Figures
- Fig 1.
Sagittal T2-weighted images of the lumbar spine demonstrating multiple intradural flow voids (left, white oval), which appear on the surface of the conus (right, white arrows). No change in signal intensity was identified within the cord.
- Fig 2.
Precontrast (left) and postcontrast (right) axial T1-weighted images demonstrate an enhancing mass in the left L4 neural foramen (white arrows). The low signal intensity within the posterior aspect of the vertebral body enhanced after contrast administration, consistent with atypical hemangiomas.
- Fig 3.
Correlative coronal contrast-enhanced spinal MRA maximum intensity projection image (left) and late-phase anteroposterior conventional spinal angiogram (right) demonstrate a hypervascular mass (thin arrow) with radicular venous drainage (curved arrow). Prominent intradural veins are present, which ascend to the level of the conus, where prominent anterior and posterior pial veins (thick arrow) are visualized.
