Unusual MR features in a case of completely thrombosed giant aneurysm of the posterior cerebral artery.
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.
