Overview
CT scan may be helpful in the diagnosis of Arnold Chiari malformation. Findings on CT scan diagnostic of Arnold Chiari malformation depends on the subtype and include herniation of
cerebellar tonsils, vermis, and lower brain stem, underdeveloped cerebellum and crowded foramen magnum.
CT scan
CT scan may be helpful in the diagnosis of Arnold Chiari malformation. Findings on CT scan diagnostic of Arnold Chiari malformation depends on the subtype and include:[1][2]
- herniation of:
- Cerebellar tonsils and vermis
- lower brain stem
- Underdeveloped cerebellum
- Crowded foramen magnum
In the CT scan picture above:
- Red: tectal beaking
- Orange: corpus callosum dysgenesis
- Yellow: large mass intermedia
- Green: absence of fastigium
- Blue: low-lying tentorium/torcular
- Purple: vermian ectopia
