Benign paroxysmal positional vertigo (BPPV) in a child is known to be very rare. There are very few papers about nystagmus during BPPV episode in a child. A nine-year-old girl who complained of severe positional vertigo was admitted to our hospital. There were no abnormal findings on physical examination and brain magnetic resonance imaging (MRI). When she was placed in a supine position, we could record characteristic positional nystagmus using video-oculography. On subsequent off-line analysis of that nystagmus recording, we diagnosed her as having BPPV in the horizontal semicircular canal. About 2 weeks earlier, she had sustained a bruise on her head and we considered that this bruise may have caused her BPPV attack. Positional vertigo decreased very quickly and she hospitalized for only 2 days for observation without any special treatment.
Key words :BPPV, children, horizontal semicircular canal type
