[Aphthous ulcers--an early radiological sign of Crohn's disease? (author's transl)]
Abstract:
Thirty-eight patients with histologically confirmed Crohn's disease are described. Eleven of these showed so-called aphthous ulcers. These were most common in the colon (five patients) and terminal ileum (four patients). Aphthous ulcers are small mucous membrane erosions on the surface of hypertrophic lymph follicles with surrounding oedema. From our material and from the literature we conclude that aphthous ulcers are occasional radiological signs and not invariable early signs of Crohn's disease. Their specificity has not been proved. Differentiation from gastric erosions in cases of gastro-duodenal involvement is discussed.

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.
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
