Their etiology remains unknown, although unrecognized local trauma may precipitate SIH. In addition, they are diagnostically challenging despite various imaging tools available. Here, we present CVF identification using magnetic resonance myelography (MRM) and elaborate on their surgical management techniques.<\/jats:p><\/jats:sec><jats:sec id=\"st2\"><jats:title>Methods:<\/jats:title><jats:p>Retrospective charts of confirmed and treated CVF patients with attention to their diagnostic imaging modalities and management techniques were further reviewed.<\/jats:p><\/jats:sec><jats:sec id=\"st3\"><jats:title>Results:<\/jats:title><jats:p>Six cases were identified of which three are presented here. There were two females and one male patient. All had fistulas on the left side. Two were at T7-T8 while the third was at T9-T10 level. Two underwent hemilaminotomies at the T7-T8 while the third underwent a foraminotomy at T9 level to access the fistula site. All CVF were closed with a combination of an aneurysm clip and a silk tie. On follow-up, all had complete resolution of symptoms with no evidence of recurrence.<\/jats:p><\/jats:sec><jats:sec id=\"st4\"><jats:title>Conclusion:<\/jats:title><jats:p>Of the various imaging modalities available, MRM is particularly sensitive in localizing CVF spinal nerve level and their laterality.
