Migraine and nosebleed in children case series and literature review

The presence of nose bleeding during a migraine attack as a single occurrence is so far rarely reported. Therefore, we have decided to report such occurrences we have noticed to further improve and build upon possible existing knowledge of such incidences. Method: 728 children with an average age of 11.5 years, suffering from migraine were examined for nose bleeding. All structural, trauma, coagulation and medical causes were excluded. A computer-based literature search was also conducted to identity other cases of such sort. Results: Eight cases (1.1%) of nose bleeding during attacks of migraine with no other known causes were identified. An additional 3 cases were identified in literature, though the presenting age was 25 years or above. Conclusion: In our case series, nose bleeding exclusively occurred during the attacks of headaches, although it was not considerably related to aura, frequency, location or intensity of migraine attacks. The presence of nose bleeding associated with migraine is an uncommon phenomenon and its mechanism is still unknown. (C) 2014 European Paediatric Neurology Society. Published by Elsevier Ltd.
