Giant serpentine aneurysms [PDF]
Neurosurgical Focus, 2009 Segal and McLaurin first described giant serpentine aneurysms, based on their distinct angiographic features, in 1977. These lesions are ≥ 25 mm, partially thrombosed aneurysms with a patent, serpiginous vascular channel that courses through the aneurysm.
