摘要： 超声是一种简便、无创、直观的检查方法，易被患者接受，且诊断符合率较高，可直接观察到病变周围的形态大小、有无粪石，对有无穿孔也有帮助。急性单纯性阑尾炎阑尾稍增粗，粘膜和粘膜肌层轻度增厚，化脓性和坏疽性阑尾炎阑尾明显增粗，腔内可见脓液回声，稀薄者为无回声暗区，粘稠者为密集点状强回声；化脓性阑尾炎声像图显示欠清晰，外形不规则，粗细欠均匀，周边伴有少量液性暗区；坏疽性阑尾炎声像图特征形态消失，壁模糊，回声中断，周围可见不规则的低无回声区，内部回声不均匀，后方回声增强。

    Abstract ultrasonography is a simple, noninvasive, visual inspection method, easily accepted by patients, and the diagnosis coincidence rate is higher, can be directly observed the pathological changes around the shape size, the presence of bezoar, the presence of perforation can also help. Slightly enlargement, acute simple appendicitis appendix mucosa and mucosal muscularis mild thickening, suppurative and appendix gangrenous appendicitis enlargement, obviously with pus cavity, anechoic dark area is thin, thick for dense point strong echo. The sonograms of acute suppurative appendicitis showed less clear, shape is irregular, uniform thickness to owe, accompanied by a small amount of fluid surrounding the dark space. Gangrenous appendicitis ultrasonographic characteristics of the form will disappear, wall, echo, visible around irregular low anechoic area, uneven internal echo, posterior acoustic enhancement. ...... 婵″倹鐏夐幃銊ユ躬娴ｈ法鏁ら幍瀣簚缁涘绁︾憴鍫熸閺冪姵纭堕弻銉ф箙閹存牔绗呮潪钘夊弿閺傚浄绱濋崣顖濆厴閺勵垵顫﹂幖婊呭偍瀵洘鎼告径杈╂埂閳ユ粏娴嗛惍浣测偓婵撶礉鐠囬鍋ｉ崙璇茬潌楠炴洘娓舵稉瀣煙閻ㄥ嫧鈧粎鏁搁懘鎴犲閳ユ繃鍨ㄩ垾婊冨斧缂冩垿銆夐垾婵婎問闂傤喓鈧拷
