Azygos Lobe in a 38-Year-Old Male Donor Diagnosed with Ogilvie’s Syndrome
The azygos lobe (AL), an additional lung lobe most commonly found in the right apical lung region, is a rare anatomical variant present in approximately 1% of the population. It is embryological in origin and may form if the azygos vein fails to migrate medially over the lung. While it is normally clinically silent, it can have surgical and clinical implications. An AL can be the source of infection or disease, such as squamous cell carcinoma, and can also compress the upper lobe and lead to obstruction, infarction, and necrotic tissue. Additionally, it can present as an unforeseen surgical obstacle, specifically during a thoracotomy, and can be mistaken for a thoracic mass on radiographic imaging, potentially leading to unnecessary interventions. In this case report, a 38-year-old male donor with a history of Ogilvie’s syndrome, multiple traumatic brain injuries (TBIs), and chronic respiratory failure presented with an AL during routine donor dissection. The cause of death was listed as prostate cancer, hypertension, atrial fibrillation, and type II diabetes mellitus. The AL, located on the posterior apical surface of the right lung, measured 5 cm in width and 8 cm in length. The left lung showed signs of atrophy and discoloration, possibly the result of pollution exposure or smoking earlier in life. In this article, we describe the incidence, historical classification, embryology, and physiology associated with an AL and its clinical implication for this donor.
