Cerebellar peduncles MRI

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. MCP: Middle cerebellar peduncles; CSF: Cerebrospinal fluid; MRI: Magnetic resonance imaging; MS: Multiple sclerosis

Inferior cerebellar peduncle Radiology Reference Article

1. The cerebellum is connected to the brainstem by three cerebellar peduncles: 1)the inferior cerebellar peduncle (restiformbody and juxtrarestiform body) 2)the middle cerebellar peduncle (rachium pontis), and 3) the superior peduncle (brachium conjunctivum) (1). patThe wall and lateral roof of the 4th ventricle are formed by the inner surface
2. Brain stem and cerebellar involvement including cerebellar peduncles is common in patients with MS and ADEM. Cerebellar symptoms and signs are commonly seen in 50-80% in MS patients. On MRI brainstem lesions in 68% and cerebellar lesions in 49%-88% were detected (20)
3. In MSA-C, high-signal- intensity lesions are observed in the pons and middle cerebellar peduncles on T2-weighted MR images. Cruciform hyperintensity in the pons is known as hot cross bun sign, which may reflect loss of myelinated transverse pontocerebellar fibers (Figure 3A, D). spinocerebellar ataxia type 3 (scA3
4. The superior cerebellar peduncle is a paired structure of white matter that connects the cerebellum to the midbrain. It consists mainly of efferent fibers, the cerebellothalamic tract that runs from a cerebellar hemisphere to the contralateral thalamus, and the cerebellorubral tract that runs from a cerebellar hemisphere to the red nucleus
5. The MRPI is a ratio that encompasses measurements of the MCP and superior cerebellar peduncle (SCP) widths, as well as the cross-sectional area of the midbrain and pons; MRPI = [(Pons area/Midbrain area) x (MCP width/SCP width)]

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.

1. Atrophy involved the cerebellum, pons, and middle cerebellar peduncles in all cases. On intermediate and T2-weighted magnetic resonance (MR) images, abnormal signal intensity was always observed in the transverse pontine fibers, middle cerebellar peduncles, and cerebellum, structures known from pathologic study to degenerate in OPCA
2. The purpose of this study was to investigate what diseases affect both middle cerebellar peduncles (MCPs) and to evaluate other MR features for differential diagnosis. Methods: MR findings of 27 patients (14 male and 13 female; age range, 4-77 years [mean, 48.5 years]) with bilateral MCP lesions were retrospectively studied
3. Magnetic resonance imaging (MRI) of the pediatric brain provides key information to categorize and classify cerebellar malformations. A neurodevelopmental deficit is highly associated with different types of PCMs. Severe GDD was associated with cerebellar and brain stem involvement
4. The MRI brain study (Figures 1 and 2) showed pathologic symmetric signal of wm of the middle cerebellar peduncles (MCPs), specifically localized medially, superiorly and laterally to the dentate nuclei, showing restricted Diffusion on specific sequences. The MCPs transverse diameter was reduced
5. Previously, WD of the middle cerebellar peduncles (MCPs) following pontine infarction has been rarely depicted on conventional magnetic resonance imaging (MRI) studies. The MCP is vulnerable to WD because it is the largest and the the main path for pontocerebellar tracts
6. Results. Of the 172 patients, 112 (65%) had middle cerebellar peduncle T2 lesions and 74 (43%) had superior cerebellar peduncle T2 lesions. T2 lesions in the middle and superior cerebellar peduncles were more common in clinically impaired patients than in unimpaired patients (P = .05 to <.0001).Most conventional magnetic resonance imaging metrics were more abnormal in impaired patients than in.
7. Orthogonal diffusion-weighted MRI measures distinguish region-specific degeneration in cerebellar ataxia subtypes. Ying SH, Landman BA, Chowdhury S, Sinofsky The cerebellar peduncles are excellent candidates for composite indicators of regional degeneration in posterior fossa structures, as the peduncles show histopathological changes in.

• There are few case reports of MRI abnormalities in the bilateral middle cerebellar peduncles in hypoglycemic encephalopathy.
