OBJECTIVE: Although @entity450 is considered to be a major cause of progressive @entity602 in @entity1 with spinal dural arteriovenous fistulae (DAVFs), the @entity16 in @entity1 with spinal intradural @entity2758 ( @entity2758 ) has been attributed to @entity548 or to vascular steal. To reexamine this theory, we analyzed our own cases of @entity455 . METHODS: In 24 @entity1 with @entity455 , those who demonstrated progressive @entity602 with T2 hyperintensity in the spinal cord on magnetic resonance imaging (MRI) were diagnosed as @entity1 with congestive @entity602 . We further examined the clinical courses, MRI findings, and reversibility of these cases. RESULTS: @entity450 was judged to be a cause of @entity16 in 13 @entity1 (7 DAVFs, 6 intradural @entity2758 ). The T2 signals on these @entity1 ' MRI scans were located in the center and extended over several levels not corresponding to distribution of @entity63 due to arterial steal. Of the @entity1 who were diagnosed with congestive @entity602 , no differences between those with DAVFs and those with intradural @entity2758 were apparent in terms of clinical manifestations and reversibility. Eight (four DAVFs, four intradural @entity2758 ) of 13 @entity1 experienced @entity16 after treatment. All @entity1 with poor outcomes had intervals from onset of more than 3 years and showed contrast enhancement of the spinal cord on MRI studies. CONCLUSION: Spinal intradural @entity2758 as well as spinal DAVFs can be a cause of @entity450 . Regardless of its etiology, congestive @entity602 is potentially reversible if properly diagnosed and treated.

@entity450 is a major cause of XXXX in @entity2758 .
