Hemicrania continua: a report of ten new cases.
Hemicrania continua (HC) is an uncommon primary headache first described as a syndrome in 1984. Being quite unusual, its clinical characterization still demands better description. The aim of this study is to present the main clinical characteristics of 10 patients with the diagnosis of HC seen in a tertiary center, critically discussing their main features. All subjects had strictly unilateral headache without side shift and absolute response to indomethacin. Seven patients (70%) presented autonomic features during pain exacerbations. Four (40%) had migrainous symptoms during the exacerbations and one presented partial relief with dihydroergotamine. One patient had pain excruciatingly severe during the exacerbations. Although the cardinal features of HC - continuous, unilateral, indomethacin responsive, remain strongly reliable, a refinement on the clinical characterization is needful and desired.
