Intracranial meningeal solitary fibrous tumors (SFT) originating from mesenchymal tissue are much less common than those with lesions of the visceral pleura or liver and were isolated as a nosological form only in 1996. These tumors are identical in clinical manifestations, MRI and light microscopy data to meningiomas. The pathognomonic difference of SFT, according to the 5th edition of the WHO classification, is the detection of overexpression of the protein encoded by the gene.

To date, any radiological features have been recognized and diagnosis of myopericytoma with intrathoracic localization remains still challenging.
