Hydrosalpinx Research Paper

Hydrosalpinx represents fluid trapped in a distended fallopian tube with distal occlusion, and occurs in the setting of previous pelvic inflammatory disease. The appearance on grayscale ultrasound is of a tubular and elongated cystic mass with incomplete septations or indentations along its walls (“waist sign” or “cogwheel”)[18]. In order to fully appreciate the tubular structure of the cyst, the ultrasound probe may be turned by a 90° angle, and a seemingly simple cyst will appear to be tubular (Figure. 25). In the chronic stage, small mural nodules may be noted, resembling “beads on string”. Those typical patterns are highly suspicious for the diagnosis of hydrosalpinx

To differentiate these cysts from ovarian simple cysts it is necessary
