Migraine is a common clinical disorder, quite disabling and affecting the quality of life in majority of patients. The visual aura is the commonest among all types of aura. Various types of migraine aura described in the literature are photopsia, fortification spectra, scotoma, visual distortion, haemianopia and metamorphsia. The epileptic visual aura differs from aura associated with migraine in certain features: short lasting for 2-3 minutes, occurring in clusters, multicoloured and circular in shape. The ictal manifestations of occipital lobe lesions can mimic episodes of migraine with visual aura according to some reports. In this case report, we intended to highlight aggravation and increased frequency of headache attacks and changed pattern of aura induced by occipital lobe cysticercus granuloma in a patient diagnosed of migraine with aura. The importance of neuroimaging of brain in state of unexpected increased frequency of headache episodes has been emphasised.
偏头痛是一种常见的临床疾病，极具致残性，影响大多数患者的生活质量。视觉先兆是所有类型先兆中最常见的。文献中描述的各种偏头痛先兆包括闪光幻觉、堡垒样光谱、暗点、视觉变形、偏盲和视物变形。癫痫性视觉先兆在某些特征上与偏头痛相关先兆不同：持续时间短，为2 - 3分钟，成簇出现，形状为多色圆形。根据一些报道，枕叶病变的发作期表现可模仿伴有视觉先兆的偏头痛发作。在本病例报告中，我们旨在强调一名诊断为伴有先兆偏头痛的患者，枕叶囊尾蚴肉芽肿导致头痛发作加重、频率增加以及先兆模式改变。已强调了在头痛发作频率意外增加的情况下进行脑部神经影像学检查的重要性。
