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).
