本文报告５例回盲部血吸虫肉芽肿，其中１例癌变。其影像学表现：（１）大小不等，边缘光滑，凸入腔内较深的息肉样充盈缺损．（２）息肉样充盈缺损的颗粒之间被挤压聚集的条索状粘膜纹。（３）回肠末端受累时粘膜粗乱或／和息肉样充盈缺损，无粘膜破坏是与癌肿鉴别的重要征象。充盈缺损周围粘膜增粗在鉴别诊断中也有参考。钡剂灌肠结合ＣＴ扫描可提高诊断正确率。
This article reports 5 cases of ileocecal schistosomal granuloma, of which 1 case of cancer. The imaging findings: (1) ranging in size, smooth edges, protruding into the cavity of the deep polypoid filling defect. (2) Polyps-like filling defects between the compressed particles gathered cord-like mucosa. (3) mucosal thick disorder or / and polypoid filling defects when the terminal ileum is involved, and no mucosal damage is an important sign to identify with the cancer. Filling defects around the mucosal thickening in the differential diagnosis is also a reference. Barium enema combined with CT scan can improve the diagnostic accuracy.
