“…Denega et al reported that carcinoma of the azygos lobe is not associated with regional lymph node involvement [ 8 ]. This was confirmed by Darlong et al who reported a squamous cell carcinoma arising in the azygos lobe with negative mediastinal lymph nodes [ 6 ]. Fukuhara et al described a case of a solitary nodule in an azygos lobe of the right lung, 2 cm in diameter, verified as an adenocarcinoma, again without any metastatic involvement of the regional lymph nodes and treated successfully with robot-assisted thoracic surgery [ 4 ].…”

“…This anomalous structure did not present with any clinical symptoms. On imaging studies, the azygos lobe may mimic an enlarged thymus, a substernal goiter, a localised pneumothorax, bulla, lung abscess, or neoplasm [ 2 , 6 - 7 ]. Diagnosing the azygos lobe may be further complicated by physiological changes in the size of the azygos vein or morphological variants of the fissure [ 8 ].…”

“…Clinically, the azygos lobe is a variation that can simulate various diseases and is most often found incidentally during chest radiography or computed tomography (CT) [ 5 - 6 ]. Its radiographic appearance is that of a dense, comma-shaped shadow which begins at the apex of the right lung and curves downwards and inwards towards the mediastinum, ending a little below the level of the first costal cartilage [ 1 ].…”

The azygos lobe is a rare anatomical variant, most often encountered in the right lung. Its etiology is related to a defect of the migration of the azygos vein during the embryonic development. Here, we describe a rare case of an azygos lobe of the right lung, diagnosed incidentally on a computed tomography (CT) scan in a 40-year-old male patient who presented with chest pain, shortness of breath, and fever. The initial differential diagnosis included acute myocardial infarction, aortic dissection, and myocarditis. Chest CT with contrast matter demonstrated a peculiar finding in the right lung which was recognized as an azygos vein passing through the upper lobe and separating an azygos lobe with its mesoazygos. The azygos lobe may be rarely associated with neoplastic processes or spontaneous pneumothorax and its differential diagnosis on imaging studies includes various conditions. Knowledge of this variation is important to avoid misdiagnosis or complications during thoracic surgery.

“…In the literature, there are described cases of an azygos lobe lung cancer-a small cell carcinoma and a non small cell carcinoma, and their surgical treatment [3,17]. It is worth noting, that in the previous studies, authors reported that the azygos lobe carcinoma is not associated with regional lymph node involvement [7], which has been repeatedly confirmed [5,18]. Although lung cancers occur in the azygos lobe, they are not very common.…”

Clinical characteristics of 50 children with azygos lobe: a retrospective study

et al. 2021

View full text Add to dashboard Cite

BackgroundAn azygos lobe is a rare anatomic variant of the lung which may be misdiagnosed as other pathological conditions. This study aimed to summarize the clinical characteristics and imaging manifestations of azygos lobe in children, which will be helpful for reasonable management and counseling of their families. Children with imaging ndings of azygos lobe from West China Second University Hospital of Sichuan University (Chengdu, China) between November 2008 and February 2019 were enrolled in the study. Clinical and radiologic characteristics of these patients were collected and analyzed. ResultsIn total, 50 patients were included. 28% children were diagnosed as azygos lobe incidentally. The other 72% cases were diagnosed when they manifested respiratory symptoms including cough (18/50, 36%), fever (17/50, 34%), wheezing (9/50, 18%), dyspnea (7/50, 14%), and cyanosis (4/50, 8%). Congenital heart disease, Down syndrome, and other respiratory malformations were also found in a small proportion of these patients. In our study, all cases with azygos lobe had the right lung involved. Other imaging manifestations of these cases consisted of increased marking and in ltrates in the lung elds, local emphysema, consolidation, and atelectasis et al. Among the patients, only 8 patients (16%) diagnosed as azygos lobe infection. Compared with the non-infected group,there were no valuable risk factors related to the azygos lobe infection. And all the children with azygos lobe infection were cured after reasonable anti-infective treatment. ConclusionChildren with azygos lobe were diagnosed mostly because of respiratory symptoms and these children had a good prognosis after resonable treatment. Only a small number of patients suffered from azygos lobe infection. Some of the patients with azygos lobe were found to have other organ malformations as well, which needed further monitoring and study.

The Azygous Lobe of the Lung: in the Case of Lung Cancer

Abstract: The azygous lobe of the lung is an uncommon developmental anomaly. Its surgical importance is hardly being described in literature. Here, we are presenting a case of lung cancer with incidental azygous lobe, with its surgical relevance during lung cancer surgery.
