The inferior cerebellar peduncles are paired structures containing important white matter fiber tracts which connect the cerebellum to the medulla. Gross anatomy The inferior cerebellar peduncles are composed of a large restiform body and a small juxtarestiform body Cerebellar peduncles, two stalks or columns, connect the cerebellum to the brainstem. Cerebellum and Diagnostic Medical Imaging Different diagnostic tools for neuroimaging (brain imaging) allow doctors to observe and evaluate the parts, functions, and interactions of the brain regions, including the cerebellum (9) PCNSL was indicated by a significant and characteristic fist sign on contrast-enhanced MRI. Conclusions: Bilateral MCP lesions were most frequently observed in cerebrovascular diseases, followed by neurodegenerative diseases, inflammatory diseases, toxic encephalopathies, and lymphomas To set age-specific normal reference values for brainstem, cerebellar vermis, and peduncles measurements and characterize values' variations according to gender, age, and age by gender interaction. Methods: 565 normal brain magnetic resonance examinations with normal anatomy and signal intensity of the supra- and infratentorial structures were. Additional lesion found in the thoracic cord (not shown) and CSF led to the diagnosis of MS.

The middle cerebellar peduncle (MCP), also called the brachium pontis, is the largest afferent system of the cerebellum. It consists of pontocerebellar tract (PCT) fibers arising from the contralateral pontine nuclei (Perrini, Tiezzi, Castagna, & Vannozzi, 2013) Multiple system atrophy (MSA) is a sporadic progressive adult-onset neurodegenerative disorder associated with varying degrees of parkinsonism and autonomic, pyramidal, and cerebellar dysfunction. 1 Hyperintensity of the middle cerebellar peduncle (MCP) on T2-weighted images has been suggested to be more frequent in patients with MSA, 1,2 especially the cerebellar dominant type of multiple system atrophy (MSA-c). 3-6 It is reported to be a useful radiologic sign to differentiate between. Description. The cerebral peduncles (pedunculus cerebri; crus cerebri) are two cylindrical masses situated at the base of the brain, and largely hidden by the temporal lobes of the cerebrum, which must be drawn aside or removed in order to expose them.They emerge from the upper surface of the pons, one on either side of the middle line, and, diverging as they pass upward and forward, disappear.
Cerebellar ataxia was found in 20 patients (30%). The MRI study showed that the lesions responsible for ataxia in these patients were mainly found in the cerebel-lar peduncles, but cerebellar hemispheric lesions were detected in only four patients (6.4%). Conclusion—The low frequency (6.4%) of the cerebellar MRI lesions in these pa Objective: To use diffusion tensor MRI to quantify and compare degeneration of the pons and cerebellar peduncles in multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and Parkinson disease (PD) and to relate changes in diffusion measures to clinical features and localized atrophy. Methods: We used a region-of-interest approach to. . MRI-based cerebellar volume measurements were performed in all subjects using T1-weighted images acquired with a 1.5-T MRI scanner
Surgical resection of all or most of the tumor is possible in most cases unless it has spread to the 4th ventricle or cerebellar peduncle. Postoperative lumbar puncture to look for tumor cells and gadolinium-enhanced MRI to look for leptomeningeal involvement (for neuroaxial drop metastasis) should be performed Cerebellar peduncles connect the cerebellum to the brain stem. 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 Barry White1944 - 2003You're my everything. This knowledge can be incorporated into the microsurgical approach of cerebellum and cerebellar peduncles and can improve the topographical accuracy of cerebellar lesions in MRI studies and their interconnection with clinical findings, eg, hypertensive hemorrhages that involves usually dentate nucleus, posterior fossa tumors, multiple sclerosis, iron deposition disorders FASI was most commonly seen in the brainstem and basal ganglia in addition to the cerebellum. One patient had two basal ganglia FASI on the first scan but developed FASI in the middle cerebellar peduncle on the second MRI. The rest of the patients had cerebellar FASI on the first MRI
The fragile X premutation tremor/ataxia syndrome (FXTAS) is a recently described adult-onset neurodegenerative disorder, in which ataxia, tremor, cognitive decline, parkinsonism, neuropathy and autonomic dysfunction occur in various combinations. It is reported to display a characteristic MRI appearance, with increased T2 signal in the middle cerebellar peduncles and around the dentate nuclei The MRI study showed that the lesions responsible for ataxia in these patients were mainly found in the cerebellar peduncles, but cerebellar hemispheric lesions were detected in only four patients (6.4%). Conclusion - The low frequency (6.4%) of the cerebellar MRI lesions in these patients is in sharp contrast with the figures reported for. AICA supplies the anterior portion of the inferior cerebellum, the middle cerebellar peduncle, and the facial and vestibulocochlear nerves. The superior cerebellar artery supplies most of the cerebellar cortex, the cerebellar nuclei, and the superior cerebellar peduncles not rule out cerebellar infarction, either in the acute or in the subacute period. MRI, specifically diffusion-weighted imag-ing, may be required to make the diagnosis.12,13 Management Management of cerebellar infarction is similar to infarcts of other areas of the brain.

The decussation of the superior cerebellar peduncles can be seen centrally at this level with some reticular formation (noted throughout the brainstem) lying lateral. Between the central gray matter and the substantia nigra are four lemnisci. Moving anterior to posterior they are the medial, spinal, trigeminal, and lateral leminisci
Descriptions of WD of the cerebellar peduncles are rare, but when it occurs, WD usually involves the MCPs because they are the largest and the main path for the pontocerebellar tracts . Histologic and metabolic features can be correlated with specific findings on MRI Brain MRI in patient 2 at age 6 years showed small midbrain, pons, and middle cerebellar peduncles. Patient 3 had cerebellar hypoplasia, ataxia, seizures, optic atrophy, and retinitis pigmentosa. At age 26 years, she had moderately to severely impaired ID, a vocabulary of 4 to 5 words, and was nonambulatory He was diagnosed as having a pontine lacunar infarction. The contralateral cerebellar lesions were caused by involvement of the pontocerebellar fibers. On the 29th day from the onset, MRI showed the new abnormal high intensity lesions at the bilateral middle cerebellar peduncles on T2WI
Cerebellar peduncle Cerebellar peduncle is made of bundles of nerve fibers. The cerebellum is connected to other parts of the central nervous system by numerous efferent and afferent fibers that are grouped together on each side into three large bundles, or peduncles Among them, manifestations of facial, trigeminal, and abducens nerves were relatively common. Cerebellar ataxia was found in 20 patients (30%). The MRI study showed that the lesions responsible for ataxia in these patients were mainly found in the cerebellar peduncles, but cerebellar hemispheric lesions were detected in only four patients (6.4%) A voxel-wise analysis to diffusion tensor (DT) MRI tractography and T2 lesions metrics of the middle (M) and superior (S) cerebellar peduncles (CP) was applied to quantify their structural damage in multiple sclerosis (MS) patients and to assess its relationship with clinical disability

In addition to providing anchorage, these peduncles allow afferent and efferent nerve fibers and tracts to enter and leave the cerebellum. The blood supply to the cerebellum is via three main branches of the basilar artery. These are the superior cerebellar, anterior inferior cerebellar and posterior inferior cerebellar arteries The cerebellar peduncles are excellent candidates for composite indicators of regional degeneration in posterior fossa structures, Fingerprint Dive into the research topics of 'Orthogonal diffusion-weighted MRI measures distinguish region-specific degeneration in cerebellar ataxia subtypes'
MRI has significant value in diagnosing JS. In 1997, Maria described a typical MTS on an axial MRI of the disease characterized by an abnormally deep interpeduncular fossa, prominent, straight, and thickened superior cerebellar peduncles hypoplasia of the vermis. The axial MRI showed thick superior cerebellar peduncles, and the fourth ventricl peduncles and transverse pontine fibers in primary cerebellar atrophy group, while phenytoin users showed nearly the same fiber intactness as normal controls, suggesting phenytoin affects cerebellum directly with preserved interconnecting fibers.
