“…It has no serious consequences by itself, and there is no need for special treatment; however, accompanying conditions may warrant attention. Bronchial carcinoma, pneumothorax, bullous changes, and vascular abnormalities have been reported to accompany AL [1, 5–7]. Various approaches have been successfully employed for those pathological conditions.…”

Although it is not a pathologically significant entity, cases of azygos lobe (AL) are interesting due to the difficulty of performing video-assisted thoracoscopic surgery (VATS) procedures in the affected patients and the presence of a congenital malformation. Currently, videothoracoscopic surgery has advanced to such a level that most thoracic procedures can be performed with video assistance. However, some technical difficulties may arise in cases with anatomical anomalies such as AL. This report presents the case of a patient with an azygos lobe who underwent videothoracoscopic lung resection due to the presence of non-small-cell lung carcinoma in the upper lobe of the right lung.

“…The number of studies on the subject is limited; however, it is worth noting the report by Fukuhara et al [5], in which a patient with non-small-cell lung cancer originating from the azygos lobe was operated on using a robot-assisted technique.…”

“…The rst report of a right upperlobectomy by video-assisted thoracic surgery (VATS) in a patientwith an azygos lobe was published by Arai et al [10]. Some tumors may originatedirectly from the azygos lobe reported in several research [9,19,20]. In Fukuharaet al [20]research, they rstly reported the case with operativedemonstration of a primary adenocarcinoma arising from an azygoslobe, which was treated with robot-assisted azygos lobectomy.…”

Background Primary disease in thorax associated with an azygos lobe is extremely rare. It is usually identified incidentally on chest X-ray or CT during health checkups with an incidence of up to 0.2%. This is the first study involving 46 of patients found with azygos lobe in surgery of English literature from January 1931 to October 2018. Methods PubMed, EMBASE and the Web of Science databases were searched for full-text literatures met out inclusion criteria. We summarized the clinical data, radiological manifestation, accompanying disease and treatment strategy of all patients. Results 18 eligible studies involving 46 patients were selected for this research. The mean age was 36.5 years old. There were 26 male patients and 20 female patients and the male to female ratio nearly to 1.3:1. There were many different primary diseases with azygos lobe including lung cancer (n = 8), spontaneous pneumothorax (n = 5), esophageal cancer (n = 1), pulmonary sequestration (n = 1), esophageal atresia (n = 2), hyperhidrosis (n = 29). The azygos lobe (azygos lobe in Figs. 1 and 2) is an uncommon anomaly that is found in 1% of anatomic specimens, on about 0.4% of chest radiographs and 1.2% of high resolution CT. The azygos lobe is a developmental anomaly but not a true accessory lobe. Azygos lobe of all patients was diagnosed during the operation. Conclusions Azygos lobe occurs in 0.2% of the population and can make clinical diagnosis difficult. The detection of this anomaly and clarification of its precise anatomical features are important to alert the surgeon to potential problems during surgery.

“…Azygos lobe related tumors are defined in the literatures. Superior sulcus tumor arising in an azygos lobe [14], azygos lobe small cell carcinoma [15], and adenocarcinoma arising in an azygos lobe [16]. Superior sulcus tumors usually arise in the apex of the lung and may invade the brachial plexus, the subclavian vessels, the second and third ribs, the stellate ganglion and adjacent vertebral bodies [14].…”

“…However, neither the surgical/oncological implication of having a tumour confined to an azygos lobe, nor the reasons for rarity of cancer development in this lobe is known, despite its being a common anatomical variance. One theory hypothesizes that this rarity of cancer development results from decreased ventilation of the azygos lobe [16], While this is a controversial assumption, the ventilation of an azygos lobe may be relatively limited due to constriction by the azygos vein, possibly resulting in less oxygen delivery and particle deposition of carcinogens thereby restricting carcinogenesis within this lobe despite its apparent segmental or subsegmental bronchovascular supply [16].…”

ÖzetAzigos lobunu bilmek göğüs cerrahisi prosedürleri sırasında önemlidir. Azigos lob azigos venin sebep olduğu nadir bir bronkopulmoner segmentasyondur. Tek başına hiçbir patolojik anlam ifade etmez iken, farklı patolojiler ile birlikte ise dikkat edilmesi gerekir. Biz bu makale ile azigos lobun oluşumunu ve literatürde birlikte tanımlanan patolojilerini vurgulamayı amaçladık. Anahtar KelimelerAzigos Lob; Azigos Ven; Anatomik AbstractThe knowledge of azygos lobe is important during thoracic surgical procedures. It is a rare anomaly in bronchopulmonary segmentation due to an unusual course of the azygos vein. There is no a pathological sense alone, if combined with other pathological events should be considered. We aimed to emphasize in this article the formation of the azygos lobe with described together pathologies in the literature.
