Thin, signal void rims have been noted to surround intracerebral hemorrhages and ruptured intracranial aneurysms on magnetic resonance imaging. Proposed mechanisms include hemosiderin deposition in macrophages and high blood flow. The authors describe an example of a thick, signal void ring in a peripheral luminal thrombus of a giant vertebral aneurysm.
