There are three subtypes which affect multiple organs to varying degrees, but the fundamental abnormalities involve the cerebellum [1] which controls muscle coordination. A case report and literature review”.

Beales; Nicholas Katsanis September Prenatal diagnosis of congenital anomalies. The adjacent third and fourth ventricles are often affected, which awlker alter the flow of cerebrospinal fluidincrease intracranial pressureand lead to multiple other brain function problems. A special tube shunt to reduce intracranial pressure may be placed inside the skull to control swelling. Retrieved from ” https: Specialised Social Services Eurordis directory.

The pathogenesis is incertain; it is generally agreed that it is originated from a developmental disorder brought about by the non-opening of the foramina of Luschka and Magendie.

The abnormally high position of dandt transverse sinuses, as seen in the X-ray of the skull or in the sinugram, is considered a pathognomonical sign.
