[Imaging features of cavernous hemangiomas of the orbit].
Cavernous hemangioma is the most frequent benign tumor of the orbit. The clinical presentation is that of a slowly progressive intra-orbital mass with variable degree of exophthalmos. CT typically demonstrates the presence of a well defined oval or rounded shaped mass but MRI provides superior evaluation of the orbit. The tumor is intra-conal in 80% of cases and usually shows T1W hypo-isointensity, T2W hyperintensity and heterogeneous contrast enhancement that becomes more homogeneous on delayed imaging (5 minutes).
