[Therapeutic implication of the azygos vein lobe in patients with pulmonary adenocarcinoma].
The azygos vein lobe is an anatomic variant reported in 0.1 to 8% of the population and results from an anomalous development of the right lung upper lobe. In the majority of the cases, clinical implications are lacking. Since the original description of a tumor of the azygos vein lobe, in 1969, only two more cases have been reported in the literature. Behind its rarity, a tumor with such location may pose some management implications. The authors report the clinical case of a 56 years old smoker man, in whom a chest x-rays revealed a poorly defined image in the upper lobe of the right lung. Complementary studies and evaluation allowed the diagnosis of pulmonary adenocarcinoma, adherent to the azygos vein, in a patient with azygos vein lobe. The authors emphasize the fact that despite the origin of the tumor being the lung, the presence of this anatomic variant of the azygos vein played a determinant role in the surgical approach.
