Temporary multiple cranial nerve palsies in a patient with type 1 diabetes mellitus

Remittent isolated palsy of peripheral or of upper cranial nerves in diabetic patients is well documented, but paralysis of a lower cranial nerve or an isolated branch of any cranial nerve has rarely been reported. In the case described, besides temporary hypoglossal and facial nerve palsies previously, unilateral temporary vocal cord palsy caused by right inferior laryngeal nerve (recurrent) paralysis associated with type 1 diabetes mellitus is presented. Hoarseness and vocal cord palsy of the patient, as in the case of her first admission with other complaints due to other cranial nerve palsies, totally remitted, presumably both owing to improved metabolic control.
