A man aged 26 years had been subject to frequent transient episodes of left homonymous hemianopia, initially accompanied by visual hallucinations and left miosis, since the age of 8 years. These partial seizures recurred 3 to 30 times each month in spite of treatment with anticonvulsant medication. The causative lesion, which had escaped detection by cerebral angiography and repeated computed tomographic scanning, was shown by magnetic resonance imaging to be a small cavernous hemangioma in the right occipital lobe. This was treated by a course of fine-beam radiotherapy directed to the lesion. After treatment the partial attacks ceased, although one nocturnal clonic seizure occurred 12 months after radiotherapy and 6 weeks after stopping all anticonvulsant medication.
一名26岁男性自8岁起就频繁出现短暂性左侧同向性偏盲发作，最初伴有视幻觉和左侧瞳孔缩小。尽管使用抗惊厥药物治疗，这些部分性发作每月仍复发3至30次。脑血管造影和多次计算机断层扫描均未发现致病病变，而磁共振成像显示右侧枕叶有一个小海绵状血管瘤。针对该病变进行了一个疗程的细束放射治疗。治疗后部分性发作停止，尽管放疗后12个月且停用所有抗惊厥药物6周后出现了一次夜间阵挛性发作。
