“…In general, SFT appears as isointense to slightly high on T1WI and isointense on T2WI, compared with gray matter. T1WI demonstrated isointense to slightly high signals (27,28,36) and isointense mixed signals (36) in the case of cystic degeneration and necrosis. In addition, T2WI demonstrated slightly high or isointense mixed signals (27,36), and isointense mixed signals in the case of cystic degeneration and necrosis (36).…”

“…Cystic degeneration and necrosis in the tumor were common, but there was no calcification (27,28,40,41). The density of the tumor following necrosis and cystic degeneration was uneven and destruction of the skull adjacent to the tumor may occur (27,28,40,41).

“…Previous CT scans demonstrated high or equal density. The majority of boundaries were clear; however, a small number of the boundaries with the brain tissue were not clear (27,28,40,41). Cystic degeneration and necrosis in the tumor were common, but there was no calcification (27,28,40,41).…”

“…Sugiyama et al (27) reported on an 86-year-old male with SFT, which was located in the right parietal lobe and invaded the parietal bone, who presented with sustained progressive motor weakness in the left lower extremity for 1 month. Another study reported on a 30-year-old male with SFT, which was located near the right temporal lobe and led to the thickening of the temporal bone of its neighbor; the patient developed left facial nerve paralysis and dysarthria, and decreased muscle strength of the left upper and lower limbs (28).…”

Solitary fibrous tumor (SFT) of the central nervous system is a rare spindle cell tumor of mesenchymal origin. The present study reports the case of a 44-year-old male patient with SFT. Magnetic resonance imaging demonstrated that the majority of the intracranial tumors exhibited uneven low signals on T1-weighted imaging (T1WI) and low mixed signals on T2WI, and there was an enhancement on enhanced scanning. Furthermore, the distal part of the left occipital lobe exhibited hypersignals on T1WI and T2WI, and this was significantly enhanced following enhanced scanning. The lower part of the scalp exhibited low signals on T1WI and high signals on T2WI, and there was no notable enhancement following enhanced scanning. Magnetic resonance spectroscopy demonstrated an elevated choline/creatine peak in the solid part of the tumor. Under the microscope, the tumor exhibited characteristic 'staghorn-shaped' blood vessels. As SFT is difficult to differentially diagnose via imaging, immunohistochemical analysis of CD34, vimentin and signal transducer and activator of transcription 6 was performed for the definitive diagnosis of SFT. Of note, surgical resection was the preferred treatment for SFT; however, due to the rarity of the tumor, subsequent adjuvant therapy and prognosis require further investigation.

Solitary fibrous tumors (SFT) are very rare, particularly those of the central nervous system (CNS), and they have mesenchymal origin. Here, we present the case of a 46-year-old man who, a year after suffering a head injury, lost consciousness for an hour. He had therapy after developing paralysis in his left arm and left foot after three months. A month and a half earlier, he had a bad headache, which triggered an examination. The right temporal frontal lesion on magnetic resonance imaging seems to be a sizable, well-defined extra-axial solid lesion with lobulated edges, predominantly isointense to the white matter with dispersed patches of hypointensity hole on T1WI. The lesion is isointense to the gray matter on T2WI, with sporadic hypointensities. Along the right anterior eminence with the bulk medially, thick, smooth dura mater is seen. A rise in the choline peak was seen in the MRI spectra. The right frontal lobe's white matter showed a little hyperintensity but no signs of angioedema-related diffusion limitation. The pathological diagnostic of the tumor was a grade 3 solitary fibrous tumor after it was surgically excised during a right frontal craniotomy with nearly an entire resection. S100, CD34, STAT Positivity for 6, CK, and KI67 were found during an immunohistochemistry study, and it was done since SFT is challenging to differentially detect through imaging. The patient had extra adjuvant therapy in the form of whole-brain external beam radiation (54 Gy/30#@1.8Gy/#@5#/week) due to the tumor's grade 3 status. Additional research and observation are needed for the prognosis.
