-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.KEY WORDS: hemicrania continua, clinical characterization, classification. Hemicrania continua: relato de dez novos casosRESUMO -Hemicrania continua (HC) é uma cefaléia primária relativamente incomum primeiramente descrita enquanto sindrome em 1984. Por ser relativamente rara, sua apresentação clínica ainda carece de melhor descrição. O objetivo do presente estudo é apresentar e criticamente discutir as principais características clínicas de 10 pacientes com HC consecutivamente vistos em um centro de atendimento especializado. Todos os pacientes apresentavam cefaléia estritamente unilateral, sem alternância de lado e com absoluta resposta a indometacina. Sete pacientes (70%) apresentavam sinais autonômicos durante a exacerbação da dor. Quatro (40%) apresentavam sintomas migranosos durante as exacerbações e um apresentava alívio parcial com diidroergotamina. Um paciente apresentava exacerbações excruciantemente severas. Embora as principais características da HC -dor continua, unilateral, responsiva à indometacina -permaneçam extremamente associados à sindrome, um refinamento na caracterização clínica é necessário. PALAVRAS-CHAVE: hemicrania continua, características clínicas, classificação.

“…Several aspects concerning its clinical characterization and consequently classification remain controversial 8 . According Spierings 2 and Pareja et al 4 , HC is a unilateral headache syndrome with fixed lateralization, that is, the headaches always occur in the same side of the head.…”

“…According to some investigators, this headache, nevertheless, seemed to 'meet the phenotype' (of HC) (2). It should be emphasized that the original, genuine HC-picture persists, as previously perceived, unassailed/unstained, through this, actually rather low-energy, upheaval.…”

“…Neurological examination was pertinent for corrected visual acuity of 20/50 in both eyes and bilateral papilledema. 1 The motor, cerebellar, gait, and sensory examinations were unremarkable, but deep tendon reflexes were hyperactive with bilateral extensor plantar responses. Brain MRI showed thick, enhancing, dural-based sarcoid lesions in the falcial, parafalcial, anterior, and central basal regions (figure).…”
