Abstract.

Meningioangiomatosis is a rare, benign neoplastic disorder involving the cortex and leptomeninges. The pathological findings are characterised by proliferation of meningothelial cells and leptomeningeal vessels and calcifications within the mass. We experienced two cases of pathologically confirmed meningioangiomatosis, one as a solitary cortical mass with calcification and the other as a cortical lesion manifested as extensive intracranial haemorrhage. On MRI, the first case showed an isointense cortical mass in the left frontal lobe and homogeneous enhancement on the contrast-enhanced study. The second case showed a target-like lesion with a peripheral dark signal rim on T2-weighted images accompanied by extensive haemorrhage in the adjacent frontal lobe and lateral ventricles.
