Lumbar to pelvic simple MRI images were taken of (a) and (b) on the 6th day of illness, (c) on the 13th day of illness, and (d) 1 month after discharge.(a) T2-emphasized image: A hyperintensity of marginalization is observed at 2 cm in the right erector spinae muscle (black circle). (b) Diffusion-weighted image: hyperintensity is observed in the posterior to the spinal canal from L4 vertebral body to the sacral region (white circle), (c) T2-enhanced image: paraspinal muscle abscess (white arrow) and epidural abscess (black triangle) tend to shrink, and (d) T2- emphasized image: it is confirmed that the image has completely disappeared.

The T2-enhanced image indicated hyperintensity of marginalization at 2 cm in the right erector spinae muscle, while the diffusion-enhanced image indicated hyperintensity in the posterior to the spinal canal from L4 vertebral body to the sacral region [Figures 1a and b]. A simple MRI of the lumbar spine to pelvic was taken on the 13th day of onset, confirming the reduction of the abscess [Figure 1c]. One month after discharge from the hospital, another simple MRI of the lumbar spine to pelvic was performed, which confirmed the disappearance of the abscess [Figure 1d].
