There are six cerebellar peduncles in total, three on each side: Superior cerebellar peduncle is a paired structure of white matter that connects the cerebellum to the mid-brain.; Middle cerebellar peduncles connect the cerebellum to the pons and are composed entirely of centripetal fibers
  6. The cerebral peduncles are the two stalks that attach the cerebrum to the brainstem. They are structures at the front of the midbrain which arise from the ventral pons and contain the large ascending (sensory) and descending (motor) nerve tracts that run to and from the cerebrum from the pons. Mainly, the three common areas that give rise to the cerebral peduncles are the cerebral cortex, the.

6-year old boy with joubert syndrome. Axial non-contrast CT images of the brain showing dilated batwing-shaped fourth ventricle (A), hypoplastic vermis (A, B) in addition to thickened and elongated superior cerebellar peduncles with deep interpeduncular fossa (A, B) giving molar-tooth appearance In the context of a prior pontine infarct the main differential consideration is that of bilateral AICA infarction and Wallerian degeneration . Wallerian degeneration is favored given the very symmetric nature of the abnormality and the presence of the pontine infarct. This is a recognized pattern 1-3,5 . Acknowledgement: Prof Stephen Stuckey The CT criteria for the evaluation of cerebellar atrophy are similar to those that have been identified by PEG and include: (1) enlarge­ ment of the cerebellar sulci, (2) enlargement of the cerebellopontine cisterns, (3) enlargement of the superior cerebellar cistern, and (4) enlargement of the fourth ventricle [5].

Cerebellar peduncles. The cerebellum attaches to the posterior aspect of the brainstem by 3 large tracts, the superior, middle and inferior cerebellar peduncles. Do not confuse these with the cerebral peduncle. Superior cerebellar peduncle (brachium conjunctivum) contains efferent fibres from the cerebellum to other centres Erdheim-Chester disease (ECD), a rare disorder of monocyte/macrophage lineage, has been related to cerebellar dysfunction. To increase the awareness of this rare, protean disease, an unusual, myasthenia-like onset of ECD is reported. A 42-year-old man presented with a 6-year history of mild evening fatigability in his four limbs followed by motor and cognitive symptoms associated with.

The cerebellum is connected to the brainstem by three pairs of cerebellar peduncles: the superior peduncle with the midbrain, the middle peduncle with the pons, and the inferior peduncle with the medulla oblongata. Afferent and efferent connections that run between the cerebellum, brainstem and spinal cord, travel through the cerebellar peduncles The brain is conceded to be the master organ of the body, the regulator of life, the source of human progress. The brain is a muscle of busy hills, the struggle of unthought things with things eternally thought. The brain appears to possess a special area which we might call poetic memory and which records everything that charms or touches us. Primary central nervous system lymphoma (PCNSL) is rare. And the symptoms of PCNSL are atypical, it is extremely easy to be misdiagnosed as other diseases. However, early treatment is crucial which is requesting early diagnosis. We report a case of a 47-year-old man who was initially diagnosed as ne The cerebellar peduncles are part of a complex motor network (Schmahmann and Pandya 1997) and, given that we observe motor abilities mediating higher order cognitive measures in PT individuals, it is not surprising to observe neuro-correlates of these measures in traditional motor networks
