A 25-year-old woman presented with a 10-year history of frequent falls and deafness. Her mother had a similar neurologic picture. Examination showed peroneal amyotrophy, pes cavus, and hearing loss. Magnetic resonance (MR) neurography showed diffuse nerve enlargement in the lower limbs (figure). Genetic analysis revealed heterozygous mutation c.82T>C (p.Trp28Arg) in the PMP22 gene, defining diagnosis of Charcot-Marie-Tooth disease (CMT) type 1A.
