Chronic inflammatory demyelinating polyneuropathy after Campylobacter jejuni infection mimicking vasculitic mononeuritis multiplex in a diabetic.

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a clinically heterogeneous disorder. Recent reports suggest that CIDP could be more frequent in diabetics. We report here a case of CIDP presenting as mononeuritis multiplex with accompanying cranial nerve involvement in an insulin-dependent diabetic who presented a preceding Campylobacter jejuni infection and misleading skin lesions. Treatment with intravenous immunoglobulins was successful. This case suggests that CIDP should be considered as a potential diagnosis in all diabetics with localized, acute or sub-acute onset, and multiple, or overlapping mononeuropathies.
