Larval nematodes more than 2 centimeters in length were found in eosinophilic granulomas in the stomach of two patients suffering from acute abdominal symptoms. On the basis of morphological comparison with worms identified as immature sp. from the sperm whale, the larva of one case was identified as sp., and that of the other was identified as a different but closely related species. Striking features of the larvae were large Y-shaped lateral chords extending into the body cavity, and numerous, high columnar epithelial cells forming the wall of the intestine as well as a large gland-like organ along the esophagus and upper intestine.

The infections presumably were acquired by eating raw fish, a custom that is widespread among the Japanese. It is expected that similar cases may be found among Japanese patients presenting with acute abdominal symptoms.
