a Head CT on admission demonstrating bifrontal small subdural hematomas (orange arrows) and underlying bilateral hemorrhagic contusions (red arrows). b Head CT on day 4, shortly after IV iron administration, demonstrating significant expansion of perihematomal edema (PHE) (red arrows). c, d Head CT axial (at the level of midbrain) and sagittal planes, respectively, obtained immediately prior to EVD placement (approximately 12 h after iron administration)- notice compression of the ambient cistern (green arrow) and dilatation of the temporal horn of the right lateral ventricle (blue arrow)
