Gliomas of the optic pathways that occur in adults are rare tumours. The tram-track-like calcification of the optic nerve, which classically occurs with meningioma, has not been reported so far in optic pathway gliomas. Here, we present a case of high-grade glioma of the optic pathway with tram-track-like calcification of the optic nerve in a 42-year-old male. This case enhances our understanding of the MRI features of adult malignant optic pathway glioma.
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.
