Introduction: the azygos vein gives its name to a complex vascular system, located in the mediastinum, composing a blood route parallel to the inferior vena cava. This is why it represents an alternative route to venous drainage of the inferior vena cava territory in certain pathologies. The vein ends on the superior vena cava, at the level of the fourth thoracic vertebra, after performing a staff from the posterior mediastinum to the anterior, in intimate relationship with the inner face of the right lung. Material and Method: A cadaveric case of a malformation in the pathway of the azygos vein is reported in an adult cadaver previously fixed in solution based on formaldehyde. The dissection was carried out in the Anatomy Department during a routine dissection in the chest region. Results: it was found that the azygos vein arch had an intraparenchymal path in the right lung, generating a separation of the parenchyma from the pulmonary vertex to the vein. The arch was found at its usual vertebral level and it opened as described in the literature. Discussion: The lobe of the azygos vein is a congenital malformation caused by an alteration in the embryonic development of the azygos vein which, on its descent into the thorax, drags a portion of visceral pleura and penetrates the right upper lobe generating an anomalous fissure and therefore delimiting an accessory lobe. According to most of the authors, it is a rather frequent malformation, representing 0.4% of chest radiographs. Conclusion: A cadaveric case with the existence of the azygous lobe is reported, contributing one more tool to the anatomical and imaging scientific discussion. |

Introducción: la vena ácigos da nombre a un complejo sistema vascular, ubicado en el mediastino, componiendo una ruta sanguínea paralela a la vena cava inferior. Es por esto que puede ser una vía alternativa al drenaje venoso del territorio vena cava inferior en ciertas patologías. Su terminación se da sobre la vena cava superior, a la altura de la cuarta vertebra torácica, luego de realizar un cayado desde el mediastino posterior al anterior, transcurriendo en íntima relación con la cara interna del pulmón derecho. Material y Método: Se reporta un caso cadavérico de una malformación en el trayecto del cayado de la vena ácigos en un cadáver adulto fijado previamente en solución en base a formaldehido. La disección fue llevada a cabo en el Departamento de Anatomía durante una disección de rutina en la región del tórax. Resultados: se encontró que el cayado de la vena ácigos se daba en forma intraparenquimatosa en el pulmón derecho, generando una separación de dicho parénquima desde el vértice pulmonar hasta la situación de la vena. El cayado se daba a la altura vertebral habitual y su desembocadura era según la descrita. Discusión: El lóbulo de la vena ácigos es una malformación congénita producida por una alteración en el desarrollo embrionario de la vena ácigos que, en su descenso hacia el tórax, arrastra una porción de pleura visceral y penetra en el lóbulo superior derecho generando una cisura anómala y por tanto delimitando un lóbulo accesorio. Según la mayoría de los autores se trata de una malformación frecuente, representando el 0,4% de las radiografías de tórax. Conclusión: se reporta un caso cadavérico de existencia de lóbulo ácigos, aportando una herramienta más a la discusión científica anatómica e imagenológica.
