Magnetic resonance imaging findings in chronic inflammatory demyelinating polyneuropathy with intracranial findings and enhancing, thickened cranial and spinal nerves.

Chronic inflammatory demyelinating polyneuropathy is a rare autoimmune disorder characterized by chronically progressive or relapsing symmetric sensorimotor involvement. We describe the imaging findings in our patient. Magnetic resonance imaging showed presence of an intracranial white matter lesion and enhancing, thickened cranial and spinal nerves. This disorder has been described very infrequently in the radiology literature.
