Gastrointestinal anisakiasis is an uncommon zoonotic parasitic infection caused by consumption of raw or undercooked seafood infected with nematodes of genus Anisakis. Given the non-specific clinical presentation of acute abdomen, nausea, and vomiting these patients are often subject to radiologic imaging. We present ultrasound and computed tomography imaging features in a case of gastric anisakiasis demonstrating characteristic features of diffuse gastric submucosal edema, perigastric stranding and trace ascites that helped to further elaborate the clinical history of uncooked fish consumption prompting timely endoscopic diagnosis and management.
