title: Unusual MR features in a case of completely thrombosed giant aneurysm of the posterior cerebral artery.
abstract: An unusual case of completely thrombosed giant aneurysm of the left posterior cerebral artery, showing much more loss of signal on T2-weighted images compared with T2*-weighted images in the periphery of the thrombus is presented. Possible mechanism of this preferential signal loss on T2-weighted images is discussed.
