The principal MRI findings of Joubert syndrome are deep interpeduncular fossa together with a narrowing of the isthmus, thickening of the superior cerebellar peduncle, fourth ventricle deformity together with hypolplasia of the vermis, fastigumun rostral shift and sagittal vermian cleft originating from the incomplete union of the two halves of the vermis.
The superior cerebellar artery (Table 2) supplies blood to the upper part of the cerebellum and the midbrain.[10,12] Brain attack of this vessel causes ipsilateral cerebellar ataxia, nausea, vomiting, slurred speech and contralateral loss of pain and thermal sensation.[4]

The imminent pathology in the MVD responsible for the problem has been compression by an artery usually a Superior Cerebellar Artery(SCA) or loop of Anterior Inferior Cerebellar artery(AICA), venous pathology implicated as a cause been reported in some series as high as 80-90% especially in the recurrent conditions and in the younger age group5-8.
There is severe hypogenesis of the cerebellar vermis, enlarged, horizontal superior cerebellar peduncles, a small mid brain in the anteroposterior direction, and a "batwing" configuration of the mid-superior fourth ventricle (Figures 1 and 2).
A correlative proton MR Spectroscopy (1H MRS) exam was performed on the abnormal area in the right superior cerebellar hemisphere using both short and long echo times (TE) of 144 and 35 ms, respectively (Figure 2).
The superficial temporal artery, occipital artery, and external carotid artery can be used to increase blood flow to superior cerebellar artery, posterior cerebral artery, posterior inferior cerebellar artery, or anterior inferior cerebellar artery [10].
(1) This appearance is a result of absence or hypoplasia of the cerebellar vermis, lack of normal dorsal decussation and consequent enlargement of the superior cerebellar peduncles which follow a more horizontal course as they extend perpendicularly to the brainstem between the midbrain and the cerebellum.
This inhibitory effect is absent in cerebellar patients when lesions involve dentate nuclei or the superior cerebellar peduncle [27].
