Epicrania fugax (EF) has been recently described as a paroxysmal head pain starting in a focal cranial area of the posterior scalp and rapidly spreading forward to the ipsilateral eye or nose along a linear or zigzag trajectory. Here we report two patients presenting with the same clinical features, except for the starting site and the direction of the pain. Unilateral pain paroxysms occurred on either side of the head, with a quick backward radiation along a linear trajectory. The pain always stemmed from a particular point located at the fronto-parietal region, and reached the parieto-occipital region in several seconds. The symptoms did not fit any of the acknowledged headaches and neuralgias, and might correspond to a reverse variant of EF.
短暂性头部单侧疼痛（EF）最近被描述为一种阵发性头痛，起始于枕后头皮的局部区域，并迅速沿线性或锯齿状轨迹向前扩散至同侧眼睛或鼻子。在这里，我们报告了两名具有相同临床特征的患者，除了起始部位和疼痛方向。单侧疼痛发作发生在头部的任意一侧，疼痛呈线性轨迹迅速向后辐射。疼痛总是源自位于额顶区域的特定点，并在数秒内到达顶枕区域。这些症状不符合任何已知的头痛和神经痛类型，可能对应于 EF 的反向变异。
