Spinal magnetic resonance (MR) imaging of a 3-year-old girl with chronic inflammatory demyelinating polyneuropathy (CIDP) showed thickened and marked enhancement of the lumbosacral nerve roots. These abnormalities resolved after steroid treatment. MR imaging of the cauda equina may be helpful in the diagnosis of CIDP.

Sagittal fat-saturated T1-weighted images off the midline to the right (A), at the midline (B), and off the midline to the left (C). Chronic inflammatory demyelinating polyneuropathy (CIDP) in a 13-year-old boy with peripheral neuropathy and gait disturbance. D, E, F, and G, Axial postcontrast T1-weighted fat-saturated images through the lower thoracolumbar junction (D), conus medullaris (E), and nerve roots (F, G). The images show marked enhancement of the spinal nerve roots (arrows in A through F), with expansion of the nerve roots seen as they exit through the neural foramina (asterisks in F and G). This enlargement is typical of CIDP.
