为了对儿童期曼氏血吸虫感染引起的声像图异常进行分期，对536例6-15岁的患者进行了广泛的声像图检查。门静脉周围纤维化的特异性结果分为3级，发生在研究患者中，但未发生在对照组中（n = 60）。I级包括回声带，通常直径> 4 mm，在门静脉分叉和胆囊颈区域最明显。常可见连续的U形回声结构从门静脉左分支延伸至胆囊床。Ⅱ级：门静脉中央及主要分支周围可见直径> 10 mm的回声带;除了与II级相同的特征外，III级还包括不局限于门静脉腔但延伸到肝脏外周的条纹状纤维带。儿童S.曼氏菌感染与成人有显著差异。
For the purpose of staging sonographical abnormalities induced by Schistosoma mansoni infection in childhood, 536 patients aged 6-15 years underwent extensive sonographical examination. Specific findings of periportal fibrosis were classified in 3 grades and occurred in study patients but not in controls (n = 60). Grade I consisted of echogenic bands usually with a diameter > 4 mm that were best visible in the area of the portal vein bifurcation and gallbladder neck. Frequently a continuous U-shaped echogenic structure extended from the left portal branch to the gallbladder bed. Grade II, was characterized by echogenic bands usually > 10 mm in diameter around the central part and major branches of the portal vein. In addition to features common to grade II, grade III included streak-like fibrous bands that were not confined to portal vein lumina but extended into the periphery of the liver. Sonographical abnormalities encountered in children with S. mansoni infection differed significantly from those in adults.
