Angiomatous Meningioma: CT and MR Imaging Features

giomas on computed tomography (CT) and magnetic resonance imaging (MRI) are easily identified and hence, easy to diagnose (1). However, certain meningioma subtypes have unusual imaging findings, making it difficult to diagnose them as well as determining the appropriate treatment protocol. This is particularly true for rare meningioma subtypes, which include the angiomatous meningioma, which shows unusual imaging features compared to ordinary meningiomas. To our knowledge, there are few studies regarding angiomatous meningiomas that describe both pathological and clinical features (2, 3). Moreover, their imaging features have not been reported thus far. In this paper, we aimed to characterize the CT and MR imaging features of angiomatous meningiomas. J Korean Soc Radiol 2011;64:429-434
