Overview
Brain CT scan may be helpful in the diagnosis of Friedreich's ataxia. Findings on CT scan suggestive of Friedreich's ataxia include: 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 the Fourth ventricle, brainstem ratio and cerebellopontine angle cistern and increased Evans' index.
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
- Increased Evans' index
- Atrophy of transverse diameter and surface area of the:
