Computed Tomography Ectopic Implantation

Computed Tomography imaging findings of a 37-year-old woman with interstitial pregnancy.[1] Showing initial CT detection and a subsequent scan following rupture causing a hematoma around uterus and a massive hemoperitoneum.

Magnetic Resonance Imaging Abdominal Ectopic Implantation

2W SPAIR sagittal MRI of lower abdomen demonstrating the placental invasion.[2]
  • Placenta was attached tightly to the mesentery of sigmoid colon and was loosely adhered to the left abdominal sidewall.
  • The fetus was localized at the right of the abdomen and was related to the placenta by a cord.

Tubal Ectopic Pregnancy

Chlamydia infections (Chlamydia trachomatis) are the most common bacterial sexually transmitted infection, often undiagnosed and asymptomatic. The infections can ascend the female genital tract, colonizing the endometrial mucosa, then the uterine tubes. This type of infection is described as pelvic inflammatory disease (PID).

Interstitial Pregnancy

(cornual pregnancy) A less common type 2 to 4% of ectopic pregnancies. The gestation develops in the uterine portion of the fallopian tube lateral to the round ligament.

Ovarian Ectopic Pregnancy

  • u - normal aspect of the uterus.
  • t - left fallopian tube.
  • e - ruptured ectopic pregnancy in the left ovary.

Cervical Ectopic Pregnancy

Cervical Ectopic Pregnancy Ultrasound[6]

This form of ectopic pregnancy is a rare high-risk condition and represents less than 1% of all ectopic pregnancies. The reported incidence varies between 1:1,000 to 1:18,000.

Rudimentary Horn Pregnancy

A rare types of ectopic pregnancy (about 1 in 76,000 pregnancies) in most cases the horn is non-communicating. Therefore fertilisation probably occurs by transperitoneal migration. This form untreated can also lead to uterine rupture.

Caesarean Scar Pregnancy

A rare types of ectopic pregnancy (about 1 in 2000 pregnancies), but probably increasing as caesarean rates rise. The gestation is completely surrounded by both myometrium and fibrous tissue of the caesarean section scar and separated from the endometrial cavity and endocervical canal.
