Case of the Week: Ruptured Ectopic Pregnancy (Ultrasound) Radiology Lectures | Radquarters
-
- Medicine
In this radiology lecture, we discuss the ultrasound appearance of ruptured ectopic pregnancy.
Key points include:
* Most ectopic pregnancies occur in the fallopian tube: Ampulla most common, followed by isthmus and fimbria.
* Risk factors: Prior ectopic pregnancy, prior surgery (fallopian tube), pelvic inflammatory disease, endometriosis, IVF.
* “A single measurement of hCG, regardless of its level, does not reliably distinguish between ectopic and intrauterine pregnancy (viable or nonviable).”*
* Levels of hCG in ectopic pregnancies are highly variable.
* Tubal rupture main complication, occurs in up to 20%.
* Free fluid in pelvis alone nonspecific, but echogenic fluid in Morison pouch (subhepatic space) and cul-de-sac raises concern for rupture.
* Rupture is a relative contraindication to methotrexate (medical) therapy.
*Doubilet PM, Benson CB, Bourne T, et al. Diagnostic criteria for nonviable pregnancy early in the first trimester. N Engl J Med 2013;369:1443-51.
