Background: Gangliogliomas (GGs) are rare intra-axial tumors. Cerebellar seizures caused by GGs have been described only rarely. Pigmented neural cell tumors are well described in the literature but are infrequent, especially when presenting as primary neuroepithelial tumors. Only 5 cases of pigmented GG have been reported previously, including 4 in the pediatric population.
Case Description: A 17-year-old female presented to us with cerebellar seizures, which resolved after tumor excision. Histopathological examination revealed a pigmented GG.
Conclusions: We present the sixth documented case of a pigmented ganglioglioma, the first such case reported in cerebellar location, associated with a rare presentation of cerebellar seizures.

Rare inherited diseases caused by mutations in the copper transporters (CTR1) or induce copper deficiency in the brain, causing seizures and neurodegeneration in infancy through poorly understood mechanisms. Here, we used multiple model systems to characterize the molecular mechanisms by which neuronal cells respond to copper deficiency. Targeted deletion of CTR1 in neuroblastoma cells produced copper deficiency that produced a metabolic shift favoring glycolysis over oxidative phosphorylation.

Postseizure brain changes on imaging are well-known facts. Many times, oedematous brain changes can mimic ischaemic stroke. Crossed cerebellar diaschisis refers to a depression in metabolism, affecting the cerebellar hemisphere due to contralateral supratentorial abnormalities.

is an intracellular protozoan parasite that infects a wide range of vertebrates, including humans. Although cats are the only definitive host, any warm-blooded animal can act as a paratenic host. Throughout the years, this apicomplexan parasite has been studied due to its wide prevalence, zoonotic potential, and host behavioral alterations.

Erdheim-Chester Disease is a rare systemic xanthogranulomatous infiltrating disease, characterized by lipid-laden histiocytes accumulating in various organs and almost always in bones. Etiology of the disease is still unknown. It may involve various organs and systems, such as musculoskeletal, cardiac, pulmonary, renal, gastrointestinal and central nervous system (CNS) as well as the skin.

We report a case of a Chinese girl who presented with multiple seizure types of epilepsy, followed by motor and intellectual regression, vision impairment, and cerebral and cerebellar atrophy. She carries an unreported compound heterozygous variant of the ASAH1 gene and is diagnosed with spinal muscular atrophy associated with progressive myoclonic epilepsy (SMA-PME), a disorder in which ceramide accumulation in lysosomes due to a decrease in acid ceramidase activity. This case suggests attention to this rare class of deceases involving both the central and peripheral nervous systems.
