case_images: The MRI myelogram shows an abnormal fluid signal intensity in the left lumbar area, along the left paraspinal muscle and soft tissues at the L3-4-5 level, probably due to CSF leakage.

case_images: The patient's postural headaches persisted for 4 days, so we decided to perform a transforaminal EBP at the L3-4 and 4-5 levels on the left side, the site of leakage in the MRI myelogram (Figure 1).

case_images: Under fluoroscopic guidance, a 22-gauge needle (Hakko, Japan) was inserted with a transforaminal approach and then contrast was injected at the left L3-4 and L4-5 levels (Figure 2).
