Abstract
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.
