Solitary fibrous tumor of the thoracic spine

Solitary Fibrous Tumor of the Central Nervous System

“…162,171,171 CD34 immunohistochemistry was applied to all reported cases, except for one in which the use of this marker was not mentioned in the report. 168 In a few cases, actin and desmin were variably positive. 89,101,108 S-100 protein, cytokeratins, and EMA were almost always negative.…”

“…[We did not include in our tabulation the following cases: 7 cases of meningeal SFT 76,100,107,145,154 Of the 42 cases for which the exact location was stated, in decreasing order of frequency, 20 were thoracic (including 1 epidural lesion metastatic from an intracranial primary initially diagnosed as fibrous meningioma), 108 (Table 1 intraspinal cases marked with an asterisk). [We included in our tabulation 1 case of (para)vertebral SFT for which the precise location (likely extradural) was not established, 150 and a case of spinal thoracic SFT of Cincu et al, 168 despite the fact that the authors did not use CD34. We excluded a sclerosing fibrous tumor of the cauda equine reported by Hisaoka et al,192 in 1993 probably the first SFT (sclerosing type) ever reported, which showed fibroblastic differentiation by ultrastructural examination but was not analyzed immunohistochemically, and a case by Kashiwazaki et al, 193 an intraspinal subpial HPC with marked extramedullary growth and histopathological features that would fit the diagnostic criteria of SFT (with HPC-like pattern).…”

“…Although most intracranial SFT (148 of 170) were extra-axial dural-based tumors, 22 (accounting for 12.94%) had no apparent connection with the dura. Of the latter, 13 were intraventricular, 90,103,105,108,132,133,135,142,146,156,157,169,172 occasionally found attached to the choroid plexus, 108,135,172 3 were parenchymal lesions deeply located in the brain substance, 91,94,108 5 arose from the proximal (intradural) segment of the cranial nerves, 65,97,99,131,167,168 and 1 at the cerebello-pontine angle 139 (Table 1). [We did not include in our tabulation the following cases: 7 cases of meningeal SFT 76,100,107,145,154 Of the 42 cases for which the exact location was stated, in decreasing order of frequency, 20 were thoracic (including 1 epidural lesion metastatic from an intracranial primary initially diagnosed as fibrous meningioma), 108 (Table 1 intraspinal cases marked with an asterisk).…”

Primary Solitary Fibrous Extradural Tumor of Thoracic Spine: A Case Report

“…Imaging does not have any pathognomonic features to determine its origin and diagnosis can be confirmed only by histopathology. 2 MRI is nonspecific and lesions are iso-to hypointense on T1 and T2 with the presence of vascular flow voids and heterogeneous contrast enhancement. Tumor degeneration can produce cystic necrosis causing hyperintensity on T2 signals.…”

Solitary fibrous tumors of the spine: a pediatric case report with a comprehensive review of the literature

“…We identified 65 previously published papers with 83 cases. [1][2][3][4][7][8][9][10][11][12][13][14]16,17,[20][21][22][24][25][26][27][28][29][30][31][32][33][34][35][37][38][39][40]42,43,[46][47][48][49][50][51][52][53][54][55][56][57][58][59]62,[64][65][66]…”
