The ultrasonography permits the study of the natural history of cystic echinococcosis (CE) and evaluation of stages of the parasitic pathology. The evolution of abdominal CE was studied in 54 patients suffering from 97 abdominal cysts treated with albendazole, in 20 patients suffering from 20 hepatic cysts treated with echoguided percutaneous ethanol injection and in 39 patients suffering from 42 abdominal cysts, but left untreated. A new sonographic classification is suggested. Type I: Simple CE; (a) overall echofree; (b) with fine echos. Type II: Multiple CE; (a) multiple contiguous; (b) multiseptated with rosette, honeycomb and wheel-like pattern. Type III: With detachment of endocyst CE; (a) with double layer image; (b) with water-lily sign. Type IV: Mixed type CE; with fluid and solid aspect. Type V: Heterogeneous CE; (a) with ball of wool pattern; (b) with hypoechogenic image. Type VI: Hyperechoic CE; (a) with snow-storm pattern; (b) with dyshomogeneous aspect. Type VII: Calcified CE; (a) with advanced calcification of the layer only; (b) with calcification of overall cyst. This classification appears more appropriate to the natural history of CE and permits a better differential diagnosis and more suitable treatment.
超声检查可用于研究囊性棘球蚴病（CE）的自然病程，并评估寄生虫病理学的各个阶段。对54例患有97个腹部囊肿且接受阿苯达唑治疗的患者、20例患有20个肝囊肿且接受超声引导下经皮乙醇注射治疗的患者以及39例患有42个腹部囊肿但未接受治疗的患者的腹部CE演变情况进行了研究。提出了一种新的超声分类方法。I型：单纯性CE；（a）整体无回声；（b）有细回声。II型：多发性CE；（a）多个相邻；（b）有分隔，呈玫瑰花结、蜂窝状和轮状图案。III型：内囊CE分离型；（a）有双层图像；（b）有睡莲征。IV型：混合型CE；有液性和实性表现。V型：不均匀型CE；（a）有毛球样图案；（b）有低回声图像。VI型：高回声型CE；（a）有暴风雪样图案；（b）表现不均匀。VII型：钙化型CE；（a）仅外层有晚期钙化；（b）整个囊肿钙化。这种分类似乎更适合CE的自然病程，有助于更好地进行鉴别诊断和采取更合适的治疗方法。
