Angiomatous meningioma in the parietal region dura of a 53-year-old man
This case came to me in consultation from an outlying hospital. It was an enhancing, dural-based mass on MRI. The referring pathologist wondered whether it was a supratentorial hemangioblastoma. The ultimate diagnosis, though, was angiomatous meningioma, a World Health Organization (WHO) Grade I tumor. Grade I tumors are generally well circumscribed, slowly progressive, and can often be cured by resection alone. The photomicrograph of the tumor below shows the meningothelial cells interrupted my numerous blood vessels.
