“…Approximately 3%-5% of adult meningiomas are so-called “cystic meningiomas,” which are meningiomas with a cystic component [19] , [20] , [21] . Although cases of HPC with cystic degeneration have been reported [22] , there have been few reports [ 23 , 24 ] of cystic degeneration in nearly half of the lesions, as in this case. Widespread cystic degeneration may be 1 factor that makes the differentiation between SFT/HPC and meningioma difficult.…”

Intracranial solitary fibrous tumor/hemangiopericytoma (SFT/HPC) is a relatively rare type of tumor that originates from meningeal mesenchyme. A 30-year-old man presented leaning his body to the left and with weakness of his left lower limb. Computed tomography revealed a heterogeneous mass with multiple cystic components and hyperostosis of the right cranial convexity. Magnetic resonance imaging showed the mass was broadly attached to the dura matter with dural tail sign. In addition, the lesion had extensive cystic degeneration and a solid compartment showing low apparent diffusion coefficient values. The patient underwent gross total resection of the intracranial lesion and presented no recurrence within a 12-month follow-up period. Histopathology confirmed SFT/HPC (World Health Organization grade Ⅱ). Although there have been several useful techniques reported to differentiate SFT/HPC from meningioma, in this case the atypical findings for SFT/HPC made it difficult. We report the imaging findings of this case and some literature reviews.

“…A review of the literature was performed by querying the PubMed database utilizing the following search term: ("intraventricular" OR "ventric*") and ("solitary fibrous tum*"). Of the 46 papers returned, nine studies [6][7][8][9][10][11][12][13][14] reported new cases of patients diagnosed with specifically SFTs (not HPC) originating in the lateral ventricles for a total of 10 cases (Table 1). ISFT was first described in 2003.…”

Solitary fibrous tumors (SFTs) are rare tumors thought to be of mesenchymal origin. Even though intracranial, especially intraventricular, SFTs are rare, this diagnosis should be considered in the differential for intraventricular lesions. Here, report the case of a female in her 60s who underwent a non-contrastenhanced magnetic resonance imaging scan of the brain for new-onset memory issues and headache which revealed a well-circumscribed intraventricular lesion in the right lateral ventricle with vasogenic edema, trapping of the temporal horn, and subfalcine herniation. She was admitted and started on dexamethasone prior to surgical treatment of the tumor. A right-sided superior parietal lobule approach was utilized to reach and resect the lesion. Histopathology was consistent with World Health Organization grade I SFT. Only 10 other cases of lateral ventricular SFTs have been reported in the literature. Intraventricular SFT is a rare diagnosis, and, as such, the literature on this topic mostly consists of case reports. Although the lesion is benign, metastases have been reported, and thus, gross total resection remains the standard of care. This case adds to the paucity of SFTs reported in the literature.

“…On MRI, intracranial SFTs show mixed hypo- to isointensity signals on T1WI. On T2WI, the solid region of tumors shows a mixed hypo-hyperintensity signal, and sometimes a cord-like or patchy hypointensity signal called the “black and white sign” [9] , [10] . On gadolinium-enhanced MRI, tumors are heterogeneously enhanced, solitary lesions with an often irregular edge, clear boundary, and lobulated contour.…”
