4 | CONCLUSION
SDAVF is an uncommon condition primarily impacting the spinal cord, characterized by venous congestion of the spinal cord stemming from a dural arteriovenous fistula. Although it may present with symptoms of intermittent lameness, it may not have typical symptoms because of its gradual progression. As in this case, this condition is often misdiagnosed as a lumbar spine disease, such as lumbar degenerative disease, by missing abnormal signals in the conus medullaris on the initial lumbar MRI. Imaging plays a crucial role in achieving a precise diagnosis, with T2-weighted images proving particularly valuable for the diagnosis of SDAVF. MRI sagittal sections show high signal intensity of the spinal cord and dilated spinal veins in the subarachnoid space. The treatment options encompass both direct microsurgery and endovascular embolization. Because SDAVF is treatable, early detection using diagnostic imaging is important.
