    IntroductionHeadaches are a frequent cause of children's visits to different health care services but the epidemiological profile varies widely according to whether the sample is taken from among visits to hospital clinics, neuropaediatric units or emergency services.AimsThe aim of this study was to analyse the aetiologies of the cases of headache attended in a paediatric emergency service.Patients And MethodsWe conducted a retrospective analysis of patient records with headache as the main reason for visiting over a six month period at the Paediatric Emergency Department at the Centro Hospitalario Pereira Rossell. Aetiologies were classified according to International Headache Society (IHS) criteria and the information was completed by telephone if the medical records contained insufficient data.ResultsThe records of 185 children were studied, which represented 0.58% of the total number of visits. The most common aetiologies were non-cranial infections (43.1%), migraines (14.6%), tension-type headaches (9.2%), traumatic injury (8.1%) and sinusitis (5.4%). Serious causes constituted 4.9% of the total, with a predominance of tumours and infections of the central nervous system. The low percentage of viral meningitis in our series (1%) leads us to suspect an underdiagnosis of this disorder, given the scant number of cases in which the cerebrospinal fluid was examined.ConclusionsOur study confirmed the existence of a wide and varied range of aetiologies causing headaches, with a clear predominance of extracranial disorders and a low percentage of serious intracranial causes. Non-classifiable headaches made up 10.8% of the sample. Brain imaging studies were performed in 9.7% of cases, which is a considerably lower percentage than that of other series and demonstrates a rational use of this resource.
