Abstract
We present a case of unsuspected gastric carcinoma discovered as a result of abnormalities seen on a sulfur colloid gastric-emptying study. Considered a functional or physiological analysis, often relatively little attention is given to the morphology of the stomach except for the purpose of drawing a region of interest. This case, in which the images suggested a space-occupying lesion(s), emphasizes the importance of careful examination for “pathoanatomy” as well as pathophysiology in functional imaging.
