We assessed 5 patients with histologically/clinically confirmed placenta accreta after first‐trimester abortion. In 4 patients, sonography showed an unclear endometrium, absence of an endometrium‐myometrium interface, a well‐vascularized hyperechoic lesion in the uterine body with a low resistive index, and myometrial thinning near the lesion. In 2 patients, contrast‐enhanced sonography showed rapid irregular lesion enhancement. Chemotherapy reduced the lesions in 3 patients, and a decreased blood supply increased the resistive index in all lesions. Two patients each underwent hysterectomy and uterine curettage. The fifth patient had a cervical pregnancy; sonography showed a well‐vascularized hyperechoic lesion in an enlarged cervix. Methotrexate gradually reduced this lesion. Sonography, especially contrast‐enhanced sonography, can detect placenta accreta and guide treatment.
