New perspectives for a huge traumatic pneumatocele treatment in a young adult.

Traumatic pneumatocele (TP) is a very rare condition that occurs mostly in children and young adults. Conservative treatment is full-fledged for uncomplicated cases. We presented here an 18-year-old young adult with chest trauma caused by a fall. Chest computed tomography disclosed a cavitary lesion 10.5 × 8.5 × 6.4 cm over right upper lobe (RUL) with bilateral lower lung contusion and a mild haemopneumothorax but without rib fractures. Under conservative treatment, the condition lasted for ~8 months before complete resolution. Detailed temporal changes in chest X-ray were recorded for the analysis of natural healing processes.
