“…Chronic obstructive pulmonary disease, asthma, infection, inflammation, neoplasm, chronic steroid use, and severe coughing are examples of potential risk factors. Lung hernias have been previously reported in case reports and case series [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. However, there is a paucity of original research studies regarding lung herniation.…”

Background: Lung herniation has been described in case reports or series. There are scare data in the form of original research studies to systematically evaluate this condition. Objective: Our aim was to evaluate lung hernias with a focus on their natural history. Methods: This is a retrospective study at our institution of patients who were found to have lung herniation on imaging between September 2010 and November 2022. Electronic medical record review was performed to extract clinical information regarding patients. Computed tomographic imaging was used to evaluate hernia size and size progression over time with a median follow-up time of 3.8 years. Results: Thirty-eight patients were eligible for analysis. Majority of patients were overweight or obese (31/38), smokers (31/38), had prior thoracic surgery (30/38), and were asymptomatic (33/38). Twenty of 38 patients had stability in hernia size, 12 of 38 patients had hernia size progression, and 6 of 38 patients showed hernia size regression. Younger age was found to be predictive of hernia size progression with age of 60 years being the cut-off for its prediction. Conclusion: Lung hernias typically either remain stable in size or show size progression. Younger age (60 years cut-off) was found to be predictive of size progression. This is the largest systematic investigation at a medical institution to the best of our knowledge of lung hernias which used computed tomographic imaging to follow up lung hernias. Further information could be given to patients with this condition and to clinicians for potential management guidance.
