Case Discussion

The patient went on to have a craniotomy and resection of this highly vascular mass. Histology confirmed the diagnosis of a solitary fibrous tumor.

Note: at the time of diagnosis this tumor was known as a hemangiopericytoma. Under the 5th Edition (2021) of the WHO classification of CNS tumors, it is now considered a solitary fibrous tumor of the dura.
