A 54 year old female with bilateral traumatic pulmonary cyst due to agricultural accident is reported.
She was run over by a tractor and admitted to our hospital in forty minutes after injury.
Her X-ray film on 7 th day revealed bilateral pulmonary cyst and intrapulmonary hematoma.
But, these abnormal shadows disappeared completely on 70 the day after injury.
We consider that operative treatment for the traumatic lung cyst or intrapulmenary hematoma is not need unless we can find the conditions that give a positive support to thoracotomy.
