(a) Cyst-solid mass with size of 3.2 × 2.1 cm was found (arrow) and an annular hypoechoic halo sign surrounding the tumor was displayed (arrow head). (b) Spot calcification (arrow head) was found inside the tumor (arrow). (c) By CDFI mode, the solid component was found by multibranch threadiness color Doppler signal. (d) By PW mode, the solid component was detected by low blood flow resistance indexes (RI = 0.58).</div>
