Over the next 4\u2005years, she had three further episodes of excruciating back pain accompanied by raised CSF protein, but without weakness, sensory loss, or abnormalities in routine nerve conduction studies. Sensory evoked potentials suggested proximal demyelination and lumbosacral plexus imaging suggested inflammation. We argue that this is a relapsing proximal polyradiculoneuropathy on the spectrum of chronic inflammatory demyelinating polyradiculoneuropathy.<\/jats:p>","DOI":"10.1136\/practneurol-2016-001397","type":"journal-article","created":{"date-parts":[[2016,6,16]],"date-time":"2016-06-16T22:39:35Z","timestamp":1466116775000},"page":"488-492","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["CIDP
