Which condition is defined by a thick, complex endometrium with retained products of conception?

• A. Incomplete abortion
• B. Ectopic pregnancy
• C. Anembryonic pregnancy
• D. Subchorionic hemorrhage

Answer: (A)

Retained products of conception after a miscarriage or abortion lead to incomplete abortion. On ultrasound, this shows as a thick, irregular endometrial canal filled with echogenic material representing tissue, which may also display vascularity with Doppler. The presence of intrauterine tissue that remains after an attempted or completed abortion is the hallmark of incomplete abortion. This differs from ectopic pregnancy, where there is little or no intrauterine content and you may see an adnexal mass or free fluid. Anembryonic pregnancy presents with a gestational sac in the uterus but no embryonic tissue. Subchorionic hemorrhage appears as a bleed around the gestational sac, not as retained intrauterine tissue with a thickened, complex endometrium.
