A 40-year-old male consulted complaining of progressive dys- pnea worsening over the last 4 years. During history, the patient mentioned motor-vehicle incidents at the ages of 6 and 12 years and posteriorly left diaphragmatic paralysis at 14. In 2019, he was hospitalized on the grounds of a respiratory infection. Upon pul- monary auscultation, borborygmi were found. A thoracoabdominal Computed Tomography (CT) was taken, revealing a diaphragmatic hernia of approximately 6.5 cm × 4.5 cm. The hernial sac contained abdominal viscera in the left hemithorax. A comparison of the 2023 CT scan with the one obtained in 2019 demonstrates progression of the herniation.
