Why multiple linear erosions in antrum radiating from pylorus?

Answer 1

Multiple linear erosions in the antrum radiating from the pylorus often indicate underlying mucosal damage, typically caused by factors like chronic gastritis, peptic ulcer disease, or the use of nonsteroidal anti-inflammatory drugs (NSAIDs). These erosions may arise due to increased gastric acid secretion or decreased mucosal protection. The pylorus, being the outlet of the stomach, is a common site for such changes due to its role in gastric emptying and exposure to acidic content. Additionally, infection with Helicobacter pylori can exacerbate mucosal injury, leading to these erosive lesions.
