The roentgenographic demonstration of a gastric mucosal laceration (Mallory-Weiss Lesion).

The Mallory-Weiss lesion is responsible for many cases of upper gastrointestinal hemorrhage. Rapid diagnosis should be obtainable by endoscopic procedures. During active bleeding, angiography is the radiologic procedure of choice. The upper gastrointestinal series has been considered of little diagnostic use. Our case emphasizes that it may add valuable information when particular attention and careful technic are paid to the esophagogastric area.
