Catheter dilatation in 7 cases, among them 3 cases of simple dilatation, 4 cases of dilatation catheters was not smooth and complete , saw the bulge of the little light inside the group. Solid mass in 24 cases , solid hypoechoic gland, aspect ratio <1. Hybrid mass in 2 cases, the gland was still within the realm of the Qing see mixed solid and cystic mass, cystic main groups within the floc see weak echo.
