“…Some authors do not recommend surgery for asymptomatic AVA due to the risk of pulmonary embolism during the intraoperative manipulation of the lesion (4,9,38). Other authors agree that treatment of AVA should be conservative, and surgery should be reserved for complicated cases or when a clear diagnosis is not possible (18,40). In our case, surgery was performed with the suspicion of a mediastinal tumoral mass, while the diagnosis of AVA was made intraoperatively and confirmed later on by the histopathological studies.…”

Background/Aim: Azygos vein aneurysm (AVA) is a rare thoracic pathological entity that mimics a posterior mediastinal mass as well as a right paratracheal mass. Usually asymptomatic, AVA is often accidentally discovered during routine chest x-rays; however, depending on the aneurysm size and complications, some symptoms may be present. The aim of this paper is to report a case of idiopathic AVA and to discuss its aetiology, embryonic origin, symptoms, complications, diagnostic methods and treatments. Case Report: A 74-yearold female was investigated for diffuse thoracic pain and submitted to standard chest x-ray, which identified a right paratracheal, well-defined, homogenous opacity, considered to be part of the mediastinal shadow. The patient was further submitted to thoracic computed tomography, which confirmed the presence of a tumoral mass at the level of the right paratracheal area. The patient was submitted to surgery and the tumoral mass was resected; however, the tumor proved to be a completely thrombosed aneurism of the azygos vein arch. Conclusion: AVA is a rare pathology that must be taken into consideration during the differential diagnosis of right posterosuperior mediastinal masses.

Azygos lobe represents normal variation of the pulmonary anatomy. Aneurysmal of azygous vein is very rare and patient remains asymptomatic. Here we report two cases of azygos lobe; one with normal azygous vein diameter and another case with aneurysmal azygous vein. Both cases were incidental detected during Computed Tomography scan. Fusiform aneurysm of azygos vein within azygos fissure has never been reported.

“…Too much pressure or volume caused by, for example, heart failure may result in the azygos vein dilatation and aneurysm formation. Idiopathy may include congenital malformation . This case was regarded as an idiopathic aneurysm because the patient did not have any past history of chest trauma or congenital heart failure.…”

Azygos vein aneurysm is a rare disease. Surgical resection is usually performed when it ruptures. To avoid the thromboembolism, procedures that do not touch or push the aneurysm are recommended. Herein, we report a case of idiopathic azygos vein aneurysm. A 56-year-old woman was admitted to the hospital for right lateral chest pain. Chest enhanced multi-detector CT revealed an azygos vein aneurysm in the posterior mediastinal space. No thrombus in the aneurysm was detected before surgery. Video-assisted thoracic surgery was performed to treat the aneurysm. The patient was discharged from the hospital 4 days after surgery. Video-assisted thoracic surgery was a good option to treat an azygos vein aneurysm, and an enhanced multi-detector CT was useful for performing surgery safely.
