“…The indications for this procedure include: story of excessive bleeding in previous surgery; hypervascularity tumors; deep tumors with hard access on the early surgical access of the main feed vessels; tumors associated with intratumoral aneurysm. However, in HPCs bigger than 6 cm the embolization did not show intraoperative benefits [14][15][16].…”

“…Currently it could be part of the treatment for HPC: preoperative embolization, total or subtotal surgery resection of the tumor, adjuvant radiotherapy and radiosurgery. However, the chemotherapy do not show efficient in the treatment of HPCI, given its high aggressiveness, but can be considered in cases of peripheral metastasis [15].…”

“…The global survival and the survival free of disease are usually more prolonged when the patients are submmited to Grossly Total Resection (GTR), in comparison with Partial Resection (PR). For this reason, the GTR is usually more widespread today [15].…”

“…It is important to emphasize that the analyzed studies showed that the chemotherapy as neoadjuvant or adjuvant treatment for IHPC was not recommended, because of the high resistance of the tumor to this treatment, but there may be indication in cases of peripheral metastatic disease [15].…”

The hemangiopericytomas (HPCs) are rare tumors of the dural base and correspond of less than 1% of all primary Central Nervous System (CNS) tumors. It usually affects adult males with 40 to 50 years old and has a supratentorial location (70%), followed by posterior fossa (15%) and spine (15%). Generally, it has fast progression and manifests clinically through headache, focal neurological deficits and epileptic seizures. The tumor has high incidence of local recurrence, from 34% to 90%, and it is estimated that the follow-up of these patients should be done for at least 7, 5 years. The percentage of longdistance metastases is lower, 12% to 55%, affecting especially bones, lungs and liver, in decreasing order. The objective of this study is to evaluate the contradictions when approaching these tumors and to analyze a rare case of pediatric involvement. It was prepared a case report and a literature review was made using the data bases MEDLINE®, PubMed and Cochrane, where 31 relevant articles were selected related to the proposed study. The outcome of HPC treatment can change according to the tumor's location in the CNS or extracranial, the tumor's size and the histopathological classification. Therefore, many studies have been proposed observing the answer of the surgical resection, the adjuvant radiotherapy, the radiosurgery and the antiangiogenic therapies.

“…Intraventricular locations are exceedingly rare for intracranial HPC, with only 14 case reports described in the literature (4,5). To the best of our knowledge, our patient is the second case of anaplastic intraventricular HPC.…”
