Venous infarction of the spinal cord from a spinal AVF

Sagittal T2-weighted MRI image (A) shows hyperintensity in the lower half of the thoracic spinal cord (arrows). Axial turbo spin-echo T2-weighted MRI images (B, C, D) shows hyperintensity in greater than half of the spinal cord in a pattern atypical for arterial infarction (smaller arrowhead) as well as linear hypodensities in the subarachnoid space consistent with small vessels (short arrows). Spinal angiogram (E) shows catheter (thick arrow), spinal dural AVF (dashed arrow), and dilated intradural veins (larger arrowheads).
