摘要：Multiple myeloma, a plasma cell neoplasm commonly targets bone, bone marrow, and the kidneys. We describe a 44-year-old female patient who presented with progressive weakness of left upper limb proceeding from distal towards proximal aspect over 3 months. The patient was diagnosed as immunoglobulin G (IgG) kappa multiple myeloma with plasmacytoma complicated with brachial plexus compression at C2 to C7 levels. The patient was treated with high dose steroids, palliative radiotherapy followed by bortezomib, lenalidomide and dexamethasone. Her disease progressed while on treatment and she succumbed to the illness three months later. Plasmablastic myeloma with brachial plexopathy as the sole initial manifestation is extremely rare and this possibility should be considered in the differentials in such presentation.
