Diagnosis of abdominal wall scar endometriosis by color duplex ultrasonography

Objective To describe the features on two-dimensional and color Doppler ultrasonography of abdominal wall scar endometriosis.Methods Ultrasonographic appearances of endometriosis in abdominal wall scar confirmed by pathology in 7 patients were retrospective analyzed.Results Their ultrasonographic features were mass-like structure with ill-defined and irregular contour,heterogeneous and hypoechoic internal echoes in the abdominal wall scar. There were masses with peripheral hypervascularity on color Doppler flow imaging. Spectral Doppler revealed low speed (PSV 6.5-19 cm/s) and high resistance (RI 0.71-0.85).Conclusion Ultrasonography is helpful to the diagnosis and differential diagnosis of abdominal wall scar endometriosis.
