“…The addition of postoperative radiotherapy is the norm and has shown a significant reduction in the rate of local recurrence when compared with surgery alone. [ 5 ] The high vascularity of HPC can be a challenge for the surgeon. [ 4 ]…”

“…Focal positivity of EMA in an HPC is also known. [5] Non-CNS HPC and solitary fibrous tumor (SFT) are considered by pathologists as two variants of a single tumor entity now subsumed under the entity SFT. Recent detection of frequent NAB2-STAT6 fusions in both, HPC and SFT, has provided additional support for this view.…”

First reported case of simultaneous occurrence of hemangiopericytomas(HCP) at multiple sites of craniospinal axis in a thirty four year male is presented. Patient presented with neck pain for 1 year, and one episode of simple partial seizure involving his left lower limb. He was diagnosed as having HCP in right middle one third parasagittal region, and C4,5 vertebral bodies. Another lesion was present in L5 vertebra, which was radiologically similar to the cervical lesion, but not biopsy proven. High index of suspicion, and low threshold for screening, for coexistence of spinal HCP, in patients harboring cranial HCP's and complaints of back pain.

Solitary fibrous tumor (SFT) of the central nervous system, previously named and classified with the term hemangiopericytoma (HPC), is rare and accounts for less than 1% of all intracranial tumors. Despite its benign nature, it has a malignant behavior due to the high rate of recurrence and distant metastasis, occurring in up to 50% of cases. Surgical resection of the tumor is the treatment of choice. Radiotherapy represents the gold standard in the case of post-surgery residual disease, relapse, and distant metastases. In this context, imaging plays a crucial role in identifying the personalized therapeutic decision for each patient. Although the referring imaging approach in SFT is morphologic, an emerging role of positron emission tomography (PET) has been reported in the literature. However, there is still a debate on which radiotracers have the best accuracy for studying these uncommon tumors because of the histological or biological heterogeneity of SFT.

“…7 There are few case reports showing usefulness of FDG PET/CT in the initial staging and recurrent diseases of HPC in the literature except sinonasal location. 7,9,10 Due to the fact that PET scans the whole body, it can be very useful imaging tool in both initial staging and follow-up of malignant HPC.…”

Hemangiopericytoma is an unusual tumor that arises from vascular smooth muscle cells. It is mainly experienced in 4th to 5th decades of life and soft-tissue masses are frequently located in lower extremity, pelvis, and retroperitoneum. A 29-year-old man presented with a mass lesion in the right nasal cavity associated with shortness of breath as a result of nasal obstruction. An incisional biopsy was reported as sinonasal type hemangiopericytoma. The initial staging F-18 flourodeoxyglucose PET/CT successfully demonstrated severe hypermetabolism in the primary tumor location and mild-to-moderate hypermetabolism in the right upper jugular lymph node.
