Résumé
Lambert-Eaton myasthenic syndrome (LEMS) is characterized clinically by fluctuating muscular weakness; presentation with ocular symptoms is unusual. A 60-year-old man had developed diplopia and ptosis 2 years previously. The findings of a neurologic examination were normal except for bilateral ptosis and ophthalmoplegia. The amplitude of compound muscle action potentials recorded on the abductor digiti minimi increased (by more than 500%) during 50-Hz stimulation. This case demonstrates that LEMS should be included in the differential diagnosis of myasthenic symptom confined to the ocular muscles.

Seizures are a common presenting manifestation in patients in a nonketotic hyperglycemic(NKH) hyperosmolar state and the MR findings are typically hyperintense on T2 weighted (T2-W) and fluid attenuated inversion recovery (FLAIR) images. We recently experienced a case of the patient with partial seizure and nonketotic hyperglycemia who showed T2-W and FLAIR hypointensities with T1 weighted (T1-W) contrast enhancement.
