Diagnosis With Brief Discussion
- Diagnosis
- Intramural hematoma of esophagus (developed after anticoagulation therapy)
- Radiologic Findings
- On initial CT images, there are no abnormal findings in the esophagus and surrounding posterior mediastinum. An aneurysm is noted in the left subclavian artery. Follow-up CT images obtained 2 days later show a tubular mass of homogeneous density with a sharp and smooth outer margin in the retrotracheal area that compresses the trachea. The esophageal lumen is not clearly identified at those levels, but the mass extends along the esophageal course up to the aortic arch level. CT scan at the left atrial level shows a normal esophagus, pleural fluid and focal atelectasis in the dependent lungs. A metallic stent is noted within the left subclavian artery.
This patient had been suffered from an aneurysm in the left subclavian artery and thrombotic arterial obstruction in the forearm. Thrombolysis was performed by intraarterial instillation of Urokinase and intravascular stent was introduced to the subclavian artery. He was treated with heparinization for 2 days.
- Brief Review
- Spontaneous intramural hematoma of the esophagus is probably due to spontaneous bleeding within the submucosal layer of the esophagus, usually associated with a rapid increase in intraesophageal pressure, particularly in the presence of coagulophathy. The clinical presentation is often acute retrosternal or epigastric pain accompanied by dysphagia, odynophagia, or hematemesis. The condition may mimic Mallory-Weiss syndrome, Boerhaave syndrome, acute myocardial infarction, or dissection of the thoracic aorta. Esophagogram may show narrowing of the esophageal lumen by a long, submucosal intramural mass. In cases with intramural dissection, mucosal tear or a “double-barreled esophagus” or “mucosal stripe” sign may be demonstrated. CT and MRI are useful for demonstrating esophageal mass and differentiating from other mediastinal disorders.
