Multi-detector row computed tomography findings of pelvic congestion syndrome caused by dilated ovarian veins.

OBJECTIVE To evaluate the efficacy of multi-detector row CT (MDCT) on pelvic congestion syndrome (PCS), which is often overlooked or poorly visualized with routine imaging examination. MATERIALS AND METHODS We evaluated the MDCT features of 40 patients with PCS (mean age, 45 years; range, 29-60 years) using axial, coronal, sagittal, 3D volume-rendered, and Maximum Intensity Projection MIP images. RESULTS MDCT revealed pelvic varices and ovarian vein dilatations in all patients. Bilateral ovarian vein dilatation was present in 25 patients, and 15 patients had unilateral dilatation. While 12 cases of secondary pelvic varices occurred simultaneously with a retroaortic left renal vein, 10 cases were due solely to a mass obstruction or stenosis of venous structures. CONCLUSION MDCT is an effective tool in the evaluation of PCS, and it has more advantages than other imaging modalities.
