Introduction:
Spontaneous pneumothorax recurs in 30-54% of patients without surgery. Identifying individuals likely to suffer a recurrence, who might benefit from pre-emptive surgery, is challenging. Previous meta-analysis suggested a relationship between contralateral recurrence and specific CT findings.
Methods:
We analysed CT images and recurrence rates of 243 patients seen by our tertiary referral pneumothorax service.
Results:
We validated the meta-analysis observation that contralateral lung cysts are associated with a higher risk of contralateral recurrence in younger individuals. Furthermore, we observed that the size of contralateral cysts to be associated with increased contralateral recurrence in younger patients.
Conclusion:
The detection of contralateral lung cysts might therefore help identify younger patients more likely to benefit from pre-emptive surgery.
