Presentation
Developmental delay and hypotonia
Patient Data
The left cerebellar hemisphere shows reduced volume, disorganized & vertically oriented cerebellar folia,multiple enlarged vertical clefts, bumby gray-white matter interface and lack of normal arborization of its white matter.
Posterior fossa left retro-cerebellar arachnoid cyst shows a thin hypointense wall.
Dysgenesis of the corpus callosum with widely separated parallel lateral ventricles showing mild colpocephaly.
Right frontal cortical dysplasia and subependymal grey matter heterotopia.
Case Discussion
This case illustrates how often multiple abnormalities coexist:
- cerebellar dysplasia
- arachnoid cyst
- grey matter heterotopia
- cortical dysplasia
- callosal dysgenesis
