Enteritis refers to inflammation of the small bowel. When associated with inflammation of the stomach, the term gastroenteritis is used which is usually caused by infection.
- eosinophilic enteritis
- inflammatory bowel disease
- intramural hemorrhage
- shocked bowel
- portal hypertension
- systemic lupus erythematosus: lupus enteritis
- Whipple's disease
The main feature of enteritis is small bowel wall thickening. Low density submucosal edema can usually be differentiated from higher density mural hemorrhage or infiltration. Dilatation or strictures may or may not be present, the later if chronic.
For bowel wall thickening, consider non-inflammatory causes such as:
