The enhanced MRI of the brain showed diffuse pachymeningeal enhancement consistent with SIH [Figure 1].

However, the MR myelogram with digital subtraction images finally correctly documented a right-sided CVF at the L2 level [Figure 2].
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.
