Abstract

Masson's hemangioma is a rare benign vascualr condition with a papillary intravascular endothelial proliferation which may appear either as aprimary form or as a secondary form in a pre-existing vascular process.CT and angiographic features of 2 cases with Masson's hemangioma were presented. Both of them were locatedextra-axially in the posterior fossa. CT findings were not specific in both cases: One showed homogeneously enhancing mass, simulating meningioma. And the other demonstrated a multiolocular rim enhancing mass. However, the angiographic features were rather characteristic; Both cases showed persistent vascular poolings of contrast mediawhich were supplied form the meningeal vessels. Angiographic differential diagnosis of similar lesions in theposterior fossa is discussed.
