Overview
CT scan
Brain CT scan may be helpful in the diagnosis of Friedreich's ataxia. Findings on CT scan suggestive of Friedreich's ataxia include:[1]
- Moderate cerebellar atrophy and an increase in the surface area of the fourth ventricle in two-thirds of the patients
- Atrophy of the number and width of cerebellar sulci
- Olivopontocerebellar atrophy with or without supratentorial atrophy
- Atrophy of transverse diameter and surface area of the:
- Fourth ventricle
- Brainstem ratio
- Cerebellopontine angle cistern
- Evans' index
