Abstract
Solitary fibrous tumor is a very rare mesenchymal tumor that occurs mostly in the pleura, and there are few reported cases of a presence in the central nervous system, particularly in the cerebellum. In 2016, the WHO classified solitary fibrous tumors into grade I. In this article, we present a case of malignant solitary fibrous tumor recurring 8 years after surgery in a 63-year-old male. Magnetic resonance imaging showed low to intermediate mixed signal intensity on T1W1. Immunohistochemical staining positivity for Vimentin, CD99, CD34 and Bcl-2, it is consistent with the immunohistochemical characteristics of solitary fibrous tumor. We resected the patient's tumor, and the patient was followed up for 3 months with no signs of recurrence. Solitary fibrous tumors are very rare in the central nervous system. Immunohistochemical staining positivity for CD34 and Bcl-2 is strongly expressed in most solitary fibrous tumor. Surgical resection is the preferred treatment. Due to the small number of cases, the biological behavior and prognosis of this tumor need to be further explored.

Abstract
OBJECTIVE To investigate the MR imaging diagnostic features of intracranial solitary fibrous tumors (ISFTs). MATERIALS AND METHODS Seven patients (mean age of 52.9 years; M:F=3:4) with histopathologically proven ISFTs were identified at our institute. Clinical presentations and pathological features were reviewed. MR Imaging findings including signal intensity, gadopentetate dimeglumine enhanced pattern, and diffusion-weighted imaging (DWI) characterization of the tumors were retrospectively evaluated. RESULTS Six tumors showed a multi-lobular contour. Five tumors showed heterogeneous signal intensity, and two tumors showed homogeneous signal intensity on T1WI. Low signal intensity linear, curved or interlacing lines were observed within the tumors in all seven cases. Seven tumors demonstrated moderate or strong enhancement, six showed heterogeneous enhancement, and one homogenous enhancement. All tumors showed heterogeneous signal intensity on DWI.A ring-like high signal intensity band distributed around within the tumor was noted in six cases on DWI. CONCLUSION Diagnostic evidence for ISFT on MR image includes heterogeneous signal intensity, intense enhancement of T2 signal intensity, low signal intensity lines within the tumor, heterogeneous signal intensity on DWI and a ring-like band around the tumor on DWI.

Abstract
Solitary fibrous tumours/haemangiopericytomas (SFT/HPC) are fibroblastic mesenchymal neoplasms that harbour a genetic fusion of NAB2/STAT6. There are few reported cases in the central nervous system (CNS), of which spinal tumours are minority. We present a case of a 63-year-old woman with progressive paraparesis and a sensory level of T6. On the MRI we detected an intradural extramedullary lesion on T9-T10. We performed a laminectomy with an intraoperative ultrasound study in which we observed a heterogeneous lesion with an infiltrating pattern affecting the medulla at several points, and resection of the lesion. Immunohistological findings revealed positivity for vimentin, CD34 and STAT6; Ki-67 was 2%. A final diagnosis of SFT/HPC with SFT phenotype was made. SFT/HPC of the CNS is a rare neoplasm that should be taken into account in the differential diagnosis of these kinds of lesions, as clinical and MRI findings often lead to errors in diagnostic approach. The support of intraoperative ultrasound can assist in surgical decision-making.

Abstract
INTRODUCTION Solitary fibrous tumor (TFS) is a rare tumor of mesenchymal origin, located mainly in the pleura. It is extraordinarily infrequent find it at the intraespinal level, being the thoracic region the most frequent. CASE PRESENTATION We present the case of a 48-year-old patient with progressive ascending lower limb and myelopathy of one month of evolution, with intraspinal location at the D3-D4 level. It was surgically operated by posterior dorsal approach and D3-D4 laminoplasty, with an intradural tumor with an intramedullary component of approximately 18×12mm. The resection was complete and the pathological anatomy gave the diagnosis of solitary fibrous tumor. The patient is currently asymptomatic. DISCUSSION Complete tumor resection and histopathological features are the main prognostic factors. Surgery have a main role in this type of neoplasia. CONCLUSION There are few case published of solitary fibrous tumor with intraspinal localization. We apport another case to the literature.

Abstract
Solitary fibrous tumours (SFTs) are relatively rare tumours that were originally thought to arise from the pleura but have thereafter been demonstrated as occurring anywhere in the body. These tumours are generally considered benign but have frequently been noted for recurrence and local invasion. Furthermore, their indolence is controversial due to increasing evidence implicating the existence of a spectrum that includes hemangiopericytoma (HPC). Stereotactic radiosurgery (SRS) has been well characterised in the treatment of benign, malignant and vascular conditions, and it appears to be a reasonable option as adjuvant or recurrent treatment for intracranial SFTs. We present in this case the first complete description of an SFT of the orbit treated by SRS as well as a systematic review of available English literature for intracranial SFTs treated by SRS. We report effective local tumour control in our case and conclude that SRS is a reasonable treatment option for recurrent SFT.

Abstract
BACKGROUND Intracranial malignant solitary fibrous tumor (MSFT) is extremely rare. The authors report a case of MSFT of the right occipital lobe with a rapid recurrence and bilateral lung, multiple bone metastasis. CASE PRESENTATION The patient was a 25-year-old male presenting with headache, nausea and visual disturbances without obvious cause. Three times right-side occipital craniotomies were performed and two times postoperative conformal radiotherapy were administered within one year. 4 months after the third time of right-side occipital craniotomy, the patient felt right chest pain and neck pain. Positron emission tomography/computed tomography (PET/CT) showed tumor recurrence of the right occipital lobe and bilateral lung metastasis, multiple bone metastasis including: vertebrae, libs, the left iliac wing, sacrum, the right ischium and upper parts of both femurs. Ultrasound guided puncture biopsy of left-side back of the neck and CT guided puncture biopsy of the third lumbar vertebra were performed. General sample showed grayish white or grayish red with irregular shape. Histopathologically, the tumor was composed of areas of alternating hypercellularity and hypocellularity with spindle-shaped cells, which arranged as fascicular, storiform pattern or patternless pattern, with intervening irregular eosinophilic collagen bundles. Some areas showed hemangiopericytoma-like perivascular pattern and perivascular hyalinization. Tumor cells were pleomorphic with mitotic counts of more than 4 per 10 high power fields and showed coagulative necrosis. Immunohistochemically, tumor cells were diffusely positive for vimentin and CD99, focal positive for CD34, bcl-2 and Actin. Ki-67 labelling index was more than 40%. The final pathological diagnosis was MSFT of the right occipital lobe, metastatic MSFT of left-side back of the neck and the third lumbar vertebra. CONCLUSION The MSFT of the right occipital lobe with recurrence and bilateral lung, multiple bone metastasis is extremely rare. Although intracranial MSFT is extremely rare, it should be considered in the differential diagnosis. Definite diagnosis depended mainly on pathological morphology and immunohistochemistry. The prognosis of MSFT is poor due to recurrence and metastasis. Complete resection of intracranial MSFT is difficult, and carful follow-up is needed.

Abstract
Background: Little is known on the long-term course of patients treated for intracranial solitary fibrous tumors (iSFT). We therefore retrospectively reviewed the charts of our patients who underwent Gamma Knife radiosurgery (GKRS) for iSFT at Klinik Im Park in Zurich and who were treated by one of the authors. Between 1994 and 2009, two patients underwent GKRS for iSFT at Klinik Im Park. Case Description: One patient underwent altogether five radiosurgical treatments and two craniotomies for iSFT and its local recurrences. The other patient underwent two craniotomies and one radiosurgical treatment for iSFT. Both patients maintained a Karnofsky performance score 100 during follow-up and both were long-term survivors with a follow-up of 9 and 17 years, respectively. Conclusion: A close follow-up of patients with iSFT and repeat radiosurgery or surgery when indicated seems to lead to a favorable long-term outcome.
