IntroductionIntermittent fever has been occasionally related to migraine, either as a migraine equivalent or as a migraine accompaniment. We present a case of recurrent increase in body temperature consistently associated with migraine headaches.MethodsA 15-year-old girl reported a 3-year lasting history of migraine without aura, with a feeling of warmth occurring in each episode. Ancillary tests did not show any evidence of secondary headaches or any systemic disease. A 2-month headache diary was obtained, with daily records of headache intensity (0, no headache; 1, mild pain; 2, moderate pain; 3, severe pain) and simultaneous measurements of axillary temperature. Both parameters were registered in the evening, at 6:00 pm every day. The distribution of headache intensity and body temperature as well as the relationship between both variables over time were analyzed with nonparametric tests.ResultsThe number of days without pain was 28 (45.2%); a mild headache was present on 13 days (21%), a moderate headache on 15 days (24.2%), and a severe headache on 6 days (9.7%). Headache days were associated with higher body temperature than headache-free days (median values: 37.3°C vs 36.6°C; Mann-Whitney U-test, P < 0.001). Moreover, a positive correlation was found between headache intensity and body temperature (Spearman's rho coefficient: 0.83, P < 0.001).ConclusionsRecurrent increase in body temperature may be another manifestation of the complex clinical spectrum of migraine. This symptom is probably related to hypothalamic involvement.Wiley Periodicals, Inc.
