Ginkgo leaf sign (subcutaneous emphysema)

Last revised by Travis Fahrenhorst-Jones on 17 May 2022

The ginkgo leaf sign of the chest, also referred as the ginkgo leaf sign of subcutaneous emphysema, is a radiographic appearance seen with extensive subcutaneous emphysema of the chest wall. Gas outlines the fibers of the pectoralis major muscle and creates a branching pattern that resembles the branching pattern in the veins of a ginkgo leaf.

The ginkgo leaf sign is also used to describe the appearance of spinal meningiomas (ginkgo leaf sign - spinal meningioma).
