"Dural metastases, also known as pachymeningeal metastases, are a relatively common cause of dural masses, though less common than brain metastases and meningiomas. They can occur both within the spine and intracranially; this article focuses on intracranial dural masses."
"meningiomas: can look indistinguishable; dural-based mass with "dural tail", hyperostosis and calcification; MRS: increased alanine peak and no lipid/lactate peak 18"
