There may be a variable degree of associated myometrial thinning and obliteration of the junctional zone. MRI appearance is variable and consists of soft tissue within the endometrial cavity, which may be variably enhancing. Type 3: marked endometrial vascularity more than adjacent myometriumĪrterial flow velocities >100 cm/sec can occur with low-resistance spectral waveform and large vessels present, potentially mimicking a uterine arteriovenous malformation

Type 2: moderate vascularity with nearly equal endometrial and myometrial vascularity Type 1: minimal endometrial vascularity less than the myometrium Three vascularity patterns have been established on Doppler ultrasound 12: Retained products of conception can be suspected on ultrasound if the endometrial thickness is >10 mm following dilatation and curettage or spontaneous abortion (80% sensitive) ref. Presence of vascularity within the endometrial echogenic material supports the diagnosis but the absence of color Doppler flow has a low negative predictive value because retained products of conception may be avascular 9 In some instances, this may present as an endometrial or intrauterine mass Ultrasound is typically the first-line investigation in suspected retained products of conception:Ī variable amount of echogenic or heterogeneous material within the endometrial cavity ß-human chorionic gonadotropin ( beta-hCG) remains elevated in patients with gestational trophoblastic disease but falls to an undetectable level over 2-3 weeks, in cases of retained products. Some patients may have a fever 11.ĭifferentiation of these entities is important because retained products of conception are treated conservatively or with curettage, while gestational trophoblastic disease may require chemotherapy. RPOC complicates ~2.5% (range 1-5%) of all routine vaginal deliveries 12.Īccording to one prospective study, RPOC was present after a third-trimester delivery in ~3% of women, whereas it was diagnosed in pregnancies ending during the second and first trimesters in 40% and 17% respectively 12.Ĭommon symptoms include vaginal bleeding and abdominal or pelvic pain, similar to patients with gestational trophoblastic disease.
