Migraine with Persistent Visual Aura: Response to Furosemide

Persistent migraine aura without infarction is a rare but well documented condition. According to the International Headache Society (HIS) criteria, this disturbance is defined by the persistence of a migraine aura for more than one week without radiographic evidence of infarction. Here we describe the case of an 11-year-old girl suffering from migraine without aura since the age of four. She experienced two episodes of persistent negative visual aura with no evidence of infarction. To the best of our knowledge, this is the first Brazilian case reported in the literature. Interestingly this patient demonstrated a clinical recovery following treatment with oral furosemide.
