| Discussion | Background - a distinct subtype of benign meningioma that may lack the classic appearance and manifestation of typical meningothelial meningiomas. Pathology - whorl formation around sclerotic vessels, with tumor cells demonstrating glial fibrillary acidic protein expression cf. typical fibrous meningioma shows parallel and interlacing bundles of spindlelike cells embedded in a matrix of collagen and reticulin Radiologic findings - CT : poor or partial enhancement is seen and calcification is more common cf. classic meningothelial meningioma : a relatively hyperattenuating, broad based extraaxial mass with a smooth or lobulated outline that enhances homogeneously with contrast material administration - MR : T2-weighted MR imaging demonstrates a mass with low signal intensity, which corresponds to the psammomatous calcification seen at histopathologic analysis Reference> RadioGraphics 2003; 23:785–789 |
