Abstract

BACKGROUND:

Traumatic pulmonary pseudocysts are rarely talked about, developing in less than 3% of patients with pulmonary parenchymal injuries. Resolution usually occurs within a few weeks to a few months.

METHOD:

A prospective study was undertaken in 21 cases treated in Menoufia University Hospital, Egypt from August 2011 through August 2013.

RESULTS:

The overall mean time for complete resolution was 61.1 days. The mean time for resolution of simple traumatic pulmonary pseudocysts was 21 days (n = 6), and the mean time for resolution of complicated (blood filled) traumatic pulmonary pseudocysts was 77.1 days (n = 15). Mean resolution time was 26.3 days for small pulmonary pseudocysts ≤22 mm (n = 11) and 99.4 days for those >22 mm (n = 10). The resolution time was 42.6 days in patients 17-years old or younger (n = 11) and 81.4 days in patients older than 17 years (n = 10).

CONCLUSION:

There was a highly significant difference in resolution time between simple and complicated pseudocysts. There was also a highly significant delay in the resolution time of pseudocysts larger than 22 mm and in patients older than 17 years.
