MR imaging in hypertrophic neuropathy: a case of hereditary motor and sensory neuropathy, type I (Charcot-Marie-Tooth).

We describe findings of Charcot-Marie-Tooth disease in magnetic resonance imaging (MRI). The MRI examination of the lumbar spine with and without gadolinium DTPA showed diffusely enlarged cauda equina, nerve roots, and ganglia. In the setting of appropriate family history and clinical presentation, the findings of diffusely enlarged nerve roots support the diagnosis of hereditary motor and sensory neuropathy, Type I (HMSN I, Charcot-Marie-Tooth).
