Value of high frequency ultrasonography in the diagnosis of abdominal wall endometriosis

Objective To evaluate the value of high frequency ultrasonography in the diagnosis of abdominal wall endometriosis. Methods Ultrasonographic features of 26 cases with abdominal wall endometriosis confirmed pathologically were analysed retrospectively. Results Among 26 cases of endometriosis,the masses of 19 cases located in adipose layer and 7 cases in muscular layer.All masses located in the abdominal wall under surgical incision close to soft tissue.They were 1.2~5.1cm in diameter with blur margin and irregular shape,and hypoechoic inhomogeneous texture with small part of echoless area on sonography.Color Doppler exemination showed spottly or linear color signals with low-velocity and high-resistance arterial waveform.Conclusion High frequency ultrasonography shows the size,morphosis, echoegenicity and blood supply of abdominal wall endometriosis directly,which plays an important role in the diagnosis of abdominal wall endometriosis.High frequency ultrasonography can be the first line imaging modilaty in the diagnosis of abdominal wall endometriosis.
