[Post-traumatic pulmonary pseudocysts].

BACKGROUND

Pulmonary pseudocyst is an unusual complication of chest trauma.

CASE REPORT

A 12-year-old boy suffered from a non penetrating chest trauma. Examination was normal except mild hemoptysis. Chest X-rays and tomodensitometry showed several cystic lesions surrounded by areas of pulmonary contusion in the right lower lobe. X-rays performed a few years before the trauma were normal. The cystic lesions progressively disappeared within a few months.

CONCLUSION

This is a new case of post-traumatic pulmonary pseudocyst whose diagnosis may be difficult until spontaneous cure.
