High-resolution MRI demonstrates that more than 90 of small intracranial melanoma metastases develop in close relationship to the leptomeninges

摘要

Despite classic teaching that intracranial metastases typically arise at the gray–white matter junction, small intracranial melanoma metastases (IMM) are frequently observed at the interface between the cortex and leptomeninges (ie, “corticomeningeal interface”), suggesting possible leptomeningeal origin.
