Adult intussusception caused by colonic anisakis: A case report

Figure 1 Pre-treatment abdominopelvic computed tomography. A and B: Axial and coronal reformatted images of contrast-enhanced computed tomography show a colo-colonic intussusception with subepithelial edema in mid transverse colon (white arrows). There is no evidence of visible tumor at intussusception in computed tomography.

Figure 2 Series of endoscopic image of descending colon demonstrating biopsy forceps removing Anisakis simplex (arrow).

Figure 3 Histopathologic images of the Anisakis body. Histopathological findings of the specimen. A: Longitudinal section of Anisakis larva. The nematode is 2.9 cm in length and 0.1 cm in width (hematoxylin and eosin stain; × 12.5); B: High magnification showing cuticle and intestine (× 200).

Figure 4 Post treatment abdominopelvic computed tomography. A and B: After removal state of parasite, repeated computed tomography images demonstrate the disappearance of colo-colonic intussusception.
