High-resolution ultrasound in patients with Wartenberg’s migrant sensory neuritis, a case-control study

Wartenberg's migrant sensory neuritis (WMSN) is a rare and exclusively sensory neuropathy of unknown etiology, characterized by sudden numbness of one or multiple cutaneous nerves. Numbness may be preceded by pain in the area of distribution of the involved nerve. In some patients stretching of the affected nerve or moving the limb causes pain in the distribution of the involved nerve.(Nicolle et al., 2001; Stork et al., 2010, Wartenberg, 1958) Although any cutaneous sensory nerve can be involved, deficits most commonly reported involve the sensory branches of the peroneal nerve, the digital branches in the hands, the superficial radial nerve and the sural nerve.(Nicolle et al., 2001; Stork et al., 2010) The disease course is generally benign, usually recurrent, and the impact on daily life being limited.(Nicolle et al., 2001; Stork et al., 2010) An auto-immune etiology has been suggested, although patients who received immunomodulating treatment did not improve.(Nicolle et al., 2001; Simmad et al., 1999)
