“…AL combined with PAPVR is a relatively rare variation in RUL, which is usually diagnosed incidentally on imaging in asymptomatic. The AL results from a failure of the normal migration of the AV from the thoracic wall to its usual position at the tracheobronchial angle, such that the fissure of the parietal and visceral pleura remain invaginated, which forming a cavity with the AV at its base [ 1 , 4 ]. Furthermore, the potential cavity would not cause adhesion to the AL [ 5 ].…”

“…The azygos lobe (AL), caused by azygos vein (AV) migrating abnormally from thoracic wall to tracheobronchial angle, is a rare variantion in the right upper lobe (RUL) [ 1 ]. Partial anomalous pulmonary venous return (PAPVR) is a less uncommon congenital pulmonary venous anomaly that involves drainage of 1 to 3 pulmonary veins into the right-sided circulation [ 2 ].…”

Background The azygos lobe (AL) combined with partial anomalous pulmonary venous return (PAPVR) is comparatively uncommon as well as in radical surgery for right lung cancer. Case presentation We herein present an extremely rare case of lung cancer coexisting with AL and asymptomatic PAPVR, which was diagnosed with preoperative contrast three-dimensional reconstruction and received radical surgery by thoracoscopy. During the surgery, we preserved azygos vein successfully and found a split type of PAPVR in right upper pulmonary vein. Conclusions AL combined with PAPVR may cause confusion on the vascular separation and disconnection of the right pulmonary hilar. However, preoperative 3D reconstruction is more conducive to the correct performing of this type of surgery.

“…AL combined with PAPVC is a comparatively uncommon variation in RUL, which is usually diagnosed incidentally on imaging with asymptomatic. The AL results from a failure of the normal migration of the AV from the thoracic wall to its usual position at the tracheobronchial angle, such that the ssure of the parietal and visceral pleura remain invaginated, thus forming a cavity with the AV at its base [1,4] .

The prevalence of the azygos lobe: A meta‐analysis of 1,033,083 subjects

et al. 2021

The azygos lobe (AL) is an accessory lobe of the right lung with prevalence between 0.4 and 1.2%. The aim of the present review is to provide a better estimate of the frequency of the AL and to examine its relationships with other variables such as population, diagnostic methods, and co-occurring illnesses. Studies published between 1899 and October 2020 were searched through three electronic databases; Google Scholar, PubMed, and JSTOR. Titles, abstracts, and full texts of the retrieved entries were screened to determine their appropriateness for inclusion. A total of 88 studies relating to 1,033,083 subjects met the inclusion criteria. A random-effects meta-analysis yielded an overall prevalence of 0.30% (95% CI: 0.0024-0.0035, I 2 = 97.9%). Linear regression and subgroup analysis revealed a negative correlation (ρ = À0.540, p <0.001) between AL prevalence and sample size; studies with smaller sample sizes had higher prevalences. The AL prevalence in individuals with congenital pulmonary defects, 5.2% (95% CI: 0.0018-0.0086, I 2 = 0%), was 17 times higher than the overall prevalence (z = 6.65, p <0.001), suggesting associations with other abnormalities and possibly a genetic predisposition. In addition to an evidence-based synthesis of AL prevalence, this study demonstrates publication bias and small-study effects in the anatomy literature. Awareness of the AL is crucial for radiologists when they interpret unusual radiological findings and for surgeons when they operate in the region.
