Akinetopsia is a rare neurological syndrome characterized by an impaired perception of movement, often resulting from brain damage due to ischemia, epilepsy, or medication. It is also known as visual motion blindness, and patients with this condition are unable to perceive motion normally even with perfect visual acuity. This report aims to present a case of a patient in their late 40 s who developed akinetopsia and also an impairment in movement perception of objects without emitting sounds, after experiencing a late relapse of breast cancer with the occurrence of multiple brain metastases. The patient also experienced visual hallucinations, night terrors, and difficulty forming anterograde memory. Neuroimaging with MRI revealed severe brain damage, especially in the middle temporal area of the visual cortex. Akinetopsia is a rare phenomenon, and this is the first known case of its association with brain metastases.
动觉缺失是一种罕见的神经综合征，其特征是运动知觉受损，通常由缺血、癫痫或药物引起的脑损伤引起。它也被称为视觉运动盲，患有这种疾病的患者即使视力正常也无法正常感知运动。本报告旨在介绍一例 40 多岁的患者，该患者在患有乳腺癌并发生多处脑转移后出现迟发性复发，出现动觉缺失和对无声物体运动知觉的损害。该患者还经历了幻视、夜惊和形成顺行性记忆困难。MRI 神经影像学显示严重的脑损伤，特别是在视觉皮质的中颞区。动觉缺失是一种罕见的现象，这是已知的首例与脑转移瘤相关的病例。
