Abstract

We report three cases of superficial siderosis of the central nervous system examined with MR susceptibility-weighted imaging (SWI) technique additional to the conventional SE sequence. Deposition of hemosiderin on SWI images is thicker and far more conspicuous compare with conventional T2-weighted images. Additional intracerebral bleeds are evidenced on susceptibility-weighted images in all three cases, which provide possible clues to the underlining etiology of superficial siderosis.
