The aim of this retrospective study was to report the clinical presentations, diagnosis, complications and treatment for a series of TPPs at a hospital in Turkey. The charts of 996 patients who were admitted for thoracic trauma between 1999 and 2012 were retrospectively reviewed. Fifty-two patients had TPPs, and the data collected for these individuals were sex, age, and type of trauma (blunt and/or penetrating). Univariate analysis of categorical data was performed using Pearson's Chi square test. Results for continuous variables were statistically compared using the Mann-Whitney U test. The patients were 42 males and 10 females aged 12-72 years (mean age 33.1 years). Forty-one had blunt trauma and 11 had penetrating trauma. There was no significant difference between the proportion of blunt trauma patients who developed TPP (41/761, 5.3 %) and the proportion of penetrating trauma patients who developed TPP (11/235, 4.6 %) (p > 0.05). All 42 patients had pulmonary contusion. Only 10 patients (19.2 %) had TPP identified on their chest X-ray, and thoracic computed tomography revealed TPP clearly in all these cases. Forty-two patients (80.7 %) were diagnosed with TPP on day 1 post-trauma. The hospital stays ranged from 2 to 35 days for the patients with blunt-trauma, and from 4 to 15 days for those with penetrating trauma (means 8.8 and 8.0 days, respectively; p > 0.05). Only one patient required thoracotomy for a pseudocyst that did not resolve and became progressively enlarged. This TPP was resected at 6 months post-trauma. One patient died on day 9 post-trauma due to multiple organ failure. The other 40 pseudocysts resolved spontaneously within 1-5 months. Traumatic pulmonary pseudocysts are pulmonary lesions that occur after either blunt or penetrating trauma and tend to be overlooked. Most of these lesions are self-limiting, benign lesion.eninfo:eu-repo/semantics/closedAccessChest traumaPulmonary pseudocystArticle4121811882603826310.1007/s00068-014-0427-22-s2.0-84939880223Q2WOS:000351908000010Q4
