Objective We aim to report 4 patients with brief pain paroxysms whose clinical features remind of typical epicrania fugax (EF), except for the direction along a transverse trajectory. Background EF has been defined as a brief paroxysmal head pain, with stabbing quality, describing a linear or zig‐zag trajectory across the surface of one hemicranium. Methods We considered all patients attending the headache outpatient office at 3 tertiary hospitals from March 2008 to December 2015. We identified a total of 4 cases with dynamic pain paroxysms moving in coronal direction. Results The mean age at onset was 49 years (range 34–75). All the patients suffered a dynamic pain from parietal or temporal areas to the contralateral ones, crossing the midline in a linear or zig zag trajectory, the entire sequence lasting 2–3 seconds. No triggers were identified. One patient noticed mild interictal tenderness at the stemming point. The frequency of the attacks varied from 2 per week to 1 every 2 months. No underlying disorders were identified by physical and neurological exams and neuroimaging and laboratory tests. Conclusions Our patients presented with a paroxysmal head pain that might correspond to a transverse variant of EF. These observations may not only expand the EF phenotype but also reinforce the distinction between EF and pericranial neuralgias.
