Abstract
Patient aged 71 with a history of type 2 diabetes mellitus. He came to the emergency department for abdominal pain and vomiting. Laboratory tests showed an increase in acute phase reactants. Abdominal CT scan showed dilated jejunal loops, compatible with intestinal occlusion. Urgent intervention was performed, resecting the affected segment. The pathology report showed a prominent transmural inflammatory infiltrate and interstitial oedema, with moderate villous atrophy, identifying parasitic structures compatible with anisakis larvae (family Anisakidae). Given the mechanism of tissue invasion, the larvae are surrounded by a predominantly eosinophilic inflammatory infiltrate, organised as granulomas or abscesses.
