A Spinal Arteriovenous Fistula in a 3-Year Old Boy
Figure 1
Thoracolumbar MRI scans, midsagittal views, and T2 weighted images: (a) scan at presentation of the child shows the dilated vascular intraspinal structures and the large aneurysm (arrow) nearly completely involving the spinal canal at the level of T12 with spinal cord compression; (b) scan after second embolisation shows the haematoma (dark) in the lower spinal canal, a decrease in size of the dilated intraspinal blood vessels, the occluded large aneurysm and the spinal cord oedema/hyperintense lesions of the lower spinal cord; (c) scan after surgery shows the resected aneurysm, with a very thin and split spinal cord at level T12, residual intraspinal haematoma, some dilated thrombosed intraspinal vessels, and spinal cord oedema/hyperintense lesions of the lower spinal cord; (d) scan two months after treatments shows a resolving of the haematoma, unchanged thrombosed intraspinal vessels, and a decrease in oedema/hyperintensity of the lower spinal cord.
