Abstract
Hydrosalpinx is a condition where the fallopian tube becomes obstructed and fills with fluid. Bilateral hydrosalpinx is most commonly associated with a pelvic infection. However, there may also be an association between partial hysterectomy and hydrosalpinx, which typically presents unilaterally. Although it is often difficult to visualize a normal fallopian tube, endovaginal sonography has proven to be a useful tool in the visualization and diagnosis of hydrosalpinx and other fallopian tube abnormalities. It is important to consider hydrosalpinx in the differential diagnosis when presented with a patient with a history of partial hysterectomy with associated pelvic pain. This case presents a woman with severe right lower quadrant pain with a history of partial hysterectomy. A pelvic sonogram revealed evidence of a unilateral hydrosalpinx. Postsurgical findings confirmed the diagnosis of right-sided hydrosalpinx and pelvic adhesions.
