MENINGIOANGIOMATOSIS - ADVANCED IMAGING AND PATHOLOGICAL-STUDY OF 2 CASES

Meningioangiomatosis (MA) is a rare benign intracranial tumour of unce rtain pathogenesis, with only 33 cases reported in the literature, Ima ging features have been described in 21 cases, only 3 with contrast-en hanced 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 th e differences from other entities such as malignant meningioma, one of the most important differential diagnostic considerations.
