Prolonged Migraine Stuttering Aura: Structural, Functional, and Video Neuroimaging Study of an Atypical Migraine Aura. A Case Report.

Stuttering is a disorder in the rhythm of speech characterized by an involuntary repetition, prolongation, and cessation of sounds. Neurogenic acquired stuttering is a very rare disorder which could result from different conditions with the involvement of several brain locations.A 16-year-old male presented to our Hospital with headache associated with blurred vision followed by right-sided facial and upper limb tingling, clumsiness of right arm, and a complete inability to formulate language which evolved in the next minutes into an intense speech disorder characterized by persistent stuttering. Urgent brain magnetic resonance imaging showed a prominence of venous vasculature in left hemisphere in susceptibility weighted imaging sequence. A fluorodeoxyglucose-positron emission tomography revealed a bilateral occipital, temporal, and parietal hypometabolism. With the suspicion of migraine aura, analgesic treatment was administered. Symptoms progressively resolved inside 10 hours. Five months later he experienced a similar episode.This case report represents a diagnostic challenge and suggests the inclusion of stuttering within the neurological manifestations of higher cortical dysfunction that can be found as a result of migraine aura.
