Abstract
Background Hemangiopericytoma (HPC), also known as solitary fibrous tumor (SFT), is a type of soft tissue sarcoma with a special aggressive behavior. The HPC/SFT is locally aggressive with possibility of late recurrence locally or distant extraneural metastasis. The most common location of this HPC/SFT is the lower extremities. The HPC/SFT in the central nervous system (CNS) is very rare, and compared with the brain, it is rarer in the spinal region. However, clinicians also lack an overall understanding of the diagnosis of HPC/SFT in the spinal cord. Case presentation In this study, we report a rare case of primary cervical spine HPC/SFT in a 53-year-old woman. Two to three weeks before admission, she experienced pain and numbness in her left upper extremity. After computerized tomography (CT) and magnetic resonance imaging (MRI), a gross total resection was performed. Obvious neurological improvement was observed postoperatively. The pain and numbness in the patient's left upper limb were relieved subsequently. We then reviewed the literature on HPC/SFT, such as its clinical presentation, imaging characteristics, treatment, and follow-up. Conclusions Diagnosis of HPC/SFT relies on magnetic resonance spectroscopy, enhanced CT, and MRI. Postoperative radiotherapy is strongly recommended to reduce the HPC/SFT recurrence. Immunohistochemical analysis can also help in the differential diagnosis. However; early and long-term follow-up is necessary for patients.

Abstract
Solitary fibrous tumors (SFTs) are rare soft tissue neoplasms that can impact the central nervous system (CNS). SFTs comprise <1% of all primary CNS tumors. Here, we describe a rare case of intradural, extramedullary SFT arising within the thoracic spine that was treated with surgical resection. Histological features were evaluated and revealed a highly cellular tumor with positive expression of BCL2, CD34, CD99, and STAT6 proteins that are consistent with a diagnosis of SFT. We discuss the use of surgical intervention for long-term disease control of spinal SFT and evaluate the role of postoperative radiation therapy in management strategies. Lastly, we review the literature reports of intradural, extramedullary SFTs in the thoracic spine. The importance of molecular characterization by histopathology to properly determine diagnosis and prognosis is emphasized.

Abstract
The management of patients harboring central nervous system (CNS) hemangiopericytomas (HPCs) is a partially answered challenge. These are rare locally aggressive lesions, with potential for local recurrence, distal neural metastasis (DNM), and extraneural metastasis (ENM). Resection, when feasible, remains the initial treatment option, providing histological diagnosis and immediate relief of tumor-related mass effect. Patients receiving surgery alone or surgery and external beam radiotherapy (EBRT) show improved overall survival (OS) and progression-free survival as compared to those undergoing a biopsy alone (p = 0.01 and p = 0.02, respectively). Yet, in many instances, patient and tumor-related parameters preclude complete resection. EBRT or stereotactic radiosurgery (SRS) shares a significant role in achieving local tumor control, not shown to impact OS in HPC patients. The benefits of SRS/EBRT are clearly limited to improved local tumor volume control and neurologic function, not affecting DNM or ENM development. SRS provides acceptable rates of local tumor volume control coupled with treatment safety and a patient-friendly apparatus and procedure. Single-session SRS is most effective for lesions measuring <2 cm in their largest diameter (10 cm3 volume), with prescription doses of at >15 Gy. Systemic HPC disease is managed with various chemotherapeutic, immunotherapeutic, and anti-angiographic agents, with limited success. We present a short discussion on CNS HPCs, focusing our discussion on available evidence regarding the role of microsurgical resection, EBRT, SRS, chemotherapy, and immunotherapy for upfront, part of adoptive hybrid surgery approach or for recurrent HPCs.

Primary epidural hemangiopericytoma of the thoracic spine: Case report and literature review. J Clin Neurosci 2018; 60:142-147.

Abstract
Hemangiopericytoma (HPC) is a rare tumor originating from pericapillary cells. Rarely found in the central nervous system, it is extremely rare in the spinal canal. Because of the low incidence of this tumor, its radiographic features and clinical manifestations have not been extensively studied and reported, therefore, it is often misdiagnosed as a schwannoma or spinal meningioma. We describe an unexpected HPC in a 35-year-old woman who was admitted to the Peking Union Medical College Hospital with a severe backache, sensory abnormalities, and muscle weakness. Magnetic resonance imaging showed an enhancing lesion at T6-7 with severe compression of the spinal cord. Gross total resection was achieved, and subsequently, a marked neurologic improvement was observed. The diagnosis of primary extradural HPC in our patient was confirmed based on postoperative histopathology and immunohistochemistry. Neither recurrence nor metastasis of the tumor was found during the 14-month follow-up, which did not include radiotherapy. To describe the demography, radiologic features, treatment, and prognosis of spinal HPC, a comprehensive literature review was performed and 105 cases of primary spinal HPC from 1958 to 2017 were collected from 39 articles. Although rare, HPC should be considered in the differential diagnosis of intraspinal lesions. Immunohistologic examination is of decisive importance in making the diagnosis. Adequate surgical resection, when feasible, is the first choice of treatment for all cases of HPC; however, the outcomes of radiotherapy and chemotherapy have yet to be determined. Individualized treatment combined with long-term follow-up for each patient is recommended.

Distinctive Characteristic Features of Intramedullary Hemangiopericytomas. Asian Spine J 2015; 9:522-8. [PMID: 26240709 PMCID: PMC4522440 DOI: 10.4184/asj.2015.9.4.522] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2014] [Revised: 01/05/2015] [Accepted: 01/19/2015] [Indexed: 11/30/2022] Open
Abstract
Study Design The retrospective analysis of intramedullary hemangiopericytomas (HPCs) was performed, and the entity was discussed in accordance with the literature findings. Purpose This study aimed at defining distinctive characteristic features of intramedullary HPC with respect to surgical approach and prognosis. Overview of Literature Intramedullary HPCs are extremely rare tumors. They originate from capillary pericytes, supposedly follow the vessels over the spinal cord, and infiltrate deep into the spinal cord without a distinct plane. Their treatments and prognosis are not well-defined in the literature. Methods Our database was retrospectively reviewed for the cases of HPCs. Later on, a literature search was performed to reveal all reported cases of intramedullary HPCs. The following key words were searched in PubMed databases: "hemangiopericytoma and intramedullary," "hemangiopericytoma and spine (spinal) and intradural," and "hemangiopericytoma and spinal cord." The articles were reviewed for patients' demographics features, imaging characteristics, tumor-specific factors (surgical technique, pathological descriptions, and world health organization grades), and postoperative course and prognosis (adjuvant therapies, recurrences, complications, and mortalities). Results A total of seven patients (three male and four female) was reached, with their ages ranging from 15 to 80 years (mean, 32.5 years). The tumors were located majorly in thoracic region (5/7, 71.4%), and only two cases were in the cervical region (2/7, 28.6%). All tumors were completely removed, and only two cases received radiotherapy. No recurrence was reported. Conclusions Complete resection of the intramedullary HPCs seems to be the best management strategy for long-term and recurrence-free survival and in alleviating further need for radiotherapy.

Abstract
PURPOSE Spinal hemangiopericytoma is a rare neoplasm that behaves similar to intracranial hemangiopericytoma, with approximately 60 cases being reported in the literature of which only 10 are located in the intradural extramedullary (IDEM) location. METHODS We report a rare case of recurrent IDEM hemangiopericytoma of dorsal spine in a 16-year-old boy treated with surgery and adjuvant radiotherapy. RESULTS Patient is disease free at 5 years posttreatment with residual neurological deficit, but is able to carry out his activities of daily living. CONCLUSION Gross total resection, if feasible, followed by radiotherapy is the initial treatment of choice as radiotherapy improves recurrence free survival as well as overall survival.

Abstract
Spinal intradural hemangiopericytoma is a very rare tumor and can be characterized by massive bleeding during surgeries, frequent recurrence, and metastasis. However, definite radiologic differential points of hemangiopericytoma are not known. We describe an unexpected hemangiopericytoma case with large bleeding and management of the tumor. A 21-year-old man visited complaining of progressive neck pain and tingling sensation in both hands. Magnetic resonance imaging of his spine revealed C1-2 ventral intradural mass. When the dura was opened, the intradural tumor was placed behind spinal accessary nerves. The tumor was partially exposed only after some accessary nerves had been cut. When internal debulking was performing, unexpected bleeding was noted and it was difficult to control because of narrow surgical field and hypervascularity. Intraoperative spinal angiography and embolization were performed. The tumor was completely removed after embolization. Pathological diagnosis was consistent with hemangiopericytoma. When surgeons meet a flesh-red tumor that bleeds unexpectedly during surgery, hemangiopericytoma may be considered. When feeder control is hard due to reciprocal location of spinal cord, the tumor, and feeders, intraoperative angiography and embolization may be a possible option.

Abstract
PURPOSE Hemangiopericytoma (HPC) is a rare tumor of the central nervous system. Primary spinal occurrence of this tumor is extremely uncommon and cases involving the intramedullary spinal cord are even more rare. The purpose of this study was to explore the clinical features, surgical strategies, outcome and pathology in a consecutive series of patients treated at a single institution. METHODS The authors performed a retrospective review of the clinicopathological characteristics of four patients with a pathological diagnosis of spinal HPC. RESULTS Four cases with intradural as well as intra/extra-medullary components were identified. Gross total resection with no recurrence at the operative site was achieved in the majority of patients with a spinal HPC. One patient had significant recurrence and eventually, succumbed to the disease. CONCLUSION Increased awareness of these tumors' capability to occur intradurally and intramedullarly can help surgeons accurately diagnose and choose an effective plan of care. Gross total resection of hemangiopericytomas is the mainstay of treatment and should be pursued if feasible. Histopathology is essential to the diagnosis.

Abstract
Abstract
BACKGROUND:
Intraspinal hemangiopericytoma (HPC) is a rare and malignant extra-axial tumor with a strong tendency to recur and metastasize. There is a paucity in the literature of large case series of patients with intraspinal HPCs.
OBJECTIVE:
We retrospectively analyzed the clinical radiological and histological features, classification, and treatment of 26 patients with HPCs in the spine.
METHODS:
Twenty-six patients with HPCs in the spine were treated at our institution between 1987 and 2010. Medical records were reviewed retrospectively to collect data on the clinical features, tumor morphology, surgical resection, recurrence, and follow-up.
RESULTS:
The 26 patients were predominantly male, and the mean age at diagnosis was 33.8 years. The intraspinal HPCs were divided into 3 types and 5 subtypes. Most of them involved the neighboring segments and/or caused bony erosion. All tumors were immunohistochemically positive for vimentin and negative for epithelial membrane antigen. All patients underwent at least 1 surgery, and most of them received postsurgical radiotherapy. The 5-year Kaplan-Meier rate of survival was 76%. The 5-year recurrence-free rate of survival was 29.4%. Only the tumor pathological grade was significantly associated with survival time and recurrence.
CONCLUSION:
High-grade tumors had a shorter survival time and recurred earlier than low-grade tumors. Surgical removal and postoperative radiotherapy are critical for the treatment of intraspinal HPCs. However, total resection may not necessary for these tumors. Stereotactic radiosurgery may be a good alternative to control the recurrent lesions.
