In our center he underwent abdominal CT scan which revealed multiple enlarged pericecal and mesenteric lymph nodes (Figure 1(a)). Repeat colonoscopy revealed multiple nodular lesions in the ascending colon and cecum (Figure 1(b)), and the biopsy revealed intramucosal Schistosoma mansoni eggs surrounded by chronic inflammatory cells, including eosinophils. To complete the investigation of intestinal chronic schistosomiasis, abdominal ultrasound revealed periportal fibrosis (Figure 1(c)) with no features of cirrhosis or ascites, and the spleen size was normal.
