BACKGROUND: Traumatic pulmonary pseudocysts or post-traumatic pneumatocoeles are a relatively rare-encountered condition occurring after trauma and an even rarer talked about subject. Most resolve within a few weeks, but if complicated by hematoma, may persist for months. This study intends to evaluate the resolution times of traumatic pulmonary pseudocysts and their clinical significance. METHODS: We report a case analysis of 12 cases from Hanyang University Guri Hospital dating from July 1997 through October 2004. RESULTS: The overall mean time for complete resolution was 85.6 days. The mean time for resolution for the uncomplicated traumatic pulmonary pseudocysts was 25.3 days (n=6) and the mean time for resolution for the complicated (blood filled) traumatic pulmonary pseudocysts was 145.8 days (n=6). When resolution times were compared according to size, those less than 2 cm showed a mean resolution time of 23.6 days (n=5) and those greater than or equal to 2 cm showed a mean resolution time of 129.9 days (n=7). CONCLUSIONS: Comparisons between completely blood-filled pseudocysts and uncomplicated pseudocysts have shown statistically significant differences in resolution times. Statistical significance has also been found between pseudocysts of sizes less than 2 cm and those greater than or equal to 2 cm. Conservative treatment is generally the rule; close follow-up and symptomatic treatment are necessary.
