“…Pathologic examination of the surgical specimen showed classic features of glomangiopericytoma [199]. A case study by Aras et al also reported that PET/CT images showed marked hypermetabolism (SUVmax of 20.9) in the primary tumor, which was reported as a sinonasal-type hemangiopericytoma [200].…”

Sinonasal cancers are uncommon malignancies with a generally unfavorable prognosis, often presenting at an advanced stage. Their high rate of recurrence supports close imaging surveillance and the utilization of functional imaging techniques. Whole-body 18F-FDG PET/CT has very high sensitivity for the diagnosis of sinonasal malignancies and can also be used as a “metabolic biopsy” in the characterization of some of the more common subgroups of these tumors, though due to overlap in uptake, histological confirmation is still needed. For certain tumor types, radiotracers, such as 11C-choline, and radiolabeled somatostatin analogs, including 68Ga-DOTATATE/DOTATOC, have proven useful in treatment planning and surveillance. Although serial scans for posttreatment surveillance allow the detection of subclinical lesions, the optimal schedule and efficacy in terms of survival are yet to be determined. Pitfalls of 18F-FDG, such as post-surgical and post-radiotherapy crusting and inflammation, may cause false-positive hypermetabolism in the absence of relapse.

“…This emphasizes the need for long-term follow-up in patients with malignant SFT variants 5 . Several studies and case reports showed variable 18 F-FDG uptake of primary tumors in different locations as well as in metastases 6–15 . Although some studies showed slightly higher 18 F-FDG uptake in malignant SFT of the pleura compared with benign pleural variants, 16,17 there have also been reports of 18 F-FDG-negative malignant variants 18 .…”

A Rare Case of Metastatic Solitary Fibrous Tumor (Hemangiopericytoma) of the Dura on 18F-FDG PET/CT

et al. 2021

Solitary fibrous tumor is a rare neoplasm of mesenchymal origin. It can arise in various locations, most commonly in the pleura. It encompasses a heterogeneous group of histological patterns with different biological behavior. In some cases, metastases occur, sometimes years after the initial diagnosis. We report a case of metastatic meningeal hemangiopericytoma, also called solitary fibrous tumor of the dura, exhibiting liver metastases and muscle metastases 5 years after resection and adjuvant radiotherapy of the primary tumor.

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.
