Multiple bilateral traumatic pulmonary pseuodocysts in a 53 year-old male diagnosed retrospectively.

Traumatic pulmonary pseudocyst (TPPC) is a rare complication, which might be encountered after thoracic trauma. It is most often (75-100%) seen in children and young adults. A 53 year-old male presented with multiple bilateral pulmonary cysts after a motor vehicle accident. We evaluated the patient for abscess, tuberculosis, and Wegener's granulomatosis with negative results. Follow up chest X-rays showed spontaneous resolutions of pseudocysts with replacement with pneumatocelae. In patients with recent chest trauma, TPPC should be kept in mind to prevent unnecessary invasive tests.
