Abstract
Meningioangiomatosis (MA) is a rare benign intracranial tumour of uncertain pathogenesis, with only 33 cases reported in the literature. Imaging features have been described in 21 cases, only 3 with contrast-enhanced MRI. We present two cases of MA with MRI and/or CT findings and gross, ultrastructural, and immunohistochemical characteristics. MRI is particularly helpful for establishing the origin of the lesion and its anatomical location, while CT shows calcification, if present. The pathological characteristics establish the diagnosis and underline the differences from other entities such as malignant meningioma, one of the most important differential diagnostic considerations.
