Ileal intussusception due to a parasite egg: A case report

Figure 1 Axial ultrasound image showing small bowel intussusception. The echogenic mesenteric fat is seen trapped between the intussusceptum and the intussuscipiens.

Figure 2 Corresponding coronal computed tomography (A) and sagittal computed tomography (B) images. Computed tomography images obtained after administration of intravenous contrast material show the dilated fluid-filled bowel loops (arrows) as well as the intussusceptum and the intussuscipiens in the left lower quadrant, with trapped mesenteric fat.
