Abstract:
The clinical presentation and characteristic radiographic and angiographic findings in 6 patients with mycotic aneurysms of the pulmonary artery of aorta are presented. Radiographic findings that may suggest a mycotic aneurysm of the pulmonary artery include a rapid change in its coutour, which may be aneurysmal in character, and multiple septic pulmonary emboli or bacterial pneumonia. Patients with mycotic aneurysms of the descending thoracic aorta may have a middle or posterior mediastinal mass in close association with the aorta, and a pulmonary infiltrate may be seen surrounding the aneurysm. A barium swallow will often demonstrate esophageal displacement by the extrinsic mass.
Insights
Mycotic aneurysms of the aorta and pulmonary artery present unique radiographic signs. Early detection through imaging is crucial for diagnosing these rare infections.
Area of Science:
- Cardiology
- Radiology
- Infectious Diseases
Background:
- Mycotic aneurysms are rare but life-threatening infections involving the aorta or pulmonary artery.
- Clinical presentation can be subtle, making diagnosis challenging.
Purpose of the Study:
- To describe the clinical, radiographic, and angiographic findings in patients with mycotic aneurysms of the aorta and pulmonary artery.
- To highlight key imaging features that aid in diagnosis.
Main Methods:
- Retrospective review of 6 patients with confirmed mycotic aneurysms.
- Analysis of clinical data, chest radiography, and angiography.
Main Results:
- Pulmonary artery mycotic aneurysms showed rapid contour changes and septic pulmonary emboli.
- Descending thoracic aorta aneurysms presented as mediastinal masses with surrounding pulmonary infiltrates.
- Barium swallow revealed esophageal displacement.
Conclusions:
- Characteristic radiographic and angiographic findings can suggest mycotic aneurysms.
- Radiologists and clinicians should be aware of these specific imaging patterns for timely diagnosis and treatment.
