Hypertrophic nerve roots in a case of Roussy-Lévy syndrome

Hypertrophic radiculopathy is a rare feature of neuropathies. Single cases of enlarged nerve roots have been described in hereditary motor sensory neuropathies (HMSN) and chronic inflammatory demyelinating diseases (CIDP). This is the first description of hypertrophied nerve roots in a patient with Roussy-Lévy syndrome. MRI did not show contrast enhancement of the enlarged nerve roots or nodular lesions.
