Bilateral pneumothoraces after unilateral transthoracic needle biopsy of a lung nodule.

The occurrence of pneumothorax after an invasive transthoracic procedure is a well-known complication. Less well-recognized is the occurrence of bilateral pneumothoraces after a unilateral intervention with a potential for life-threatening consequences in patients who have undergone median sternotomies. We present a patient who had undergone a thymoma resection in the remote past and developed bilateral pneumothoraces after undergoing transthoracic needle biopsy of a right lung nodule.
