متن کاملOcular Neuromyotonia and Myasthenia Gravis.
To the Editors: Myasthenia gravis presents with only ocular symptoms (diplopia, ptosis, and extraocular movement limitation) in approximately 20% of patients.1,2 Ocular myasthenia gravis is to be suspected in patients with intermittent diplopia with ophthalmoplegia that does not correspond to a single ocular motor nerve paresis. However, diplopia in only eccentric sustained gaze in myasthenia g...

patient was resting, causing contraction of all the muscles innervated by the left seventh cranial nerve. MR angiography revealed a neurovascular compression of the left facial nerve by the anterior inferior cerebellar artery (AICA) (figures 1 and 2). The patient was taken to surgery and a microvascular decompression through a retrosigmoid approach was performed. Facial nerve function monitorin...
