ABSTRACT
Introduction Epicrania fugax (EF) is a primary headache whose main feature is the dynamic character of the pain. EF pain typically moves across different dermatomes in a linear or zigzag trajectory. Recently, a facial variant of EF has been described, with the pain starting in the lower face and radiating upwards. Aim We report eight patients with an EF-type of pain of facial location and either upward or downward radiation. Methods For each patient, we recorded relevant demographic and clinical data. Magnetic resonance imaging (MRI) with fast imaging employing steady state acquisition (FIESTA) was obtained in all cases for the assessment of neurovascular compression of the trigeminal nerve. Results There were seven women and one man, and the mean age was 76.1 years (standard deviation, 11.3). Six patients had a paroxysmal pain starting at the lower face and moving upwards, while two patients had downward radiation. The pain always followed a fixed linear trajectory across different dermatomes. All cases had triggers, and pain intensity was consistently severe. Half of the patients had accompanying autonomic features. Neurovascular compression with imprinting over the trigeminal root on the symptomatic side was identified in three patients. All cases responded to antiepileptic drugs, and three had spontaneous remissions. Conclusions This series reinforces the facial variant of EF and extends the phenotype with cases of downward radiation. It also contributes to enriching the differential diagnosis of facial pain. Neurovascular compression of the trigeminal nerve may be found in some cases, although a possible pathogenic link needs further research.
