Radiograph revealed extensive subcutaneous emphysema over the right chest wall. The fibers of the pectoralis major muscle are noticeable due to the free gas in the tissue, giving it the appearance of a ginkgo leaf (ginkgo leaf sign).
There is a right pneumothorax that is marked by the visible right pleural edge.
The mediastinum is not shifted (no evidence of tension).
Case Discussion
The ginkgo leaf sign is sometimes observed in patients with extensive subcutaneous emphysema. It is characterized by the visualization of the fibers of the pectoralis major muscle.
