Skull hemangioma, MR

A large, well defined, expansile diploic space lesion is noted involving the left frontal bone, with slight hypo- and hyperintensity relative to brain on T1- and T2-weighted images. There is prominent enhancement, due to the presence of abundant vessels therein, which microscopically can be capillary, cavernous, or mixed in type.
