Summary
We report an extremely rare case of an asymptomatic azygos vein aneurysm. Dynamic CT imaging was crucial for preoperative diagnosis of this vascular abnormality, highlighting the need for careful consideration of resection for smaller, asymptomatic masses.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Thoracic Medicine
Background:
- Azygos vein aneurysms are exceptionally rare congenital or acquired vascular malformations.
- Asymptomatic presentations of vascular abnormalities in the thoracic region pose diagnostic challenges.
Observation:
- A case of an asymptomatic saccular aneurysm of the azygos vein is presented.
- Dynamic computed tomography (CT) demonstrated intense enhancement of the mass, indicative of a vascular origin.
Findings:
- The dynamic CT findings were critical for accurate preoperative diagnosis.
- The vascular nature of the azygos vein mass was clearly identified.
Implications:
- The findings underscore the importance of advanced imaging in diagnosing rare vascular anomalies.
- Management decisions regarding resection of asymptomatic, incidentally discovered azygos vein aneurysms require further investigation.
