Right patent fallopian tube.
Left fallopian tube could not be demonstrated beyond the corneal portion.
Intravasation of contrast into the myometrial vessels and subsequently into pelvic veins.
Intravasation on HSG is characterized by opacification of the myometrial vessels (mostly veins) which appears as fine lace-like network or reticular pattern surrounding the uterine cavity and followed by drainage into the larger pelvic veins.
Intravasation may indirectly indicate tubal occlusion as it has been postulated that tubal occlusion might be associated with intravasation due to increasing intra-uterine pressure.
Intravasation is one of the pitfalls which can mimic intraperitoneal spillage in an occluded fallopian tube.
Another differential diagnosis can be uterine perforation but they usually occur as a result of any intra-uterine procedure or implantation.
