Abstract

Anisakiasis is a zoonotic parasitic infection associated with consumption of raw fish or uncooked seafood. We report a rare case of suspected esophageal anisakiasis-induced dysphagia. A 66-year-old man patient without any medical history was admitted to our hospital for evaluation of acute dysphagia. Following intake of abalone sashimi for dinner, he experienced sudden difficulty with swallowing the day before his emergency department visit. He developed skin rash and pruritus throughout his body, shortly thereafter. He also had chest and upper abdominal pain and diarrhea. He had experienced similar symptoms after consumption of raw fish on two previous occasions. Dysphagia improved 9 days later. Gastroscopy performed after symptom onset showed small erosions and edematous mucosa in the mid esophagus. Abdominopelvic computed tomography (CT) showed distal esophageal wall thickening and small bowel obstruction with concomitant ascites. We suspected anisakiasis based on the following criteria: 1) Skin rash after the third episode of consumption of raw fish or seafood (anisakiasisspecific immunoglobulin E class 4). 2) CT-documented small intestinal obstruction and ascites. 3) Eosinophil-dominant fluid observed on ascitic fluid analysis. Therefore, it is reasonable to conclude that temporary dysphagia in this patient was attributable to esophageal anisakiasis associated with raw seafood consumption.
