“…Some authors consider that aneurysms larger than 5 cm determine the apparition of symptoms, due to the compression of adjacent structures, such as oesophagus, bronchi, SVC, and pneumogastric nerve (28). Most frequent symptoms found are: i) dysphagia, ii) persistent cough, iii) heart palpitation and iv) chest thickness (12).…”

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.

“…There has also been a report of presyncopal symptoms as the only clinical manifestation in a patient with orthostatic hypotension (29). Other symptoms, such as wheezing, cough and persistent hiccups have been also described (28), While AVA is also considered to be caused by the irritation or compression of the vagus nerve (28).…”

“…Marked enlargement of a portion of the azygos vein has been referred to as a varix ( 3 , 4 ) or an aneurysm ( 5 , 6 , 7 , 8 , 9 , 10 ). Some authors suggest that a venous varix and a venous aneurysm have different vessel wall histology ( 5 ), with varices having increased fibrous tissue and medial thickening and aneurysms showing reduced number and size of muscle and elastic fibers, intimal hyalinization, fragmentation of the internal elastic lamella, and excessive fibrous connective tissue.…”

“…Video assisted thoracoscopic resection is an attractive method of surgery in selected cases with no thrombus, 10) and thrombolytic therapy, stent-graft replacement, and transcatheter occlusion have also been tried and proved effective in limited cases. 11) 12) 13) Further studies are necessary for comparison of new modalities to surgical intervention in specific situations.…”
