MRA showed right P2 (arrow head) and left SCA (superior cerebellar
artery) occlusion (c).
The HIAs were measured twice, at the level of the cerebral peduncle (CP) and the level of the superior cerebellar
The red nucleus and the ipsilateral inferior olivary nucleus are connected via the central tegmental tract, and the dentate nucleus connects to the contralateral red nucleus through the superior cerebellar

artery infarction: a case study.
Radiologically, posterior fossa and brain stem anomalies are seen such as cerebellar vermian dysgenesis, expanded 4th ventricle, and thickened strained superior cerebellar
peduncle.2 Patients with JS may have varying clinical and radiological views.
Rhombencephalosynapsis (RS) is a rare congenital posterior fossa malformation characterised by hypogenesis or agenesis of the vermis, dorsal fusion of cerebellar hemispheres, and fusion of the dentate nuclei and superior cerebellar
3), a diagnosis of Joubert syndrome and related disorders (2) was made by the pathognomic finding of a 'molar tooth' sign at the ponto-mesencephalic junction, representing vermian aplasia and stretched superior cerebellar
peduncles with a deep interpeduncular fossa.
Basilar artery branches include the posterior cerebral, posterior choroidal artery, anterior inferior cerebellar and superior cerebellar
arteries.[10,12] The posterior cerebral artery supplies blood to the occipital lobes, medial and inferior surfaces of the temporal lobe, midbrain and third and lateral ventricles. When the posterior cerebral artery is occluded, the clinical symptoms include contralateral hemiplegia, sensory loss and ipsilateral visual field deficits.[6,23] The weakness seen with occlusion of the posterior cerebral artery is usually greater in the face and upper extremities.
The appearance of mesencephalon and superior cerebellar
peduncles has been described as molar tooth sign.
However atrophy of mamillary bodies, superior cerebellar
vermis and cortex may be permanent.
Magnetic resonance imaging and diffusion tensor imaging examinations have shown that functional interruptions of white matter bundles involving the efferent axons in the superior cerebellar
pedincules are an important pathophysiological component of cerebellar mutism (23).
He observed a severe decrease in Purkinje cell density with increasing age in superior cerebellar
vermis but not in the inferior cerebellar vermis.
(37) have demonstrated that superior cerebellar
peduncle atrophy is correlated to onset age, disease duration, and weight of clinical findings.
Clinical diagnosis and imaging parameters (Patterns of Regional Atrophy, Signal Changes or Microstructural Changes in T2 and Flair in Basal Ganglia, Pons, Midbrain, Middle and Superior Cerebellar
Peduncles and Cerebral Subcortical White Matter) are studied.
The Saltzman type I PTA joins the basilar artery at the level between superior cerebellar
artery (SCA) and anterior inferior cerebellar artery (AICA).
