Development of a preclinical model for NF2‐related meningiomas: murine meningiomas show radiological features of human meningiomas. Because meningiomas are routinely detected and followed by MRI in patients, we sought to determine whether small animal MRI could detect leptomeningeal pathology (meningothelial proliferations and meningiomas) in the living mouse. Here, NF2 is linked to meningioma.
