We report the ultrasonographic findings of a 60 year old woman with pseudotumorous form of ascariasis. Real-time ultrasonographic examination using a curved array transducer revealed grossly thickened small bowel loops, multiple small circular deposits throughout the peritoneal cavity, and a moderate amount of ascites. The English literature on the different forms of abdominal ascariasis is reviewed. Specific signs, which include the 'strip' sign, the 'four-lines', 'inner tube', or 'double tube' sign, the 'bull's eye' or 'target' sign, a 'worm mass' or 'spaghetti-like' appearance, and the 'zig-zag' sign can be present in any form of abdominal ascariasis, as they represent the image of the Ascaris worms visualized under ultrasonographic examination. However, the non-specific signs are not peculiar to A. lumbricoides infections, but are results of secondary changes due to A. lumbricoides infections in the corresponding organs.
我们报告了一名60岁患有蛔虫病假瘤样表现的女性的超声检查结果。使用凸阵探头进行实时超声检查发现小肠袢明显增厚，整个腹腔内有多个小圆形沉积物，并有中等量腹水。本文回顾了英文文献中关于腹部蛔虫病不同表现形式的内容。特定征象，包括“条带”征、“四线”、“内管”或“双管”征、“靶环”或“靶”征、“虫团”或“意大利面条样”外观以及“锯齿状”征，可出现在任何形式的腹部蛔虫病中，因为它们代表了超声检查下可视化的蛔虫图像。然而，非特异性征象并非蛔虫感染所特有，而是蛔虫感染在相应器官引起的继发性改变的结果。
