“…SFT/HPC is a rare and potentially aggressive lesion and SFT/HPC of bone is even rarer, accounting for 0.1% of malignant primary bone tumors and 11% of malignant vascular bone tumors [11]. Because of the low incidence of spinal osseous SFT/HPC, the biological behavior and prognosis factors were poorly understood.…”

recurrence being 36.6 (median 28, range 12-73) months. Our results indicate that grade III is an adverse prognostic factor for both recurrence and over survival (OS) for spinal osseous SFT/HPC, while total resection, especially TES, is a positive prognostic factor. Conclusions Spinal osseous SFT/HPC is a challenging clinical entity given its high local recurrence rate. Surgical management plays a crucial role in the whole treatment of spinal SFT/HPCs and total excision, especially TES, should be strived for whenever possible. Postoperative radiotherapy is recommended to lower the recurrent rate. This study also confirms that pathology grade III is an adverse prognostic factor for spinal osseous SFT/HPCs.

“…CT scan is superior to X-ray in evaluating bone destruction, and MRI is more accurate in detecting extraosseous extent of the tumor [11,21]. MRI, especially with gadolinium enhancement, remains as an important choice for better definition of lesions and for evaluating relations with the thecal sac, spinal nerves and major vessels.…”

“…Flow void represents rapid blood flow through either dilated arteries or dilated veins, 3 and it appears most often among high-flow vascular lesions (such as aneurysm and arteriovenous malformation), some vascular tumors (such as hemangiopericytoma, 4 hemangioblastoma 5 ), malignant neoplasms (such as glioblastoma 6 ), and even benign neoplasms (such as pituitary adenoma and Schwannoma 7,8 ).…”

Papillary meningioma is an uncommon meningioma subtype of World Health Organization grade III. It could show some radiologic profiles pointing to malignant behavior, such as a cystic change, a heterogeneous enhancement, and an ill- defined border. However, to date, the radiologic profile described in this article has not been reported in previous literatures, and it is just the characteristic being considered as the major cause for patients’ death. A 16-year-old adolescent boy with a 6-month history of headache was admitted to our department on June 28, 2012. Magnetic resonance imaging showed a giant well-defined mass in the left temporal region, with a severe flow void on T2-weighted image and an abundant stripelike enhancement on T1-weighted contrast-enhanced scan. In view of its middle cranial fossa location (one predilection site for meningioma), meningioma was suspected preoperatively. A regular left frontotemporal craniotomy was performed. Unexpectedly, extreme hemorrhage happened intraoperatively, and it was difficult to stop the bleeding. After identification of no hemorrhage in the operative cavity through intraoperative magnetic resonance imaging, the operation was finished, with an overall blood loss of 15,000 mL. The patient died of brain stem dysfunction the second day after the operation.

“…In the radiology literature, there are only case reports or small case series reports of bone HPC (7)(8)(9)(10)(11)(12)(13). Although most of bone HPC demonstrate as destructive or lytic lesions (7)(8)(9)(10)(11)(12)(13), radiographic findings are non-specific as well (14).…”

Abstract. Bone hemangiopericytoma (HPC) is extremely rare, and its clinical manifestations and radiographic features are nonspecific. There are few case reports about application of F18-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in HPC. A total of four subjects with pathologically diagnosed bone HPC had FDG PET/CT for staging and/or restaging bone HPC. Medical records were retrospectively reviewed for radiological, pathological and follow-up information. All primary bone and metastatic lesions demonstrated high FDG avidity on PET/CT, which also revealed the adjacent soft tissue involvement and synchronous lesion. PET/CT correctly detected metastatic lesions in 1 patient. Furthermore, 3/4 patients with available laboratory data had hypocalcemia, but normal phosphorus levels when HPC existed as primary lesions or metastatic disease; however, normalization of calcium levels when they were disease-free. The results suggested that FDG PET/CT could be effectively used for staging, surveillance and detection of recurrent/metastatic disease in HPC. There may be an association between bone HPC and hypocalcemia.
