Cavernous malformations of the optic nerve and chiasm: illustrative case

CMs of the optic pathway most often present with clinical manifestations of vision loss and headaches. They are difficult to diagnose and can commonly be confused with other hemorrhagic lesions in this region. With a high index of suspicion guided by the clinical and imaging features, one can narrow the differential to include CM. Surgery remains the primary modality of management when symptomatic, similar to intraparenchymal CMs. https://thejns.org/doi/10.3171/CASE24742.
