Ultrasonographic types of ectopic pregnancy: (a) Fetal sac type: early rupture of the fallopian tube without rupture, ultrasound reveals an intact fetal sac in the adnexal region, and sometimes fetal buds and fetal heartbeats can be seen. (b) Attenuated mass type: After tubal rupture or miscarriage, the fetal sac and blood flow out and coalesce around the fallopian tube and umbilical end, forming a hematoma; the chorionic villi continue to erode causing repeated bleeding out to the rectal fossa, iliac fossa and abdominal cavity, which is manifested if most of the blood does not coagulate into a mass. (iii) Mixed mass type: The fallopian tube has ruptured for a long time, forming a large blood clot, which mixes and fuses with the outflowing fetal sac and becomes a complex mass. The mass has a strong echogenic mass (this is a clot) and a fluid area (uncoagulated blood or serum), and the mass may also contain tissue that resembles the structure of the fetal sac, forming a mixed mass. (4) Solid mass type: this type of pregnancy is mostly old ectopic pregnancy; that is, after the formation of the hematoma, it continues to bleed by the erosion of the villi, and the hematoma continues to increase in size, and as time passes, the hematoma becomes mechanized, the fluid is absorbed, and a connective tissue pseudo-envelope is formed outside the hematoma. Thus, old ectopic pregnancy may show an image of a “large uterus”, which is actually a tight adhesion between the hematoma and the uterus, and the mass may be misdiagnosed as a solid ovarian tumor because it is solid. (E) floating type: after rupture of tubal pregnancy, if there is acute massive bleeding, the condition is fierce and critical at the time of consultation, such patients are mostly seen with ruptured interstitial pregnancy, ruptured residual horned uterus pregnancy, etc., which can cause acute massive internal bleeding within a short period of time, the uterus feels floating on gynecological examination, the sonogram shows the uterus floating in a large amount of blood, and a large amount of blood can be seen in the abdominal cavity. In addition to abdominal pain, the patient has pale facial skin and anal swelling.
