A congenital defect affecting the hindbrain, which includes the cerebellum, pons, and medulla oblongata. This condition disrupts the normal development of these brain regions, leading to various neurological impairments.
Types of Rhombencephalon Malformation
- Dandy-Walker Syndrome: Characterized by an enlarged fourth ventricle, cyst formation near the base of the skull, and absence of part of the cerebellum.
- Chiari Malformation: Brain tissue extends into the spinal canal, often leading to headaches and other symptoms.
- Joubert Syndrome: Molar tooth sign on MRI with developmental delays, abnormal breathing patterns, and lack of muscle control.
- Pontocerebellar Hypoplasia: Severe developmental issues and brain structure abnormalities, typically detected at birth.
- Rhombencephalosynapsis: Fusion of the cerebellar hemispheres causing balance and coordination problems.
Causes of Rhombencephalon Malformation
