Abstract:
Although the overall prevalence of peptic ulcer disease (PUD) has decreased in modern times, its actual incidence may be underestimated owing to the nonspecific clinical presentations patients' manifest. The potential lethal complications that can result from PUD include life-threatening abdominal hemorrhage and bowel perforation that result in significant morbidity and mortality. Computed tomography (CT) imaging historically lacks specificity in detecting PUD-related pathology in the stomach and proximal small bowel segments. Therefore, these are potential pitfalls in the radiologist's search pattern on abdominopelvic CT imaging. This article highlights imaging features of uncomplicated PUD on CT imaging in order to allow for early detection of this disease process on imaging and the prevention of potential high-grade complications by recommending esophagogastroduodenoscopy.

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
