Cerebellar GCMs in children are symptomatic lesions, which prompt immediate surgical treatment. These are rare lesions, which can radiologically and clinically mimic a tumor with bleed, having to be considered in the differential diagnosis of neoplastic lesions. Cerebellar GCMs might be suspected in the presence of large hemorrhagic intra-axial mass with "bubbles of blood," multi-cystic appearance, surrounded by hemosiderin ring, fluid-fluid levels, and accompanying edema-mass effect. Careful radiological study provides a preoperative diagnosis, but its confirmation requires histopathological examination. Complete surgical removal should be attempted when possible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
