Neuroradiological findings of atypical meningiomas
Neuroradiological findings of atypical meningiomas were retrospectively reviewed in 8 patients to clarify their characteristics. Partial or complete disappearance of the peritumoral band was seen in a majority of tumors. More than half of the tumors exhibited heterogeneous density or intensity, heterogeneous contrast enhancement, lack of dural tail sign, and a relatively large perifocal edema. The tumors sometimes showed early venous filling on angiography that is not seen in benign lesions. CT, MRI, and angiographic findings gave useful information for the possible diagnosis of the atypical meningiomas before surgery.
