case_images: Brain MRI showed peri hemispheric, subdural fluid collections, up to 4 mm thick [Figure 1]; reduced distance between the pons and the mammillary bodies to 4 mm, cerebellopontine angle reduced to 55 , and interpeduncular angle reduced to 51 .
case_images: CT myelography showing the CSF leakage on the TH12/ L1 level (arrow) on the right side, frontal plane.

case_images: CT myelography with subdural administration of contrast mixed with saline in a ratio of 40/60 showed the fluid leakage site through the spinal nerve root sheath at the level of Th12/L1 intervertebral foramen on the right side [Figures 2 and 3].

case_images: CT myelography with subdural administration of contrast mixed with saline in a ratio of 40/60 showed the fluid leakage site through the spinal nerve root sheath at the level of Th12/L1 intervertebral foramen on the right side [Figures 2 and 3].

case_images: After confirmation of level Th12/L1 in the CT scout image, we, then, inserted 18G lumbar puncture needle to the intervertebral foramen Th12/L1 under the guidance of CT [Figure 4].
case_images: EBP under CT guidance, root sheath covered with patient's venous blood (area in the circle).

case_images: Having previously taken 10 ml of the patient's venous blood, we, then, injected it at the root exit site of the intervertebral foramen under CT guidance [Figure 5].
case_images: CT scan performed 1 month after the EBP under CT guidance, complete disappearance of the fluid collections (arrowheads).

case_images: During the follow-up visit, 1 month after hospitalization, the patient was completely free of headache and we found normalization of MRI image [Figure 6].
