Learning objectives: Elucidate a diagnose of cerebellar hemiatrophy that is a nonspecific finding in neuroimaging studies of children with multitude of different findings.

Background: Atrophy, in general terms, implies (irreversible) loss of tissue1,2. Mitochondrial disease was the most common cause of cerebellar atrophy, according to Al-Maawali3. It´s important to notice that vast majority of hereditary cerebellar atrophy does not lead to significant brainstem atrophy, even in a[...]

Findings and procedure details: Neuroimaging like computed tomography (CT) and magnetic resonance imaging (MRI) play key diagnostic role in neurology, especially paediatric2 – the axial section is the best section to see cerebellar atrophy of the hemispheres1. The presence of cerebellar atrophy on neuroimaging can facilitate selec[...]

Conclusion: Although uncommon, cerebellar hemiatrophy should be investigated for additional findings and for the investigation of its possible causes.
