The "waist sign” of a dilated fallopian tube

“Waist sign” refers to diametrically opposed indentations along the walls of tubular cystic structure and has been likened in appearance to a human waist (Figs. 1, 2). An adnexal cystic lesion with positive waist sign and a tubular shape is considered pathognomonic for hydrosalpinx. Hydrosalpinx is...

An adnexal cystic lesion with positive waist sign and a tubular shape is considered pathognomonic for hydrosalpinx. Hydrosalpinx is a relatively common condition that occurs when the ampullary segment of the fallopian tube becomes obstructed and the tube becomes distended by accumulated secretions. The most common cause of hydrosalpinx is sequela of prior pelvic infammatory disease, with less common causes including tubal ligation, endometriosis, and adhesions resulting from pelvic surgeries, tubal pregnancy, and tubal neoplasm
