Background: Approximately 3.9% children with migraine have olfactory hallucination which was defined as a perception of a smell without the substantial existence of any physical odor.
Case: We described the first two cases of children with vestibular migraine, presenting visual aura and olfactory hallucination. We reported two children with vertigo, visual aura, and olfactory hallucination before the headache who were responsive to topiramate.
Conclusion: The clinical description of olfactory hallucination presented some characteristics of migraine aura. Olfactory hallucinations could be inserted as a migraine aura in International Classification of Headache Disorders.
