The purpose of this exhibit is: 1. To illustrate CT findings of intestinal anisakiasis in patients attended in the emergency setting. 2. To emphasize those CT findings which allow the radiologist to suggest the diagnosis of intestinal anisakiasis,  despite an alternative clinical suspicion.

Retrospective review of the emergency department clinical records of a tertiary hospital, finding 21 patients diagnosed with intestinal anisakiasis, who underwent CT examination, from January 2011 to December 2013. Diagnosis was made in patients with prior raw fish ingestion, based on positive results for Prick-test, total IgE and Anisakis-specific IgE levels and the presence of intestinal lesions on CT. CONTENTS: Patient demographic information and time of onset of symptoms Clinical presentation and initial diagnosis before CT examination: table 1 CT findings in intestinal anisakiasis: table 2 and figures 1-3 -Ascites, small bowel wall thickening, submucosal edema and luminal narrowing, proximal small bowel dilatation (14 patients [66,7 %] ) and occasional dilatation of distal bowel with fluid content, affected bowel segment length greater than 10 cm (14 patients [66,7 %] ) and mesenteric fat infiltration.          4. CONCLUSION: Radiologist could suggest intestinal anisakiasis based on MDCT findings.
