RESUMO
The objective of our prospective study was to assess the role of contact thermography in children with migraine. Contact thermograms were done in 54 children aged 4.2-16.5 years (median 10.5 years), who were seen for headache and on 10 age-matched controls, between July and December 1991. Thermograms were interpreted as definitely normal, equivocally normal, equivocally abnormal, and definitely abnormal by a radiologist who was blinded to clinical information. Forty-eight children had the test between headaches; of these, four out of 26 patients (15%) who had migraine without aura and 3 out of 14 children (21%) who had migraine with aura had definitely abnormal thermograms. Nine out of 10 normal controls had definitely normal thermograms. The sensitivity of contact thermography in the diagnosis of childhood migraine, when done between headaches, was low in our study.
