Diagnosis With Brief Discussion
- Diagnosis
- Acute Phlegmonous Esophagagogastritis
- Radiologic Findings
- Initial CT images show diffuse wall thickening and intramural low-density area in whole esophagus and upper stomach. Intramural low-density area is surrounded by peripheral enhancing rim, that is suggestive of intramural abscess.
After 1 week, air bubbles are newly appeared in thickened esophageal wall, which means the intramural abscess spontaneously drained into the esophageal lumen.
- Brief Review
- Acute phlegmonous esophagitis is uncommon disorder. A bacterial infection occurs in the submucosa and musculature of the esophagus. Phlegmonous infection usually involves the submucosa and not the mucosa. Phlegmonous gastritis is more common than phlegmonous esophagitis and may be either localized or diffuse.
The pathogenesis of acute phlegmonous esophagitis is unclear. Reported predisposing factors include immune suppression, alcoholism, peptic ulcer disease, chronic gastritis or some other gastric mucosal injury, achlorhydria, infection, connective tissue disease, and malignancy. Presumably, these conditions predispose the stomach to infection by eliminating various defense mechanisms, such as, inherent gastric cytoprotection or the bactericidal effect of gastric acid. Nevertheless, approximately 50% of reported cases were previously healthy and had no significant anteceding risk factors.
CT findings of phegmonous esophagitis are esophageal wall thickening and intramural low-density areas. The area of intramural low attenuation surrounded by a peripherally enhancing rim represents intramural abscess. The air bubbles in the thickened esophageal wall seen on CT may be produced by gas-forming organisms (indicating emphysematous esophagogastritis), or the air bubbles may have entered the wall when the intramural abscess spontaneously drained into the lumen.
