Hemangiopericytoma of the Meninges: Mayo Clinic Experience

Abstract

Goellner, John R., Laws, Edward R., Jr., Soule, Edward H., and Okazaki, Haruo: Hemangiopericytoma of the meninges. Mayo Clinic experience. Am J Clin Pathol 70: 375–380, 1978. A study of 26 emangiopericytomas of the meninges revealed that the histologic appearance—including ultrastructural features—was similar to that of hemangiopericytomas of soft tissues. Both sexes were affected, and occurrence was most frequent in the adult years, with no symptoms specific for the lesions. The lesions were characterized by an aggressive course, with recurrence in 80% of the patients, and metastases in 23%; thus, the importance of recognizing the lesion pathologically is emphasized.
