“…Risk factors for SDAVFs include male sex, older age, hypertension, and a history of spinal trauma or surgery [ 8 ]. Diagnosis of SDAVFs typically involves magnetic resonance imaging (MRI) and spinal angiography [ 9 ]. Spinal angiography is considered the gold standard for diagnosis and allows for visualization of the fistula and its blood supply.…”

Spinal Dural Arteriovenous Fistula (SDAVF) is a rare and complex vascular condition with significant neurological consequences if left untreated. We present a case of SDAVF in a 46-year-old male who presented with progressive myelopathy. The patient presented with a three-month history of progressive lower extremity weakness, numbness, urinary retention, constipation, and gait disturbance. The spine's magnetic resonance imaging (MRI) showed diffuse T2 hyperintensity and contrast enhancement from T11 to L1, raising the suspicion of an intradural spinal cord lesion. Further evaluation with spinal angiography revealed an SDAVF at the level of T11-T12. The patient underwent surgical resection of the fistula, His lower extremity weakness and numbness improved significantly after surgery, and he was discharged with a plan for close follow-up. Early diagnosis and appropriate treatment prevent neurological deficits and improve patient outcomes. Surgical resection of the fistula can significantly improve neurological symptoms and should be considered a treatment option for SDAVF.
