Ginkgo leaf sign (subcutaneous emphysema)

Last revised by Arlene Campos on 19 Jan 2024

The ginkgo leaf sign of the chest, also referred to 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).
