Purpose: The aim of this study was to evaluate whether contrast-enhanced ultrasound (CEUS) could be used as a method for diagnosing cesarean scar pregnancy (CSP). Materials and Methods: This retrospective study reviewed medical records, CEUS results, and clinical outcomes of 30 women with CSP, admitted to the Hospital of Obstetrics and Gynecology. The women initially underwent transvaginal ultrasound followed by CEUS, using a contrast agent. The CSP lesions were classified into three types: first-trimester gestation sac type, first-trimester mass type, and second-trimester gestation sac type. Results: CEUS showed hyper-enhancement and rapid accumulation of contrast agents in the CSP lesions in the first two types and in the affected muscular layer in the third type, where the placenta accreta was confirmed histopathologically. Conclusion: CEUS can indirectly identify the intrusion of the lesion implanting into the muscular layer and give more diagnostic information before specific treatment for CSP.
