title: Retropulsion and vertigo in the Chiari malformation: case report.
abstract: We describe a rare case of a 30 year-old woman with intense vertiginous sensation, lack of body balance and a tendency to fall backwards, making it necessary for two people to sustain her. The magnetic resonance imaging of the craniocervical junction evidenced tonsilar herniation at the inferior level of C1, and during the operation performed in sitting position, we observed crowding of the cerebellar tonsils at the level of C3. After the osteo-dural-neural decompression, the symptomatology remitted on the same day of the operation.
