[Extension of infiltrating cancer of the stomach into the transverse colon (author's transl)].

The extension of infiltrating stomach cancer through the gastrocolic ligament into the transverse colon appears to be relatively common. The radiological appearance is characteristic, with more or less widespread, but shallow, extrinsic prints with irregular contours typical of malignant tumours. Its gastric origin is strongly suggested by its position of the superior border of the transverse colon. The authors report 6 observations in which the value of this very characteristic radiological abnormality of the colon to diagnose primary stomach cancer was confirmed. Radiological appearances are not very specific in primary stomach cancer and interpretation is often difficult; endoscopy or even biopsies are often inconclusive.
