The cerebellum abnormalities may be hypoplastic, dysplastic, or hypoplastic. It is very rare that the cerebellar hemisphere is affected unilaterally in the posterior fossa abnormalities. The reason for this effect is mostly sequela. This pathology presents with neuromotor developmental abnormalities. In this presentation, isolated left cerebellar hypoplasia is described radiologically in a 21-month-old male patient with neuromotor development defects. Dysplastic appearance was noticeable in the observable part of the left cerebellar hemisphere and folia. The cerebellar vermis could not be shaped. The right cerebellar hemisphere, other posterior fossa formations, and supratentorial area were natural. In patients with neuromuscular abnormalities, the posterior fossa is applied with care. It should be remembered that cerebellar hypoplasia and dysplasia can be unilateral.
