“…10,12,20 Hemangiopericytomas, however, are much more aggressive lesions, associated with high rates of local or distant recurrences, [1][2][3]5,[10][11][12]17,18,20,23,27,31 and thus can behave similarly to other malignant lesions. 24 Resection is the initial treatment of choice, 26 but the highly vascular nature of the lesion and the location of some along the skull base results in mortality rates between 9 and 24%.…”

Object Hemangiopericytomas represent a small subset of meningeal tumors. Despite their relatively uncommon nature, they are aggressive tumors known for recurrence. Resection is the standard treatment in most, although regrowth and metastases are common even after resection. The authors evaluate the role of stereotactic radiosurgery in the treatment of recurrent hemangiopericytomas. Methods In a review of the Stanford radiosurgery patient database between 1989 and 2002, the authors found eight patients with recurrent hemangiopericytoma who underwent stereotactic radiosurgery. The mean age of this population was 45.1 years (range 24–67 years). All patients had been previously treated with resection, and five patients (63%) had undergone conventional radiotherapy. The mean radiosurgery dose to the tumor margin was 20.5 Gy (range 16–24 Gy). The mean clinical and radiographic follow-up period was 44 months (range 8–77 months). Of the eight tumors treated with radiosurgery, six decreased in size and two ultimately progressed. There were no radiosurgery-related complications. Conclusions Stereotactic radiosurgery of hemangiopericytomas can result in increased tumor control and should be considered as a treatment option for patients in whom the diagnosis has been established and in whom residual tumor is demonstrated postoperatively. Close clinical and radiographic follow-up evaluation is necessary in this patient population because of the high rate of local recurrence and distant metastases.

A wide spectrum of dural lesions occurs which is mimicking meningioma. The meningeal haemangiopericytoma is a rare tumor of meninges that is difficult to distinguish from meningioma; however both are treated similarly with surgical resection with or without radiotherapy to reduce the risk of recurrence. Macroscopically many haemangiopericytoma resemble to meningioma but are distinct histologically. These tumors show more aggressive natural history. Vascular nature of tumor suggests a different therapeutic approach thus fore warning a surgeon to a potentially more challenging resection.

“…While postoperative radiotherapy is generally recommended for meningeal hemangiopericytoma to reduce the risk of local recurrence, improve the survival rate, and delay recurrence, 3,11,14,17,19) some authors consider that the value of postoperative radiotherapy for meningeal hemangiopericytoma is questionable, since postoperative radiotherapy did not protect against neuraxis and peripheral metastasis. 7,8) However, stereotactic radiosurgery is indicated for recurrent tumors measuring less than 25 mm in diameter 7) and is an excellent alternative to repeated craniotomy in recurrent disease.…”

Meningeal hemangiopericytoma is rare, and only seven cases have manifested as intracranial hemorrhage. We treated two patients with meningeal hemangiopericytoma manifesting as life-threatening massive intracerebral hemorrhage. Case 1: A 66-year-old woman presented with consciousness disturbance and left hemiparesis. Computed tomography showed a mass lesion in the right frontal parasagittal region and massive hematoma in the brain tissue at the medial border of the lesion. Immediate evacuation of the hematoma was performed. Postoperative magnetic resonance imaging revealed a well-enhanced mass lesion with small intratumoral hemorrhage. The tumor was removed totally through a bilateral frontal craniotomy. The postoperative course was uneventful. The histological diagnosis was meningeal hemangiopericytoma. Radiotherapy was not performed. Case 2: A 59-year-old man presented with consciousness disturbance. Computed tomography showed a mass lesion in the right frontotemporal convexity region and massive hematoma in the brain tissue at the medial border of the lesion. His neurological condition was refractory to any treatment and the clinical diagnosis of brain death was confirmed. Autopsy was performed and the histological diagnosis was meningeal hemangiopericytoma. Meningeal hemangiopericytoma manifesting as intracranial hemorrhage is quite rare, but carries the risk of life-threatening massive bleeding from the tumor.
