Highlights
- •Gastric anisakiasis, a rare zoonotic disease in western hemisphere, may present with non-specific symptoms of acute abdomen
- •Imaging findings of diffuse gastric submucosal edema, perigastric fat stranding and ascites are described on ultrasound and CT
- •Attention to stomach for any concerning findings on ultrasound, commonly performed for RUQ pain, may be useful to raise the diagnostic possibility
- •Confirmation and treatment requires upper gastrointestinal endoscopy
Abstract
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.
