A 21-year-old man experienced sudden and intense rotational vertigo. A moment later, he was amazed to see the whole visual world rotate clockwise progressively by about 160 degrees. On the following day, the visual tilt was only 30 degrees, and it soon receded completely, while headache appeared. CT scan, magnetic resonance imaging, vertebral arteriography, and cerebrospinal fluid analysis were normal, and the aetiology could not be ascertained. Illusions of visual tilt are an unusual consequence of disorders affecting the vestibular system. The locus of the impairment is usually in the brainstem, particularly in association with Wallenberg's syndrome. However, the peripheral vestibular pathways or the vestibular projections into the cerebral cortex may occasionally be involved. In the latter case, the visual tilt is part of a vestibular epileptic seizure.
一名21岁男性经历了突发且强烈的旋转性眩晕。片刻之后，他惊讶地发现整个视觉世界顺时针逐渐旋转了约160度。次日，视觉倾斜仅为30度，且很快完全消退，同时出现了头痛。CT扫描、磁共振成像、椎动脉造影和脑脊液分析均正常，病因无法确定。视觉倾斜幻觉是影响前庭系统疾病的一种不寻常后果。损伤部位通常在脑干，特别是与延髓背外侧综合征相关。然而，外周前庭通路或前庭向大脑皮层的投射偶尔也可能受累。在后一种情况下，视觉倾斜是前庭癫痫发作的一部分。
