Diagnosis With Brief Discussion
- Diagnosis
- Acute phlegmonous esophagitis
- Radiologic Findings
- Fig 1. Chest PA shows increased opacity in BLLZ and abnormal bulging of the descending thoracic aorta.
Figs 2-3. Mediastinal window setting of the chest CT scan shows diffuse edematous circumferential wall thickening of the esophagus along with intramural low density lesion. On coronal image, the lesion extends to the gastric cardia.
- Brief Review
- Acute phlegmonous esophagitis is purulent inflammation of the submucosa and muscular layer of the esophagus, sparing the mucosa. It is a potentially fatal disease with many complications, such as esophageal perforation, mediastinitis, peritonitis, and empyema.
There are many predisposing factors, such as immune suppression, alcoholism, peptic ulcer disease, chronic gastritis or some other gastric mucosal injury, achlorhydria, infection, connective tissue disease, and malignancy.
CT findings of acute phlegmonous esophagitis are diffuse esophageal wall thickening and intramural circumferential low attenuated area of the esophagus, surrounded by peripheral rim enhancement. It is suggestive of abscess in the submucosa and muscularis layer of the esophagus. Some cases present with air bubbles within the thickened wall, due to gas-forming pathogens.
