- Abstract
- BACKGROUND Traumatic pulmonary pseudocyst (TPP) is a rare complication of blunt chest trauma and closely related with severe injury. However, it has been poorly documented. We present a retrospective review of TPP cases treated at our hospital. METHODS The medical records and chest computed tomography scans of patients with TPP treated from January 2010 to December 2013 were retrospectively studied. RESULTS A total of 978 patients underwent chest computed tomography for blunt chest trauma during the study period, and 81 (8.3%) had a total of 150 TPPs. The most common mechanism of injury was being struck by a motorized vehicle (n = 25, 30.9%). The mean (SD) Injury Severity Score (ISS) of the 81 patients was 33.2 (11.4). The prevalence of TPP was higher in younger patients (p = 0.011), but the total number of fractured ribs was significantly lower (p = 0.001). In a subgroup analysis performed according to pseudocyst location, the intraparenchymal group had more severe injuries than the subpleural group (ISS, 23.3 vs. 32.4, p < 0.001; chest Abbreviated Injury Scale [AIS] score, 3.4 vs. 4.0, p < 0.001; number of associated injuries, 2.9 vs. 4.0, p = 0.001). By multivariate analysis, ISS, age, and number of associated injuries were significantly different in these two groups (p = 0.038, p = 0.006, and p = 0.045, respectively). CONCLUSION The prevalence of TPP among cases of blunt chest trauma was 8.3% and was higher in those struck by a vehicle and younger patients. Intraparenchymal pseudocyst was found to be related to more severe injuries. TPP was a self-limiting condition that does not require specific treatment. Copyright © 2015 Wolters Kluwer Health, Inc.
