Diagnosing chronic inflammatory polyradiculopathy in patients with pre-existing diabetic sensorimotor polyneuropathy is a diagnostic challenge. We present a case of a 69 years old who presented with weakness of legs for two months,he was diagnosed as having CIDP on the background of diabetic sensorimotor polyneuropathy, further and extensive workup revealed the final diagnosis of nonsecretory myeloma. Diagnosing non secretory myeloma is itself a diagnostic challenge and usually first line investigations for the workup of myeloma are negative as was the case in our patient. Our patient with CIDP had raised free light chains of kappa which made the final diagnosis of kappa associated plasma cell dyscrasia.
