Vestibular Migraine with Visual Aura and Olfactory Hallucination in Children: Two Case Reports.

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.
