a diminutive right external iliac vein compared to the left iliac vein.
case_images: MRI with contrast demonstrating abnormal iliac fossa varicosities (a) Conventional right femoral venogram demonstrating large right to left cross pelvic collaterals to the left femoral system (b).

case_images: The reformatted MRI with Gadolinium, Figure 3(a), demonstrated the subcutaneous plexus and the collateral flow from right femoral system to the left femoral system via these enlarged cross-pelvic collaterals. The subsequent diagnostic conventional venogram is seen in Figure 3(b).
