Magnetic resonance (MR) imaging of a cavernous hemangioma in an asymptomatic 52-year-old man. Panel A: Heavily T2-weighted MR image shows the masses (arrows) as very high signal intensity. Panels B-D: Dynamic T1-weighted gradient-echo MR images before (B), during the arterial-phase of gadolinium chelate-enhancement (C), and during the portal phase of enhancement (D) show initial nodular peripheral enhancement (arrowheads) that starts to fill in the hemangiomas (arrows).
