What’s the diagnosis?
- Cerebral aneurysms larger than 25 mm are termed giant aneurysms.
- Giant saccular and fusiform intracranial aneurysms commonly have spontaneous, intraluminal thrombotic events.
- These aneurysms are considered to be unstable. It is unpredictable when they will undergo partial or complete thrombosis and when thrombosis does occur thrombus may become dislodged and embolize distally to downstream vessels and cause ischemic stroke.
