Background: This study aims to elucidate the effect of isolated cerebellar lesions sparing the brainstem on the auditory brainstem responses in children.
Methods: We enrolled 10 children (aged 1-16 years) with cerebellar lesions on neuroimaging but lacking clinical brainstem involvement signs and with normal brainstem volumes on magnetic resonance imaging.
Results: The interpeak latency of waves I and V was normal in 9 patients and was marginally prolonged in 1 patient. While amplitudes of waves I and III were normal, we noted a decreased amplitude of wave V and/or an increased I/V amplitude ratio in 6 patients; these included 5 of 8 patients with cerebellar hypoplasia/atrophy and 1 patient with acute cerebellar ataxia.
Conclusion: Our results support the hypothesis of an inhibitory input from the cerebellar fastigial nucleus on the inferior colliculus, which might be disinhibited because of Purkinje cells dysfunction due to cerebellar cortex lesions, especially within the cerebellar vermis.

Background And Objectives: Vanishing white matter disease (VWMD) is an autosomal recessive leukoencephalopathy caused by mutations in the EIF2B1-5 genes, typically rare in adulthood. We present a case of adult-onset VWMD with a novel EIF2B2 mutation.
Methods: We collected the patient's clinical data, cerebrospinal fluid (CSF) results, laboratory tests, imaging features, genetic analysis, and follow-up data over a 4-year period.

Background: Histiocytic sarcoma originates in various tissues, including the skin, lymph nodes, gastrointestinal tract, lungs, bone marrow, and central nervous system. Primary central nervous system histiocytic sarcoma (PCNSHS) is exceptionally rare, known for its aggressive behavior and poor prognosis. This report describes a case of PCNSHS in the cerebellum treated with surgery and radiotherapy.

Mitochondrial neurogastrointestinal encephalopathy (MNGIE) is a rare autosomal recessive disorder, manifesting with gastrointestinal dysmotility, cachexia, ptosis and peripheral neuropathy. Diffuse leukoencephalopathy in brain MRI is a hallmark of MNGIE. We report a case of a 21-year-old female with MNGIE, presenting with cachexia and chronic diarrhea.

Background: Cerebellar hemorrhage in neonates is increasingly being identified but is still underdiagnosed. While magnetic resonance imaging (MRI) is the optimal imaging modality for cerebellar hemorrhage evaluation, ultrasonography (US) is commonly used for screening. Characterizing the patterns and distribution of cerebellar hemorrhage lesions can help facilitate its detection by aiding to focus on prevailing type of cerebellar hemorrhage.
