[Imaging of the pediatric cerebellum].
After a brief overview of embryology, histogenesis, anatomy, as well as terminology, the authors will review the main acquired (neoplastic and non-neoplastic) and congenital (malformative and non-malformative) cerebellar pathologies through a pictorial essay. Even though there is some overlap, malformations are classified into agenesis, hypoplasia, and dysplasia, either cystic or non-cystic. Their embryological origin will be discussed. The main known syndromes associated with vermian agenesis will be reviewed. Non-neoplastic acquired cerebellar lesions, including atrophy and isolated signal anomalies, will be briefly reviewed. A classification of the main cerebellar malformations will be proposed.
