Evans VMD, MS. Corresponding Author. Section of Radiology, University of Pennsylvania, School of Veterinary Medicine, Philadelphia, Pennsylvania. Meningeal hemangiopericytoma is a rare neoplasm arising from perivascular pericytes. Accounting for < 1% of all brain tumors, these neoplasms are characterized by a high local recurrence rate and metastatic potential.

Imaging findings were indistinguishable from an aggressive bone tumor such as Ewing's sarcoma. Imaging findings are presented and discussed. Our case indicates that MHP should be considered in the differential Department of Radiology, Affiliated Hospital of North Sichuan Medical College, Sichuan Province, China. ∗Correspondence: Yong Du, Wenhua Road No. 63, Nanchong 637000, Sichuan Province, China (e-mail: dy_nsmc@163.com). Abbreviations: CPA = cerebellopontine angle, CT = computed tomography, HPC = hemangiopericytoma, IAC = internal auditory canal, MRI = magnetic resonance imaging, SFT = solitary The radiology literature has reported a total of five cases of primary pulmonary hemangiopericytoma from two studies. In both, emphasis is placed on radiographic, CT, and MRI features [6, 7]. However, to our knowledge, MR angiography and Doppler sonography findings of hemangiopericytoma arising in the lung have not been documented.

The tumor was unresectable and the patient received postoperative irradiation of 4200 cGy on the pelvis. One year after diagnosis, metastasis to a lumbar vertebra was discovered and additional irradiation of 3900 cGy was applied. One year later, CT showed control of the pelvic tumor Sinonasal-type hemangiopericytoma is an uncommon upper aerodigestive tract tumor of uncertain cellular differentiation.

Unresectable cases can be treated with either RT alone or CRT (inferior outcome). Is there a role for chemo in the management of hemangiopericytoma? Yes. Nasopharyngeal Hemangiopericytoma Epidemiology. Hemangiopericytomas are unusual vascular tumors that occur mainly in adults. They represent 1% of all vasoformative tumors, most of which occur in the lower extremity, retroperitoneum, and pelvis. Approximately 15 to 20% occur in the head and neck region.

Purpose: To describe the MR and CT imaging features of hemangiopericytoma and to identify the characteristics that might distinguish them from meningioma. Methods: We retrospectively reviewed the CT and MR findings in 34 pathologically proved cases of hemangiopericytoma. Hemangiopericytomas are considered malignant lesions (sarcomatous lesions associated with blood vessels). What is the cell of origin of hemangiopericytomas? Hemangiopericytomas were originally thought to originate from pericytes of the smooth muscle cells of vessels but are now felt to be of fibroblastic origin.
