If meningeal hemangiopericytoma could be diagnosed prior to operation, the neurosurgeon might be better prepared to deal with excessive bleeding during the operation. This type of tumor should be completely excised because of the high risk of recurrence and remote metastasis.

VASCULAR tumors have been of particular interest to surgeons for their unusual clinical and pathologic characteristics and because of the technical ingenuities frequently required for their removal. Stout's description of a previously unreported tumor of vascular origin, which he named hemangiopericytoma, 1 has caused increased interest in the subject.

Nasal hemangiopericytoma is difficult to diagnose preoperatively or before examining a histologic specimen. It is a locally invasive tumor with an excellent five-year prognosis, but which requires lifetime follow-up. The patient reported was treated by aggressive local surgical treatment of the tumor followed by systemic therapy for multiple myeloma.
