Abstract

Venous aneurysm, especially of primary origin, is rare. The authors report a case of a 63-year-old female who was admitted for back pain and an aneurysm of the common iliac which was detected incidentally. CT, magnetic resonance (MR), Doppler ultrasonography, and conventional venography showed an aneurysm of the left common iliac vein measuring 4.5 x 3 x 4 cm. Because there were no complications of the aneurysm, no further treatment was administered. Herein, we describe findings of a venous aneurysm of the common iliac vein mimicking a pelvic mass on CT and MR scans and with a review of the literature.

  Fig. 1 A 63-year-old female with a venous aneurysm of the common iliac vein. A. Abdominopelvic CT scans (upper image in non-enhanced scan, middle and lower images in portal and delayed phases, respectively) show heterogeneous enhancement of the tumor (asterisks) relative to the common iliac vein (arrows). B. T1-weighted axial scan (upper image) shows a hypointense mass (arrows) relative to muscle and common iliac vein. T2-weighted scan (lower image) shows a hyperintense mass with central hypointensity. C. T1-weighted coronal scan with contrast enhancement shows the same enhancement of the tumor (arrow) compared with the common iliac vein. D. Sonography with color doppler shows blood inflow to the aneurysm (An) and aneurysmal neck (arrow). E. Early (right image) and late (left image) phases of venogram show contrast filling in the aneurysm (arrows) on the anteromedial aspect of the left.
