case_images: Coprological analyses using sedimentation and flotation methods revealed the presence of strongylid eggs (250 eggs/g of feces) and ultrasound revealed the presence of nodules the size of a small orange (Figure 1) located on mesenteric tissue, the colon and abdominal wall. Abdominal ultrasound scan revealed 3 large nodules of 4.2 cm x 2.1 cm on mesenteric tissue (Figure 1(b)), 4.1 cm x 2.2 cm on the descending colon (Figure 1(c)), and 3.7 cm x 2 cm on the abdominal wall (Figure 1(d)). Nodule walls were necrotic and fragile (Figure 1(d)) and the nodules on the mesenteric tissue (Figure 1(b)) and the descending colon, ruptured during the operation. The nodule on the abdominal wall was removed entirely (Figure 1(d)). Each of the 3 large nodules contained a worm but all were dead (Figure 1(c)).
