“…It is interesting to note that the reticulum pattern illustrated is, in areas, not unlike that revealed in the present tumor, as well as in other hemangiopericytomas, and a prominence of vessels was noted by these authors. Similarly, the retic¬ ulum pattern and cellular detail of the meningiomas classified as angioblastic by Cushing and Eisenhardt,10 and previously by Bailey,Cushing,and Eisenhardt,8 are identical with those of this tumor and other hemangiopericytomas. This similarity prompted Begg and Garret,8 in their report of a case of meningeal hemangiopericytoma, to consider the angioblastic meningiomas as actually representing hemangiopericytomas.…”

“…1 The WHO officially recognized hemangiopericytomas as unique CNS tumors in 1993. 23 Distinguishing between hemangiopericytomas and meningiomas, which requires a tissue diagnosis, has clinical significance, as patients with hemangiopericytomas have a worse overall prognosis and require more vigilant follow-up for recurrence and metastasis.…”

Object Central nervous system (CNS) hemangiopericytomas are relatively uncommon and unique among CNS tumors as they can originate from or develop metastases outside of the CNS. Significant difference of opinion exists in the management of these lesions, as current treatment paradigms are based on limited clinical experience and single-institution series. Given these limitations and the absence of prospective clinical trials within the literature, nationwide registries have the potential to provide unique insight into the efficacy of various therapies. Methods The authors queried the Surveillance Epidemiology and End Results (SEER) database to investigate the clinical behavior and prognostic factors for hemangiopericytomas originating within the CNS during the years 2000–2009. The SEER survival data were adjusted for demographic factors including age, sex, and race. Univariate and multivariate analyses were performed to identify characteristics associated with overall survival. Results The authors identified 227 patients with a diagnosis of CNS hemangiopericytoma. The median length of follow-up was 34 months (interquartile range 11–63 months). Median survival was not reached, but the 5-year survival rate was 83%. Univariate analysis showed that age and radiation therapy were significantly associated with survival. Moreover, young age and supratentorial location were significantly associated with survival on multivariate analysis. Most importantly, multivariate analysis using the Cox proportional hazards model showed a statistically significant survival benefit for patients treated with gross-total resection (GTR) in combination with adjuvant radiation treatment (HR 0.31 [95% CI 0.01–0.95], p = 0.04), an effect not appreciated with GTR alone. Conclusions The authors describe the epidemiology of CNS hemangiopericytomas in a large, national cancer database, evaluating the effectiveness of various treatment paradigms used in clinical practice. In this study, an overall survival benefit was found when GTR was accomplished and combined with radiation therapy. This finding has not been appreciated in previous series of patients with CNS hemangiopericytoma and warrants future investigations into the role of upfront adjuvant radiation therapy.

“…Intracranial HPCs were defined as histologically and immunohistochemically distinct from meningiomas after the first case of HPC arising from the dura mater was reported. 4) The revised World Health Organization (WHO) classification includes HPCs as mesenchymal tumors. 16) However, HPCs are more aggressive tumors because of the tendency to recur and metastasize even after gross total removal (WHO grade II or III).…”

A 31-year-old female presented with a particularly rare hemangiopericytoma (HPC) in the right lateral ventricle manifesting as a 6-month history of visual disturbance and headache. Left hemianopsia and choked disc were identified by an ophthalmologist who referred her to us. Magnetic resonance imaging demonstrated a 5-cm homogeneously enhanced mass in the trigone of the right lateral ventricle. The tumor was totally removed by two stage surgery. The histological findings were consistent with HPC. HPC is very important to differentiate from meningioma and solitary fibrous tumors because HPC is more aggressive. The histological and immunochemical findings are important for the differential diagnosis. The present case showed no local recurrence or metastasis without radiation therapy for 4 years, indicating that radiation therapy is not absolutely imperative for patients with intraventricular HPC showing low MIB-1 staining index after total removal.
