Figure 1: Axial CT and MRI images of the occipital hemangioma. (a) CT shows a rounded calcified lesion in the post fossa with peripheral spiculated calcifications. (b) On MRI, axial T1W shows it is iso to hypointense with a pattern of peripheral striations with soft tissue infiltration,the 4th ventricle is effaced and hydrocephalus is noted. (c) Post contrast axialT1W shows bright enhancement on gadolinium contrast injection. (d) Axial T2W, it appears isointense with areas of hyperintensity. (e) MRA shows complete occlusion of the right transverse sinus
