"post-hysterectomy (without salpingo-oophorectomy)"
"distinct from the uterus and ovary."
"Signal characteristics of the dilated tube(s) include:"
"cystic ovarian neoplasm(s): identification of a separate ovary helps distinguish a hydrosalpinx from a cystic ovarian mass, an important distinction because malignancy is rare with an extraovarian cystic adnexal mass"
"T1: typically hypointense although can be hyperintense if there is proteinaceous fluid"
"T2: hyperintense"
"T1 C+ (Gd): the mucosal plicae and the tube walls may show mild enhancement"
"Longitudinal folds in a normal fallopian tube may become thickened in the presence of a hydrosalpinx. The folds may produce a characteristic “cogwheel” appearance when imaged in cross-section. These folds are pathognomonic of a hydrosalpinx. Indentations on the opposite sides of the wall are referred to as the waist sign, which strongly predicts hydrosalpinx. The waist sign, in combination with a tubular-shaped cystic mass, has been found to be pathognomonic of a hydrosalpinx 9. Incomplete septa may also give a "beads on a string" sign."

"Hydrosalpinx is a descriptive term and refers to a fluid-filled dilatation of the fallopian tube. If the fluid is infected, i.e. pus, then it is a pyosalpinx; if bloody, then haematosalpinx."
