Ginkgo leaf sign - spinal(spinal meningioma)
Body
was changed:
The ginkgo leaf sign of spinal meningiomas (not to be confused with the ginkgo leaf sign of subcutaneous emphysema) has been described as a useful MRI sign in distinguishing a spinal meningioma from neurogenic tumour (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.
