Centered in the left scalp near the vertex, there is a large multilobulated heterogeneous soft tissue mass. The lesion contains fat density components as well as coarse/punctate calcifications. This measures up to 12 cm in the oblique craniocaudal dimension. The mass extends to the outer table of the calvarium, but no osseous invasion or periosteal reaction is seen.
Post contrast images demonstrate numerous bilateral (right and left) feeding vessels and avid enhancement of portions of the lesion.
