c) Left internal carotid injection in late arterial phase showing a PTA that supplies the anterior inferior cerebellar arteries (AICA) and inferior vermian
(arrow) and hemispheric (arrowhead) branches of posterior inferior cerebellar arteries (PICA).
As we mentioned above, lexical deficiencies have been shown in vermian
The constellation of episodic hyperpnoea, developmental delay and cerebellar vermian
dysgenesis with ataxia was initially described by Joubert et al in 1969.
Radiologically, posterior fossa and brain stem anomalies are seen such as cerebellar vermian
dysgenesis, expanded 4th ventricle, and thickened strained superior cerebellar peduncle.
Marie Joubert first described this syndrome in 1968 as a rare autosomal recessive disorder characterised by the neuroradiological hallmark of the molar tooth sign caused by cerebellar vermian
These results suggested that the specialized abilities of balance and coordination in skaters are associated with a certain amount of flexibility in the structure of the right hemisphere of the cerebellum and vermian

The so-called sag model postulates that haemorrhage results from altered cerebrospinal fluid hydrodynamics, causing caudal sagging of the cerebellum with stretching of cerebellar vermian
Sonographic detection of inferior vermian
agenesis in Dandy-Walker malformations: prognostic implications.
The various posterior fossa malformations detected were Dandy Walker malformation (DWM, 1 case), Dandy Walker variant (DWV, 2 cases), mega cisterna magna (MCM, 8 cases), arachnoid cysts (5 cases), Chiari 1 malformation (5 cases), Chairi 2 malformation (2 cases), Joubert malformation (1 case), lipoma (2 cases), vermian
and/or cerebellar hypoplasia without posterior fossa cysts (4 cases).
The tumor was removed almost completely by vermian
incision using surgery microscope (Picture 2).
