Evaluation of imaging findings in gastrointestinal anisakiasis in emergency CT and ultrasound

ConclusionsThe most frequent CT findings in patients with gastric anisakiasis are wall stratification and thickening, fat stranding and ascitic fluid. In the intestinal cases, wall thickening, fat oedema and vessel engorgement are the most often observed findings.Critical relevance statementThe presence of different radiological signs makes it advisable to include anisakiasis in the differential diagnosis of acute abdomen. Intestinal and multifocal involvement rates are greater than previously reported.Key points• In gastric anisakiasis, CT frequently shows wall stratification and thickening, fat stranding and ascitic fluid.• In intestinal anisakiasis, CT often presents wall thickening, fat stranding and vessel engorgement.• In intestinal anisakiasis, ultrasounds most frequently show ascitic fluid and wall thickening.Graphical Abstract
