title: Arterial impressions on the stomach.
abstract: The splenic artery frequently produces a contour defect on the posteromedial aspect of the stomach, particularly in elderly individuals. When the artery is tortuous or aneurysmal, the impression is prominent and may simulate a neoplasm. Similarly, the aorta can produce a gastric impression. Recognition of these impressions on the stomach wall avoids erroneous diagnosis and unnecessary exploratory surgery.
