Figure 2.

Distribution of spinal CSF leakages. In general, periradicular leaks were most commonly seen around the upper lumbar region (A), epidural collections were mainly distributed between middle thoracic to upper lumbar regions (B), and retrospinal collections were primarily seen in the lower lumbar region (C). When analysed separately, patients with post-dural puncture headache (D and E) had more rostral distributions of periradicular leaks (D and F) and epidural collections (E and G) than those without (F and G).
