Ginkgo leaf sign (spinal meningioma)

Dr Craig Hacking and A.Prof Frank Gaillard et al.

The ginkgo leaf sign of spinal meningiomas has been described as a useful MRI sign in distinguishing a spinal meningioma from neurogenic tumor (e.g. spinal schwannoma). 

It is seen on axial post contrast T1 imaging, with the leaf representing the distorted spinal cord, pushed to one side of the theca by the meningioma, and the stem, seen as a non-enhancing 'streak', probably representing the stretched dentate ligament 1

The ginkgo leaf sign is also used to describe the appearance of chest wall surgical emphysema (ginkgo leaf sign(chest)).
