“…It is a rare type of tumor and makes up less than 1% of all intracranial neoplasms [1] , [2] , [3] . Because SFT/HPC and meningiomas present with similar imaging findings, they are often difficult to differentiate [ 4 , 5 ]. However, they do require significantly different treatment methods and surgical planning and have significantly different prognoses.…”

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.

“…12 However, recent reports have shown the usefulness of diffusion-weighted MRI in differentiating angiomatous meningioma from highly vascular tumor such as hemangiopericytoma. 13 In this, the histological evidence of meningothelial tumor cells suggested a diagnosis of angiomatous meningioma. The accompanying large cysts could be regarded as secondary changes related to vascular permeability and transudation of plasma fluid resulting in micro-and macrocavitation of the tissue; a similar mechanism for the formation of cysts has been previously postulated in microcystic and richly vascularized meningiomas.…”

Cyst formation in meningioma is rare and furthermore, cyst formation in angiomatous variant of meningioma is extremely rare. Here, we are reporting an unusual angiomatous variant of meningioma with extensive cystic changes mimicking supratentorial hemangioblastoma. The tumor was detected in a 42-year-old woman who presented with left-sided hemiparesis. Magnetic resonance imaging of the brain revealed a large-sized cystic tumor with a contrast-enhancing nodule in the right posterior frontal region. Total excision of the tumor was achieved and left hemiparesis improved.

“…SFT/HPCs tended to show heterogeneous enhancement and necrosis due to its aggressiveness and fast growth. AMs usually show homogeneous enhancement, but 1 was reported to have a large volume, and necrosis was rare [20]. In our study, in addition to classifying types of TIC, we determined and compared the values of SImax, Tmax, MCER, and EER of the 2 kinds of tumors, although only MCER was significantly different between groups.…”

Background To determine if ADC and DCE-MRI can be used to differentiate angiomatous meningiomas (AMs) from solitary fibrous tumors/hemangiopericytomas (SFT/HPCs). Material/Methods We retrospectively reviewed records of 103 patients from 1 January 1 2014 to 1 November 2018. We enrolled 41 patients who had undergone a 3T MRI, with histologically confirmed AMs in 20 (48.80%) patients, and SFT/HPCs in 21 (51.20%) patients. The ADC and DCE-MRI features were derived and then compared by 2 independent-samples t tests and Wilcoxon rank sum test to obtain the ROC. Results AMs had significantly lower ADC values than did SFT/HPCs, but AMs had significantly higher MCER values than did SFT/HPCs. A threshold value of 1.03×10 −3 mm 2 /s for ADC to predict AMs from SFT/HPCs was estimated (AUC=0.902, sensitivity=88.20%, specificity=83.30%). Optimal diagnostic performance (AUC=0.825, sensitivity=84.60%, specificity=81.80%) was obtained when setting MCER=226.7% as the threshold value. Conclusions The ADC values of AMs were lower than those of SFT/HPCs; the MCER of AMs were greater than those of SFT/HPCs, and ADC was more useful than MCER, and these parameters could help diagnosis.
