“…We included 10 cases from our own retrospective cohort and retrieved 31 cases from the systematic review, as detailed in the Supplementary Flow Chart ( Supplementary Figure S1 ) [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. All were primary SFT with a STAT6-positive pathological diagnosis.…”

“…Although some features have been described to identify spinal SFT, they are not diagnosed correctly on MRI, because of their rarity, lack of specific features, and variety of radiological presentations [ 21 ]. Depending on the radiological type of the lesion, they are misdiagnosed as schwannomas, meningiomas, hemangioblastomas, metastases from solid cancers, ependymomas, and osteosarcomas [ 3 , 6 , 8 , 13 , 18 , 19 , 20 ]. Even in cases when a biopsy was performed before surgical resection, in the literature review, the diagnosis was not obtained correctly [ 18 , 19 ].…”

All solitary fibrous tumors (SFT), now histologically diagnosed by a positive nuclear STAT6 immunostaining, represent less than 2% of soft tissue sarcomas, with spinal SFT constituting a maximum of 2% of them, making these tumors extremely rare. We provide an up-to-date overview of their diagnosis, treatment, and prognosis. We included 10 primary STAT6-positive SFT from our retrospective cohort and 31 from a systematic review. Spinal pain was the most common symptom, in 69% of patients, and the only one in 34%, followed by spinal cord compression in 41%, radicular compression, including pain or deficit, in 36%, and urinary dysfunction specifically in 18%. Preoperative diagnosis was never obtained. Gross total resection was achieved in 71%, in the absence of spinal cord invasion or excessive bleeding. Histologically, they were 35% grade I, 25% grade II, and 40% grade III. Recurrence was observed in 43% after a mean 5.8 years (1 to 25). No significant risk factor was identified, but adjuvant radiotherapy improved the recurrence-free survival after subtotal resection. In conclusion, spinal SFT must be treated by neurosurgeons as part of a multidisciplinary team. Owing to their close relationship with the spinal cord, radiotherapy should be considered when gross total resection cannot be achieved, to lower the risk of recurrence.

“…SFT is a rare neoplasm of mesenchymal origin, most commonly originating from the pleura[ 6 ]. However, it can occur in multiple parts of the body, including the meninges[ 7 ], spine[ 8 ], pancreas[ 9 ], pelvis[ 10 ], adrenal gland[ 11 ] and liver[ 12 ]. SFT of the liver is extremely rare, 84 cases reported in the literature from 1958 to 2016 according to a review by Chen and Slater[ 13 ].…”

Solitary fibrous tumor (SFT) is a rare mesenchymal tumor. Given its origin, it can appear in almost any location. In the literature, only 50 cases of SFT in the liver parenchyma have been reported. Despite its rarity, this entity should be included in the differential diagnosis of liver masses. We report the first case with imaging data from five years prior to diagnosis, which was treated by right portal embolization and arterial tumor embolization, and subsequent liver resection. We also present an exhaustive review of the cases described to date.

“…However, SFTs have been found to occur in any site, including the spine. Spinal SFTs are always classified as intramedullary (58%), intradural extramedullary (24%), or extradural (18%) ( 9 , 10 ). More importantly, as far as we know, no previous reports have described a malignant and metastatic SFT occurred in the thoracic vertebrae.…”

Case Report: A Malignant Liver and Thoracic Solitary Fibrous Tumor: A 10-Year Journey From the Brain to the Liver and the Spine

Solitary fibrous tumors are rare neoplasms that originate from mesenchymal tissues and have been found to occur in any site, including the spine and liver. Although most of solitary fibrous tumors have benign features, only 10–20% are malignant and prone to metastasis. No previous reports have described the malignant and metastatic Solitary fibrous tumor arising in both of the liver and thoracic vertebrae. In this article, we present the case of a 60-year-old woman who underwent gross total resection of a meningeal tumor in 2007. She presented 10 years later with a thoracic vertebral mass that caused relentless pain and a lesion in the right lobe of liver. She underwent marginal excision of the T3 tumor with T2-4 pedicular screw fixation in March 2017, then right hemi-hepatectomy was performed to remove the liver lesion in June 2017. Both of the lesions were confirmed to be a metastatic and malignant tumor after surgery. The literature lacks randomized controlled trials and large studies that define the natural history of malignant solitary fibrous tumors and recommendations of precise management plan for the disease. However, the best choice for treatment is gross total resection, which probably provide the optimal treatment to achieve long-term disease-free survival.
