Description
Summary:The utility of magnetic resonance angiography is sometimes 1imited in the diagnostic workup of cerebral aneurysms with low flow and/or partial thrombosis when weighed against digital subtraction angiography. We present the case of a rare superior cerebellar artery giantl partially thrombosed aneurysm in which additional i.v. contrast-enhanced MRA sequences were comparable to digital subtraction angiography. It demonstrated not only the exact spatial resolution and correct anatomical relation but also the hemodynamics which were confirmed by intraoperative Doppler ultrasound. This report supports the feasibility and utility of i. v. contrast-enhanced MRA for posterior fossa giant cerebral aneurysm management. [Neural Res 1998; 20: 705-708]
