Evaluation of nerve roots with 3D Cube T2
Also known as Hereditary Motor-Sensory Neuropathy and Charcot-Marie-Tooth,
Hypertrophic Neuropathy (HN) is a hereditary disorder that affects peripheral
nerves characterized by focal or diffuse nerve enlargement.
MR findings include T1 hypointense and T2 hyperintense fusiform mass of peripheral
nerves with or without cauda equine nerve involvement. These masses can show
abnormal contrast enhancement. Therefore, high-resolution MR imaging is
recommended for diagnosis.
Differential diagnosis include Guillain-Barré syndrome, chronic inflammatory
demyelinating polyradiculoneuropathy and nerve sheet tumor.

pain. MR study was performed looking for degenerative changes and lumbar
