case_images: The enhanced MRI of the brain showed diffuse pachymeningeal enhancement consistent with SIH [Figure 1].
case_images: Xpert CT during digital subtraction myelogram showing contrast enhancement along the right L2 nerve root (dashed line) concerning for cerebrospinal fluid venous fistula.

case_images: However, the MR myelogram with digital subtraction images finally correctly documented a right-sided CVF at the L2 level [Figure 2].
case_images: Angiographic images (AP view [a] and lateral view [b]) that show the embolization of the cerebrospinal fluid-venous fistula using ONYX. The dashed circle on the lateral view indicates the location of the nerve root.
