Bamboo Leaf Sign as a Sensitive Magnetic Resonance Imaging Finding in Spinal Subependymoma: Case Report and Literature Review

Figure 4

Schematic representation of MRI findings for spinal subependymoma demonstrating the bamboo leaf sign. (a) Other intramedullary tumors like ependymoma and astrocytoma show gradual dilatation of the spinal cord. (b) Spinal subependymoma shows steep swelling of the spinal cord due to subpial growth. (c) Blue dashed line shows sagittal section for MRI of the spinal subependymoma. (d) Sagittal T2WI of subependymoma showing bamboo leaf sign. T, tumor; P, pia mater.
