Computed tomography (CT) myelograms showing spontaneous spinal cerebrospinal fluid (CSF) leaks. (a) Bilateral CSF leaks (arrows) at L2-3 levels. (b) A contrast-filling nerve root sheath (arrows) at left T12-L1 level. (c) A coronal reconstruction image showing bilateral contrast-filling nerve root sheaths (arrows) at T1 level. (d) A small amount of contrast leak (arrow) in left T10 epidural space.

However, a prominent CSF leak was noted bilaterally at the level of L2-3 (Figure 1(a)) and contrast-filling nerve root sheath was identified at left T12 (Figure 1(b)), left L1 (Figure 1(c)), and bilateral T1. T10 level (Figure 1(d)). There was no pseudomeningocele or CSF leak at the laminectomized L4-5 level.
