Abstract
This report presents a patient with an intradural spinal arteriovenous fistula complicated
by infarction of the cord. The diagnosis of an arteriovenous malformation was made
on the magnetic resonance imaging (MRI) study with the demonstration of intraspinal
serpentine areas of low signal intensity (flow voids). The presence of other MRI findings
believed to represent spinal cord ischemia included multisegmental swelling of the
cord associated with T1 and T2 prolongation and gadolinium enhancement. The location
of the malformation, as well as arterial supply and venous drainage, were defined
on selective spinal arterial digital subtraction angiography (DSA). Following surgical
resection, the clinical condition stabilized, but with poor return of lost function.
The repeat MRI 6 months after surgery demonstrated diffuse thoracic cord atrophy.
