Case Discussion

In the extensive subcutaneous emphysema, air outlines the major pectoralis muscle fibers and creates a branching pattern known as Ginkgo leaf sign.

The ginkgo tree is native to china and has fan shaped leaves with prominent visible veins.  The air between the muscle fibres of the pectoralis muscle mimic the appearances of these veins.
