Normal Tubes on Ultrasound

Fallopian tubes are on either side of the uterus attached to it near cornua and the other end is free located adjacent to ovaries.
It has interstitial, isthmic, ampullary and fimbrial parts. Interstitial end is attached to the uterus and fimbrial end is free.
Fallopian tubes vary in length from 7-12cm.
Normal tubes are usually not visualised by ultrasound.
If there is a tubal pathology like hydrosalpinx in which tubes are blocked with accumulation of fluid in it, they can be visualised on USG.
Cervix as seen on USG with a clear layer of mucus in the cervical canal is a favourable sign reflecting good level of oestrogen production.
Presence of free fluid in the pelvic cavity also can make the tubes visible.
As tubes are not normally seen on ultrasound hysterosalpingography (HSG) or Hystrerosalpingo contrast sonography (HyCoSy) is used to know the tubal patency.
Tubes are assessed during basic USG scan on 2 day or 9 day of menstrual cycle.
Few cysts like Paraovarian, paratubal cysts (cysts of morgagni) and those adjacent to uterus, vagina & superior to hymen like Gartner’s duct cyst can be seen on routine scan in some patients.
