다리뇌 경색의 단독증상으로 발생한 핵간 눈근육 마비 1예 = A Case of Internuclear Ophthalmoplegia as an Isolated Symptom of Pontine Infarction

다국어 초록 (Multilingual Abstract)

Internuclear ophthalmoplegia (INO) is caused by a lesion involving the medial longitudinal fasciculus (MLF) that interconnects the ocular motor nuclei. A 65-year-old woman with diabetes for twenty years developed diplopia, nausea, and vomiting one day before the presentation to the emergency room. Examination revealed adduction impairment of the right eye, combined with dissociated abducting nystagmus in the left eye. Other findings of the neuro-logical examination were normal. T2-weighted brain magnetic resonance imaging showed a hyperintensity lesion in right medial pons where the MLF locates. INO may be an isolated manifestation of pontine infarction.
