A hydrosalpinx may be seen incidentally at CT as a fluid-attenuation tubular adnexal structure, separate from the ovary. A simple hydrosalpinx is not accompanied by pelvic inflammation. The tubal wall may enhance following contrast.
MR imaging is the modality of choice for the characterization and localization of adnexal masses that are inadequately evaluated with ultrasound. MR imaging also may be useful for determining the cause of a hydrosalpinx or its associated adnexal process by characterizing the nature of the contents of the dilated tube
