A few days later there was a mass in the wound, touching the vessel-like pulse. Now our hospital diagnosis and treatment, with ultra “9” type 5MHz line array probe, set the mass at the detection of a 7 × 4.2cm size cystic mass, wall thickness 0.3-0.5cm. The inner wall of the neat, lumps of the wall with the heart rhythms consistent with the synchronized beats, the blood flow was swirling echo.
