Ruptured ectopic pregnancy

Discussion:

The differential of a spontaneous hemoperitoneum in a young female is between ruptured corpus luteum cyst and ruptured ectopic pregnancy, with the beta HCG test being an important differentiator as they can look identical on imaging studies. At surgery, a ruptured fallopian ectopic pregnancy was confirmed.

The clinical presentation was muddied by the history of trauma 2 days earlier. This led to a consensus decision, which included the patient, to do a CT despite the positive pregnancy test in order to definitively exclude solid organ or bowel injury, and to aid in the surgical planning. 

 

HISTOLOGY REPORT


Clinical history: Ruptured left ectopic pregnancy.

Macroscopic: Thin walled gestational sac with a small fetus with CR length of 22mm. Distorted fallopian tube with fimbrae measuring 75 x 15 x 15mm. An area of rupture is seen measuring 13mm in diameter.

Microscopic: Specimen is confirmed to be part of a gestational sac. Sections confirm a ruptured fallopian tube associated with chorionic villi and patchy inflammation within the fallopian tube wall. No evidence of gestational trophoblastic disease. Appearances are in keeping with the clinical history of a left tubal ectopic pregnancy.

Conclusion: Left tubal ectopic pregnancy confirmed.
