A 52-year-old woman presented with a paresis of elevation of the right eye, equally severe in abduction and adduction (monocular elevation paresis). CT demonstrated a small, right-sided tumor of the mesodiencephalic junction. Monocular elevation paresis has been attributed to lesions of the contralateral pretectum, although proof has been lacking. Now, with documentation of an ipsilateral brainstem etiology, we can postulate a lesion affecting the upgaze efferents from the ipsilateral rostral interstitial nucleus of the medial longitudinal fasciculus.
一名52岁女性出现右眼上抬无力，外展和内收时程度相同（单眼上抬麻痹）。CT显示中脑间脑交界处右侧有一个小肿瘤。尽管缺乏证据，但单眼上抬麻痹一直被归因于对侧顶盖前区的病变。现在，有了同侧脑干病因的记录，我们可以推测病变影响了同侧内侧纵束嘴侧间质核的上视传出纤维。
