Abdominal wall endometriomas near cesarean delivery scars diagnosed by color Doppler ultrasound

Objective To describe the sonographic and color Doppler features of abdominal wall endo-metriomas near cesarean delivery scars.Methods Ultrasonographic appearances of abdominal wall endometriomas of 8 patients confirmed by pathology and operation were analyzed retrospectively. Results Sonography disclosed that all nodules were located at subcutaneous tissue.The nodules size was 1.6-3.7cm. The sonographic features were irregular shape and irregular margins, often speculated, infiltrating the muscularis fascia; a hypoechoic in homogeneous echo texture with internal anechoic lacunae.Color Doppler examination showed that the color signal pattern was dot-like and/or linear with low-velocity and high-resistance arterial flow in all the patients.Conclusion Color Doppler ultrasound,when properly combined with clinical data,may be a valuable method for diagnosing abdominal wall endometriomas.
