Ultrasonographic findings of amebic colitis.

We present here a case of a 64-year-old man with amebic colitis who was examined by ultrasonography. Gray-scale ultrasonography revealed marked thickening of the bowel wall, specifically thickening of the submucosal layer. Color Doppler ultrasonography showed hypervascularity of the submucosal and proper muscle layers. With effective treatment, thickening and hypervascularity of the bowel wall disappeared promptly. This is the first report demonstrating ultrasonographic findings of amebic colitis. We conclude that information provided by ultrasonography is useful not only for detecting the bowel abnormality of amebic colitis but also for evaluating the therapeutic effect on amebic colitis.
