NONINVASIVE characterization of spinal dural arteriovenous fistula is essential for guiding clinical management.

A 72-year-old woman was admitted to our hospital because of rapidly progressive paraplegia and sphincteric disturbances. T2-weighted magnetic resonance imaging showed intramedullary high-intensity areas. First-pass, contrast-enhanced 3-dimensional magnetic resonance angiography with short acquisition time demonstrated the enlarged draining medullary vein, providing correct localization (Figure 1, A). Subsequesnt conventional angiography results confirmed the diagnosis (Figure 1, B).

Figure appears in full text version. A, The enlarged draining posterior median vein was demonstrated with contrast-enhanced magnetic resonance angiography (white arrowheads). B, Digital-subtraction angiography of selective catheterization of the lumbar artery at the L2 level shows the radicular artery and enlarged drainer (black arrowheads).

Fast 3-dimensional contrast-enhanced magnetic resonance angiography is a noninvasive technique with high accuracy in the characterization of spinal dural arteriovenous fistula.¹ Visibility of the draining vein corresponds well with that of digital subtraction angiography, facilitating the management of . . .
