Abstract
A 64-year-old man presented with left upper limb weakness and dysesthesia for 4 months. Magnetic resonance imaging demonstrated swelling from the 6th-8th left cervical nerve roots to the left brachial plexus. The serum IgG4 level was elevated (762.7 mg/dL). 18F-FDG-PET showed high uptake in the mediastinal lymph nodes, and biopsy revealed infiltration of IgG4-positive plasma cells. We diagnosed IgG4-related neuropathy, and steroid therapy administration improved the symptoms. IgG4-related disease should be considered in the differential diagnosis of peripheral nerve swellings. If biopsy of the disordered nerves is difficult, lymph nodes or other organs should be considered.
期刊介绍：
This new peer-reviewed online-only journal publishes original case reports covering the entire spectrum of neurology. Clinicians and researchers are given a tool to disseminate their personal experience to a wider public as well as to review interesting cases encountered by colleagues all over the world. To complement the contributions supplementary material is welcomed. The reports are searchable according to the key words supplied by the authors; it will thus be possible to search across the entire growing collection of case reports with universally used terms, further facilitating the retrieval of specific information. Following the open access principle, the entire contents can be retrieved at no charge, guaranteeing easy access to this valuable source of anecdotal information at all times.
