From: Evaluation of imaging findings in gastrointestinal anisakiasis in emergency CT and ultrasound
Intestinal involvement due to anisakis in different locations. A and B Patient of 58 years of age with ileal anisakiasis, showing wall thickening, target appearance suggestive of submucosal oedema (white arrows), engorged mesenteric vessels (yellow arrows) and ascitic fluid (black arrows). C Patient of 68 years of age with similar findings and in addition oedema of the adjacent mesenteric fat. D Patient of 54 years of age with anisakiasis in various segments. The important involvement of the right colon (white arrows) can be noted, which showed wall and folds thickening, wall stratification, engorged mesenteric vessels and slight fat stranding. On the other hand, it also presented hyperdense circumferential wall thickening and slight engorgement of mesenteric vessels in a long segment of the ileum (black arrows)
