Abstract：Objective To explore the causes of misdiagnosis of cesarean scar pregnancy (CSP) by ultrasound (US) and preventive methods to avoid misdiagnosis. Methods Ultrasound sonograms and clinical data of 17 cases of CSP misdiagnosed by ultrasound from January 2010 to July 2018 were retrospectively analyzed. Results In this group, 15 cases had endogenous CSP and 2 cases had mass-type CSP.For those with endogenous CSP, 11 was misdiagnosed as having intrauterine early pregnancy, and 4 as inevitable abortion.Mass-type CSP was misdiagnosed as uterine fibroids in 1 case and gestational trophoblastic tumor in 1. All of the 17 patients had a history of menopause, and the duration of misdiagnosis was 5 d to 10 weeks. After completion of the ultrasound examination, all patients were diagnosed as CSP, and hysteroscopic or laparoscopic removal of scar pregnancy lesions was performed. Seventeen patients recovered after surgery, and scar pregnancy lesion disappeared by ultrasound examination. Conclusion Insufficient understanding of CSP, non-standard ultrasound examination, narrow diagnosis thinking and improper timing of the ultrasound examination are the causes of misdiagnosis.
