Ultrasound of Interstitial Ectopic Pregnancy
In this radiology lecture, we review the ultrasound appearance of interstitial ectopic pregnancy!
Key teaching points include:
1) Interstitial ectopic pregnancies are rare, occurring in proximal (interstitial) portion of fallopian tube within muscle wall of uterus
2) Much less common than tubal ectopic pregnancy occurring in the more distal ampullary and isthmic portions of fallopian tube
3) Interstitial ectopic pregnancies are important because higher morbidity and mortality due to risk of life-threatening hemorrhage
4) Abnormally eccentric gestational sac with thin surrounding myometrium: less than 5 mm myometrial thickness highly suspicious
5) “Interstitial line” sign: Thin echogenic line extending from endometrial cavity to ectopic gestational sac. Thought to represent interstitial portion of tube separating the ectopic pregnancy from the endometrium
6) Medical: Systemic MTX, may also be injected into sac
7) Surgery: Cornual wedge resection when ruptured versus hysterectomy
8) Can be confused with angular pregnancy: Rare, intrauterine pregnancy with implantation eccentrically high at the lateral angle of uterine cavity. More medial than interstitial ectopic pregnancies. No interstitial line sign, and greater than 5 mm thickness of overlying myometrial mantle
9) Angular pregnancy can result in normal pregnancy, but increased risk of miscarriage and uterine rupture. Should be followed closely to ensure growth towards endometrial cavity
10) Angular pregnancy is sometimes referred to as a “cornual pregnancy,” but controversial as earliest use of term cornual pregnancy refers to intrauterine implantations in anomalous unicornuate, bicornuate or septate uteri. To avoid confusion, best to specifically describe whether the gestational sac is intrauterine or ectopic

Hello sir, how much volume of contrast and flow rate should be followed in hepatic protocol
Excellent presentation. If possible a video could be made comparing Hepatic Abcess and Hydatid Disease.
Super.thank you
You're welcome, glad you enjoyed it!

Thank you!
Briliant, many thanks!
Glad you enjoyed it!
Briliant style and love the quick review at the end!
Thank you!
Beautiful! Amazing how clearly the 3D Imaging delineates the location of the gestational sac as compared to 2D in this case.
Agreed, the 3D is very helpful!
thanks sir 😊
You are most welcome!
Great one! Thanks
Welcome!
This was helpful and clear. Thank you!
Great to hear, and thanks for watching!
Thank you for sharing. Always so educational.
Thank you, appreciate that!
@@Radquarters would you suggest any resources for obstetrics and gynecology scans?
@@johnweak3198 Ultrasound: The Requisites is an excellent book, and one I recommend for my students.
@@Radquarters thank you very much!
very nice
Thank you! Appreciate that
Ultrasound while lying can identify varicocele?
Yes, particularly if Valsalva is used, but standing position often helps with diagnosis.
Very nice ultrasound .which model used
Thanks! These images were obtained on a Samsung RS85 Prestige unit: www.bostonimaging.com/rs85-prestige-ultrasound-system-4
I get it that you are really smart and stuff but it takes a real smart person to be able to dumb it down so regular people can understand what the f*** you're talking about
Can we do it in ge 16 slice machine.. we don't get this kind of scan ..our del ded is 8
Yes, a multiphase liver scan can be performed with a 16 slice scanner.
@@Radquarters yes sir but we r not getting proper arterial phase our scan del sec is 7 to 8 sec
@@jeevnasam4810 You might want to consider a delay closer to 35 seconds for the late hepatic arterial phase. 7-8 seconds is typically closer to a true arterial phase (i.e., hepatic artery enhancement with no portal venous enhancement).
Great presentation.. thanks from India.
Glad you liked it, and hello to India!
Great work! 😀
Thank you!
Great video. Thank you, and keep up the excellent work. I appreciate it 😀

Beatutiful film! May i know frequency working probe? thanks
Thank you! For wrist ultrasounds, I tend to use a combination of a 2-14 MHz and a 4-18 MHz linear transducers. A hockey stick (3-22 MHz) can also be helpful for more focused evaluation (ligaments, nerves).
@@Radquarters thank you so much
Great👏👏👍👍
Thank you!
Thanks for knowledge on it
Sure thing
Hi Should testes ultrasound be conducted with the patient standing or supine? I had a physical examination and my GP suspects varicocele, but my testes ultrasound showed no varicocele.
Scrotal ultrasounds are usually performed in supine position, but for varicocele the standing position is sometimes added.
Superb presentation 🎉
Thanks so much!
Hello ...dose this infection epididymitis orchitis damage the microtubes from the epididymis? it seems nobody talks about this posible trauma after the infection is over
Good question! Tubular ectasia of the rete testis can occur in the post-inflammatory setting. Also, depending on the severity and duration of epididymo-orchitis, both the epididymis and testis can develop heterogeneous parenchyma +/- calcifications.
My situation right now..am so stressed
Amazing video!
Thanks Talia Cheng, appreciate that!
Thanks. Very nice video.
Thank you, appreciate that :)
Very good example! Although I think you should explain that parathyroids can be located in many places including intrathyroid, and because of that we can speak about parathyroid change in the thyroid. Also lack of TiRADS which should be 4 in this case. A plus for typing what US system you use, a top one.
Thank you, and excellent points! However, I do actually describe the ectopic locations of parathyroids at time 3:58 in the video, and also that they can mimic TI-RADS 4 nodules at 4:14.
@@Radquarters I missed it somehow, my fault, forgive me, do you perform echocardiography as well?
@@adamguszak7050 No problem, and thanks for watching. I don't perform echocardiography. Sorry!

High quality images, Can you tell me the Program or application you use to Record your nice videos?
Sure, I make the presentations using PowerPoint, then I record and edit using ScreenPal. I also use a Blue Yeti mic.
