Figure 2: (a-c) Axial magnetic resonance imaging demonstrating the frontal arteriovenous malformation surrounded by a low signal hemosiderin rim (a) T1-weighted with contrast enhancement. (b and c) T2-weighted). (d) Transverse T2-weighted magnetic resonance imaging demonstrating the pontine cavernoma. (e and f) Sagittal magnetic resonance imaging demonstrating both the frontal arteriovenous malformation and pontine cavernoma (arrow in e)
