Table 3 The percentage residual radioisotope activity in the CSF (% ± SD) in patients with differing degrees of post lumbar headache at 1 h, 3 h, 5 h, and 24 h after injection.

  1. PLH(-): headache of usual severity or less; PLH(±): headache of usual severity or less headache, but with other aggravating symptoms; PLH(+): headache increased after lumbar puncture; PLH(2+): headache more severe than or equal to the most severe headache ever experienced. The (+) and (2+) groups tended to have more CSF leakage but the differences were not significant.
