Chiari I malformation

Case contributed by Assoc Prof Frank Gaillard

Low lying cerebellar tonsils which extend below the margins of the foramen magnum by ~10mm and tightly embrace the medulla (best seen on axial imaging). There is no evidence of a syrinx or hydrocephalus. Features are consistent with an incidental Chiari 1 malformation.
