Abstract
We examined two patients with gastric anisakiasis by ultrasonography. The patients were a 36-year-old woman and a 29-year-old women. Both showed typical findings on ultrasonography, markedly and diffusely thickened walls from the pylorus to the gastric corpus, very smooth surfaces and low homogeneous internal echoes. In one patient opening of the internal space of the thickened wall was revealed by drinking water and changing position. This suggests that thickened walls have extensibility, and that therefore, differential diagnosis from malignant disease may be possible.
In each patient the gastrofiberscope revealed an elevated lesion with a small worm hanging in its center. This worm was removed by the endoscope and was found to be an anisakis. The symptoms were diminished at once. One patient showed a normal thin wall of the stomach one month after onset of the symptoms.
Ultrasonography is useful to diagnosis gastric anisakiasis or inflammatory disease of the stomach which shows a thickened wall.
