To evaluate the frequency and appearance of uterine cavity abnormalities on Virtual Hysterosalpingography (VHSG) in comparison with Hysteroscopy in infertile patients with normal transvaginal sonography.

Forty patients being investigated for infertility and undergoing VHSG and Hysteroscopy were studied retrospectively. Twenty-six patients with previous normal transvaginal sonography were included in the analysis. The VHSG studies were performed with 64-row CT scanner (Philips Medical Systems). Findings on VHSG including single or multiple filling defects and uterine wall irregularities, were evaluated and compared with hysteroscopic results.

Twenty (77%) of 26 patients presented lesions in uterine cavity on VHSG studies. Six (13%) patients showed normal findings. Both methods (VHSG and Hysteroscopy) detected 24 lesions: 19 polyps (76%), 3 submucosal myomas (12%), 1 cesarean scar (4%) and 1 cervical synechiae (4%). Two cervical lesions (1 polyp and 1 synechiae) were detected by Hysteroscopy and not by VHSG (false negatives for VHSG). Two endometrial polyps were detected by VHSG and not by Hysteroscopy in the first look but confirmed by the second look (false negative findings for Hysteroscopy).

We observed a high prevalence of uterine cavity abnormalities in infertile patients with previous normal transvaginal sonography. VHSG results were similar to those of Hysteroscopy for the evaluation of uterine cavity pathology.

Uterine cavity abnormalities can be the cause of infertility in 10-15% of women; abnormal uterine findings occur in nearly 50% of infertile women. VHSG may have a potential role in these patients.
