A 53 years old male, a known case of ankylosing spondylitis having recurrent attacks of hypoglycaemia, developed symmetrical distal sensorimotor neuropathy. The neuropathy was axonal with secondary demyelination. Evidence of vasculopathy was also noted on histopathology of the nerve. Serum C-peptide level was low, a feature reported with autoimmune hypoglycaemia with antireceptor antibodies. The patient showed spontaneous recovery.
