Grey scale ultrasonography in the diagnosis of ectopic pregnancy.
Grey scale pelvic ultrasonography was performed in 36 patients with suspected ectopic pregnancy and in 3 with pelvic mass and bleeding. Thirteen cases were diagnosed as extrauterine pregnancy which was confirmed at operation. There were one false-positive and 2 false-negative studies. The overall diagnostic accuracy was 92.3%. The major diagnostic criteria in unruptured ectopic pregnancy were an extrauterine gestational sac or fetus and an abnormal uterine echo pattern. In addition, a complex mass due to hematoma was seen in ruptured ectopic pregnancy. Chronic ruptured ectopic pregnancy simulated pelvic inflammatory disease and was difficult to diagnose.
